1 DESCRIPTION OF THE PROCESS
1.1 REVERSE OSMOSIS RO is the abbreviation for reverse osmosis. The word Osmosis has its origin in the greek language, osmos = pressure, thrust. Osmos is the capability of liquids and liquid soluble substances to permeate a membrane. Osmosis takes place when two solutions of different concentrations are on either side of a membrane. The highest concentrated solution will always attract water from the weaker until the same concentration is attained on both sides of the membrane. This occurs under the condition that the water, and not the dissolved substance, can pass through the membrane. The membrane is permeable for one substance but not the other i.e. semi permeable or partially penetrable. It´s used to separate different substances. RO involves utilizing osmosis with the help of technology. By raising the pressure of the “contaminated” liquid, the water is forced through a synthetic, semi permeable membrane, which separates the smallest particles, molecules and ions, and only allows clean water to pass.
The membrane is fitted in a pressurized vessel. This construction is referred to as an RO-module or just module.

1.2 FUNCTION Before the water is desalinated in the membrane, the water must be free from chlorine, iron, aluminum, silicic acid, particles, organic and biological contaminants, etc. It´s common that the feed water is pretreated before it passes through the system. Pretreatment is intended to reduce particles and contaminants that would otherwise damage the membrane, block piping or damage the high pressure pump. The water filter requires a certain pressure to be able to clean the water. To achieve the necessary pressure, a feed water pump raises the pressure of the feed water before it reaches the filter. Thereafter, the water flows through a second filter to remove smaller particles, and then through a high pressure pump. The pump increases pressure of feed water until it exceeds the osmotic pressure, before the water is desalinated in the membrane. It´s important for the high pressure pump, that water keeps required working pressure when passing, lower pressure can result in pump failure. A pressure control valve is installed before the pump. It automatically stops the flow of water if the pressure is too low. After the water has passed the RO-module, two flows are produced. One is desalinated water and the other is salt concentrate (brine). The brine is immediately discharged. The treated water (product water) from the RO-module passes through a conductivity cell that measures the conductivity in the product water. If the conductivity is too high, the water is automatically discharged through a 3-way magnetic valve.

2 MEMBRANE FOULING Membran-fouling is a complex phenomenon which involves trapping material in the fibre bundle or on the surface of the membrane inside the RO-module. When a RO-module fouls, the salt concentration of the product water usually increases. The conductivity meter shows higher conductivity. When it has reached an unacceptable level is it time for chemical treatment. The following foulings are the most common:
- Scaling
- Metal oxides
- Particulate matter
- Colloids
- Biological matter
- Hydrolyse by chlorine
2.1 SCALING Scaling is caused by deposits of minerals. A high concentration of minerals as CaCO3 and CaSO4 precipitate in the RO-module.
2.2 METAL OXIDES Fouling with metal oxides is caused by the formation of the oxide and/or the hydroxide of iron, manganese or aluminium, but iron is the most common reason. Iron fouling can be avoided by selecting the best non corrosive material on the feedwater side of the unit. Fouling by metal oxides is identified by rapid conductivity increasing (within 24 hours) to a level of full scale on the meter.

730108-D 2013-05-10
2.3 PARTICULATE FOULING the mechanical filtration of particulate matters which are Particulate plugging is caused by big particles (larger than 20 micron) stucked between the walls of the membrane. To avoid particulate plugging, be sure that right micro cartridge is used and is properly installed.
2.4 COLLOIDAL FOULINGS Colloidal fouling is caused by coagulation of colloids at the membrane surface. Colloids are very small particles usually ranging from 0,3 to 1,0 micron in size. To avoid colloidal fouling do not operate the unit in harbours and water which is polluted. If the unit is intended to be operated in such water, an extended pre-treatment section is required.
2.5 BIOLOGICAL FOULINGS Biological fouling occurs when feed water contains sufficient nutrients, to sustain rapid growth of organisms inside the RO-module. This growth leads to deposition of slimes. To avoid biological fouling, do not operate the unit in water which is strongly contaminated with bacteria. Such as harbour water etc.
2.6 HYDROLYSE BY CHLORINE If the unit is operated with water containing chlorine, water needs a pre-treatment. Use a carbon filter or a dosage of chemicals to reduce chlorine contents, see membrane manufacturers data sheet. Chlorine, even in very week concentration will cause damage to membranes. Flush water from storage, can sometimes contain chlorine e.g. when the water tanks have been filled up with water which contains chlorine. It is of highest importance that the carbon cartridge is properly installed in the filter house for flush water and has not been replaced by a normal cartridge filter. Normal seawater does not contain any chlorine.

3 CLEANING
3.1 CLEANING AGENTS There are three different agents used for cleaning:
1. MT 10 P3-ultrasil 10 pH 12,5 Useful in removing inorganic scale (e.g. calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate) and metal oxides/hydroxides (e.g. iron, manganese, nickel, copper, zinc), and inorganic-based colloidal material.
2. MT 20 Sulfamic Acid pH 1,2 Useful for removing calcium sulfate scale and to moderate levels of organic foulants of natural origin.
3. MT 5 Biosperse 250 microbiocide Useful in the removal of organic foulants of natural origin and biological material (fungi, mold, slimes and biofilm).
3.2 CLEANING ORDER When performing a cleaning, both low pH and high pH agents are used. The agents are used in the following order:
3.3 STERILIZATION When performing a sterilization, microbiocide is used, but high pH agent is used as pre-treatment. The agents are used in the following order:
3.4 CLEANING AND STERILIZATION PROCEDURES Cleaning and sterilization of the unit is done with the following procedures:
− Water is produced to the cleaning tank (don´t use chlorinated fresh water). − Chemical agent is mixed in the cleaning tank. − The solution is circulated in the system. − Circulation is stopped, and the solution is soaked in. − The solution is circulated. − The solution in the container is discharged. − Feed water is connected and the system is started.

6 INSTALLATION
6.1 FEED WATER Install pump under the waterline, with pump shaft horisontal and outlet facing upwards, this is done to avoid air accumulation in pump. Connect inlet or inlet section to a cleanable coarse filter.
When using feedwater with constant pressure (without feedwater pump), an automatic feedwater valve must be installed and connected to the electrical cabinet according to the wiring diagram.
6.2 PRODUCT Product water from RO-unit is led to fresh water tank.
6.3 DISCHARGED BRINE AND PRODUCT WATER Connect product water and brine discharge outlet so that neither seawater nor contaminated water can flow backwards when the system is stopped. The water must be released above the waterline. When the system is stopped, air flows backwards into the RO-module to prevent vacuums from being created in the system.

SPECIFICATIONS: Maximum specifications refer to individual attributes. It is notimplied that all maximums can be performed simultaneously . If more than onemaximum is considered, check with your CAT PUMPS supplier to confirm the proper performance and pump selection. Refer to individual pump Data Sheets forcomplete specifications, parts list and exploded view.
LUBRICATION: Fill crankcase with special CAT PUMP oil per pump specifications[84 oz., 2.5 L]. DO NOT RUN PUMP WITHOUT OIL IN CRANKCASE. Change initial fill after 50 hours running period. Thereafter, change oil every 3 months or500 hour intervals. Oiler adjustment is vertical to start feed, horizontal to stopfeed, dial to adjust flow rate. Additional lubrication may be required with increasedhours of operation and temperature.
PUMP ROTATION: Pump was designed for forward rotation to allow optimum lubrication of the crosshead area. Reverse rotation is acceptable if the crankcase oillevel is increased slightly above center dot to assure adequate lubrication.
PULLEY SELECTION: Select size of motor pulley required to deliver the desiredflow from Horsepower Requirement and Pulley Selection Chart (refer to TechBulletin 003 or individual Data Sheet).
MOTOR SELECTION: The motor or engine driving the pump must be of adequatehorsepower to maintain full RPM when the pump is under load. Select the electricmotor from the Horsepower Requirement Chart according to required pump discharge flow, maximum pressure at the pump and drive losses of approximately3-5%. Consult the manufacturer of gas or diesel engine for selection of the properengine size.
MOUNTING: Mount the pump on a rigid, horizontal surface in a manner to permitdrainage of crankcase oil. An uneven mounting surface will cause extensive damage to the pump base. To minimize piping stress, use appropriate flexiblehose to inlet and discharge ports . Use the correct belt; make sure pulleys arealigned. Excessive belt tension may be harmful to the bearings. Hand rotate pumpbefore starting to be certain shaft and bearings are free moving.
LOCATION: If the pump is used in extremely dirty or humid conditions, it is recommended pump be enclosed. Do not store or operate in excessively high temperature areas or without proper ventilation.
INLET CONDITIONS: Refer to complete Inlet Condition Check-List in this manualbefore starting system. DO NOT STARVE THE PUMP OR RUN DRY.Temperatures above 130°F are permissible. Add 1/2 PSI inlet pressure per eachdegree F over 130°F. Elastomer or RPM changes may be required. See TechBulletin 002 or call CAT PUMPS for recommendations.
C.A.T.: Installation of a C.A.T. (Captive Acceleration Tube) is recommended in applications with stressful inlet conditions such as high temperatures, booster pumpfeed, long inlet lines or quick closing valves.
DISCHARGE CONDITIONS: OPEN ALL VALVES BEFORE STARTING SYSTEM toavoid deadhead overpressure condition and severe damage to the pump or system.
Install a Pulsation Dampening device on the discharge head or in the discharge lineas close to the head as possible. Be certain the pulsation dampener (Prrrrr-o-lator) isproperly precharged for the system pressure (see individual Data Sheet.)
A reliable Pressure Gauge should be installed near the discharge outlet of the highpressure manifold. This is extremely important for adjusting pressure regulating devices and also for proper sizing of the nozzle or restricting orifice. The pump israted for a maximum pressure; this is the pressure which would be read at the discharge manifold of the pump , NOT AT THE GUN OR NOZZLE.
Use PTFE liquid (sparingly) or tape to connect accessories or plumbing. Exercisecaution not to wrap tape beyond the last thread to avoid tape from becoming lodged in the pump or accessories. This condition will cause a malfunction of thepump or system.
PRESSURE REGULATION: All systems require both a primary pressure regulatingdevice (i.e., regulator, unloader) and a secondary pressure safety relief device (i.e., pop-off valve, safety valve). The primary pressure device must be installed onthe discharge side of the pump. The function of the primary pressure regulating device is to protect the pump from over pressurization, which can be caused by aplugged or closed off discharge line. Over pressurization can severely damage thepump, other system components and can cause bodily harm. The secondary safetyrelief device must be installed between the primary device and pump. This will ensure pressure relief of the system if the primary regulating device fails. Failure toinstall such a safely device will void the warranty on the pump.
If a large portion of the pumped liquid is by-passed (not used) when the high pressure system is running, this by-pass liquid should be routed to an adequatelysized, baffled supply tank or to drain. If routed to the pump inlet, the by-pass liquidcan quickly develop excessive heat and result in damage to the pump. A temperature control device to shut the system down within the pump limits or multipleTHERMO VALVES must be installed in the by-pass line to protect the pump.
NOZZLES: A worn nozzle will result in loss of pressure. Do not adjust pressure regulating device to compensate. Replace nozzle and reset regulating device tosystem pressure.
PUMPED LIQUIDS: Some liquids may require a flush between operations or beforestoring. For pumping liquids other than water, contact your CAT PUMPS supplier.
STORING: For extended storing or between use in cold climates, drain all pumpedliquids from pump and flush with antifreeze solution to prevent freezing anddamage to the pump. DO NOT RUN PUMP WITH FROZEN LIQUID (refer to TechBulletin 083).
INSTALLATION AND START-UP INFORMATIONOptimum performance of the pump is dependent upon the entire liquid system and will be obtained onlywith the proper selection, installation of plumbing, and operation of the pump and accessories.
WARNINGAll systems require both a primary pressure regulating device (i.e., regulator, unloader) and a secondary pressure safety relief device (i.e., pop-off valve, safety valve). Failure to install such relief devices could result in personal injury or damage to the pump or to system components. CAT PUMPS does not assume any liability or responsibilityfor the operation of a customer’s high pressure system.

* If other than CAT PUMPS special multi-viscosity ISO68 oil is used,change cycle should be every 300 hours.
** Each system’s maintenance cycle will be exclusive. If system per-formance decreases, check immediately. If no wear at 1500 hours,check again at 2000 hours and each 500 hours until wear is ob-served. Valves typically require changing every other seal change.Duty cycle, temperature, quality of pumped liquid and inlet feedconditions all effect the life of pump wear parts and service cycle.
** Remember to service the regulator/unloader at each seal servicingand check all system accessories and connections before resumingoperation.Refer to video for additional assistance.
INLET CONDITION CHECK-LISTReview Before Start-Up
Inadequate inlet conditions can cause serious malfunctions in the best designedpump. Surprisingly, the simplest of things can cause the most severe problems or gounnoticed to the unfamiliar or untrained eye. REVIEW THIS CHECK-LIST BEFOREOPERATION OF ANY SYSTEM. Remember, no two systems are alike, so there canbe no ONE best way to set-up a system. All factors must be carefully considered.
INLET SUPPLY should exceed the maximum flow being delivered by the pump toassure proper performance.❏ Open inlet shut-off valve and turn on water supply to avoid starving pump. DO
NOT RUN PUMP DRY.❏ Temperatures above 130°F are permissible. Add 1/2 PSI inlet pressure per each
degree F over 130°F. Elastomer or RPM changes may be required. See TechBulletin 002 or call CAT PUMPS for recommendations.
❏ Avoid closed loop systems especially with high temperature, ultra-high pressureor large volumes. Conditions vary with regulating/unloader valve.
❏ Low vapor pressure liquids, such as solvents, require a booster pump and C.A.T.to maintain adequate inlet supply (where compatible).
❏ Higher viscosity liquids require a positive head and a C.A.T. to assure adequateinlet supply.
❏ Higher temperature liquids tend to vaporize and require positive heads andC.A.T. to assure adequate inlet supply.
❏ When using an inlet supply reservoir, size it to provide adequate liquid to accommodate the maximum output of the pump, generally a minimum of 6-10times the GPM (however, a combination of system factors can change this requirement); provide adequate baffling in the tank to eliminate air bubbles andturbulence; install diffusers on all return lines to the tank.
INLET LINE SIZE should be adequate to avoid starving the pump.❏ Line size must be a minimum of one size larger than the pump inlet fitting. Avoid
tees, 90 degree elbows or valves in the inlet line of the pump to reduce the risk offlow restriction and cavitation.
❏ The line MUST be a FLEXIBLE hose, NOT a rigid pipe, and reinforced on SUCTIONsystems to avoid collapsing.
❏ The simpler the inlet plumbing the less the potential for problems. Keep thelength to a minimum, the number of elbows and joints to a minimum (ideally noelbows) and the inlet accessories to a minimum.
❏ Use pipe sealant to assure air-tight, positive sealing pipe joints.
INLET PRESSURE should fall within the specifications of the pump.❏ Acceleration loss of liquids may be increased by high RPM, high temperatures,
low vapor pressures or high viscosity and may require pressurized inlet and C. A.T. to maintain adequate inlet supply. DO NOT USE C.A.T. WITH SUCTION INLET.
❏ Optimum pump performance is obtained with +20 PSI (1.4 BAR) inlet pressureand a C.A.T. for certain applications. With adequate inlet plumbing, most pumpswill perform with flooded suction. Maximum inlet pressure is 70 PSI (4.9 BAR).
❏ After prolonged storage, pump should be rotated by hand and purged of air to facilitate priming. Disconnect the discharge port and allow liquid to pass throughpump and measure flow.
INLET ACCESSORIES are offered to protect against over pressurization,contamination or temperature and control flow.❏ A shut-off valve is recommended to facilitate maintenance.❏ Installation of a C.A.T. is essential in applications with stressful conditions such
as high temperatures, booster pump feed or long inlet lines. Do not use C.A.T.with negative inlet pressure.
❏ A stand pipe can be used in some applications to help maintain a positive headat the pump inlet line.
❏ Inspect and clean inlet filters on a regular schedule to avoid flow restriction.❏ A pressure transducer is necessary to accurately read inlet pressure. Short
term, intermittent cavitation will not register on a standard gauge.❏ All accessories should be sized to avoid restricting the inlet flow.❏ All accessories should be compatible with the solution being pumped to prevent
premature failure or malfunction.❏ Optional inlet protection can be achieved by installing a pressure cut off switch
between the inlet filter and the pump to shut off pump when there is no positiveinlet pressure.
BY-PASS TO INLET Care should be exercised when deciding the method of by-passfrom control valves.❏ It is recommended the by-pass be directed to a baffled reservoir tank, with at
least one baffle between the by-pass line and the inlet line to the pump. ❏ Although not recommended, by-pass liquid may be returned to the inlet line
of the pump if the system is properly designed to protect your pump. When a pulsation dampener is used, a PRESSURE REDUCING VALVE must be installed on the inlet line (BETWEEN THE BY-PASS CONNECTION AND THEINLET TO THE PUMP) to avoid excessive pressure to the inlet of the pump. It isalso recommended that a THERMO VALVE be used in the by-pass line to moni-tor the temperature build-up in the by-pass loop to avoid premature seal failure.
❏ A low-pressure, flexible cloth braid (not metal braid) hose should be used fromthe by-pass connection to the inlet of the pump.
❏ Caution should be exercised not to undersize the by-pass hose diameter andlength. Refer to Technical Bulletin 064 for additional information on the size andlength of the by-pass line.
❏ Check the pressure in the by-pass line to avoid over pressurizing the inlet.❏ The by-pass line should be connected to the pump inlet line at a gentle angle of
45° or less and no closer than 10 times the pump inlet port diameter e.g. 1-1/2"port size = 15" distance from pump inlet port.

DIAGNOSIS AND MAINTENANCE
One of the most important steps in a high pressure system is to establish a regular maintenance program. This will vary slightly with each system and is determined by various elements such as the duty cycle, the liquid being pumped, the actual specifications vs rated specificationsof the pump, the ambient conditions, the inlet conditions and the accessories in the system. A careful review of the necessary inlet conditionsand protection devices required before the system is installed will eliminate many potential problems.
CAT PUMPS are very easy pumps to service and require far less frequent service than most pumps. Typically, only common tools are required,making in-field service convenient, however, there are a few custom tools, special to certain models, that do simplify the process. This servicemanual is designed to assist you with the disassembly and reassembly of your pump. The following guide will assist in determining the causeand remedy to various operating conditions. You can also review our FAQ or SERVICE sections on our WEB SITE for more facts or contactCAT PUMPS directly.

730153-I 2012-10-15
7 FUNCTION The filter works in two different modes:
- Filtration mode, service position - Regeneration mode
FILTRATION MODE The incoming water pass down through the filter and gets treated by the material in the tank. The water is then lead out through the valve. The filter works automatically.
REGENERATION MODE After a number of working hours, the material needs to be regenerated. In the regeneration mode the filter works through a cycle/program with different operations.
1. Backwash The incoming water passes up through the filter material. The water is lead to drain. When the filter is backwashed, the material is lifted and accumulated particles are flushed to drain.
2. Rinse The incoming water passes down through the filter is flushed to drain.
NOTE! The water consumed during regeneration is not filtrated.
NOTE! The minimum water pressure that can guarantee an adequate effect of the backwash is 2 bars. Check that the required flow rate has been reached. (chapter 12)

Problems that can arise from neglecting to follow these recommendations could lead to that the product guarantees for the equipment are withdrawn.
3 OVERALL CHARACTERISTICS ENWA’s water cleaning filters are filters where the water runs through a container filled with filter material which is adjusted for the incoming water quality. The water which is to be cleaned passes through the water filter in which the impurities sticks to the filter material. After some usage the filter is cleaned by an automatic flushing process and the impurities are removed into the drain.
4 INTENDED AREA OF USAGE ENWA’s water cleaning filters are constructed and manufactured to purify water in normal, industrial and household applications. The water filters must not be used in premises where there is obvious risk for fires, for example in connection with storage of explosive liquids, gases and other substances. In applications where the water, after passing the cleaning filter, is to be stored in a tank, proper equipment should be installed after the tank, to ensure the quality of the water. For more information consult with the supplier. The water filter is only to be used in applications to which it’s originally intended for and in accordance with the instructions in this manual. All other usage of the equipment is incorrect and will make the supplier and the manufacturer to revoke all their responsibilities and guaranties for the equipment as well as complaints, injuries and other damages.
5 TRANSPORT AND EQUIPMENT HANDLING The equipment must be lifted and transported in accordance with the following instructions:
Transport if possible the equipment in its original packaging.
Protect the surface of the filter tank when transporting the equipment.
TURN THE PRESSURE OFF BEFORE INTERFERING WITH THE EQUIPMENT. INTERFERENCE WITH THE EQUIPMENT SHOULD ONLY BE MADE BY AUTHORIZED PERSONNEL. THIS EQUIPMENT IS NOT MADE FOR OUTSIDE USAGE.

6 UNPACKING DEPOSIT ALL PACKAGING MATERIAL IN AN ENVIRONMENTAL SUSTAINABLE WAY OR STORE IT FOR FUTURE TRANSPORTATION OF THE EQUIPMENT.
After unwrapping, control that the equipment is complete and without any visible damages. If you’re unsure don’t use it until you have contacted your supplier or the manufacturer for a consultation. All packaging material (e.g. plastic film and bags, nails, screws, wood, metal bands et cetera) should be handled as dangerous goods, especially for children, and be deposited in accordance with the current environmental laws.
7 PLACING OF THE WATER FILTER
7.1 ARRANGEMENT OF THE EQUIPMENT Take the following paragraphs into consideration when placing the filter.
The surface must be totally flat and strong enough to carry the total weight of the equipment.
Make sure there’s enough space around the equipment to fulfil proper usage, maintenance and inspections.
7.2 VENTILATION The placing of the water filter could prolong its lifespan. The room should be large enough, dry and well ventilated. The surrounding room temperature must be 5 - 45°C.
8 INSTALLATION
8.1 CONNECTION TO THE WATER SYSTEM The filter is connected after the RO-unit according to figure 1. Mount a bypass valve to isolate the filter at maintenance and service work.

9 FUNCTION
9.1 FILTRATION POSITION Water from incoming pipe passes through water filter from below, is treated by filter material in the filter tank and passed out through the water filter by an outlet valve. (figure 2)
figure 2. filtration position
9.2 FLUSH POSITION The filter should be flushed on regular basis with a higher flow than the RO-unit has the capacity of. This keeps porosity and prevents the material of solidifying. (figure 3) For required flow rate see chapter 13.

10 FILLING INSTRUCTION The following instruction is to be used when the filter material has been delivered separately or when the filter is refilled.
a) Drain the filter
b) Empty the filter tank
1. Make sure that the filter is without pressure (paragraph 15)
2. Open the filling lid and fill with water (according to the table) to protect the bottom
nozzles.
3. Fill the filter with material according to figure 4.
4. Slowly fill the tank completely with water.
5. Put the lid back.

11 START UP Use the following instructions and figure 5 at first start:
1. Keep all valves for incoming and outgoing lead closed.
2. Open valve D slightly.
3. Open valve C slightly and fill the filter tank slowly with water. Open valve A fully.
4. Open valve D into fully open position.
5. Rinse the filter continuously, until the waste water is clear (approximately 15 min).
6. Open valve B.
7. Close valve D, and the filter is in filtration position.

730230-C 2011-06-16
12 FLUSH Use the following instructions and figure 5 when performing a flush:
1. Close valve A.
2. Open valve D.
3. Close valve B.
4. Open valve C, flush the filter with clean water and let out coming water
Depending on how much water the RO the produce the frequency of the flushing can vary. But it should be flushed about once/month (Use instructions 12).
2-4 times/year
Check the level of filter material (16,CHECKING AND REFILLING OF MAGNO-DOL)
15 DECOMPRESSION Follow the instructions:
Close the inlet and the outlet valve.
Release pressure by opening the drain valve in the bottom of the tank (and then close it).
Stop the RO unit before each service operation

730230-C 2011-06-16
16 CHECKING AND REFILLING OF MAGNO-DOL Magno-Dol is the material used for increasing pH-value. The consumption of material depends on the quantity of carbon dioxide in the water.
Release tank pressure according to paragraph 15.
Open the filling lid and use a measurement rod to see how much material there is left. (figure 6)
figure 6. measurement of material
compare with the sticker on the tank for correct level. (figure 7 and figure 8)
figure 7. level sticker
If necessary, fill up with Magno-Dol.
Mount the filling lid and open the valve on the inlet and the outlet. Make sure the drain valve is closed.
