For all Processes the Applicable Solution

Numerous Industries wordwide are using cooling water in their pro-cesses. In most cases wet cooling towers are used. In efcient op-eration of a closed circuit cooling tower, prime concerns are on the one hand, the reduction of cooling water consumption on the other hand, protecting the entire system from corrosion, sediments and bio-logical growth. The fact about these two require-ments is that they are contradictory. Increasing the thickening process in the circuit water using a desali-nation control device can reduce the fresh water consumption in the cooling tower. As a result however, the number of water substances in-creases, so that cooling tower com-ponents, heat changer as well as piping are strongly affected.

In order to ensure reliable protec-tion of the cooling tower, thus the cooling water is teated by means of metering stabalizers and inhibitors as well as the use of lters.

ProMinent offers metering sys-tems for dosing of anti-corrosive agents, hardness stabilizers and dispersants chemicals; an espe-cially adapted and exactly adjusted measuring and control technology for blowdown and pH-value con-trol; gravity lters for ltration of cooling water in open cooling circuits as well as particularly ef-cient disinfection systems.

The disinfection of cooling water plays a very important role in a cool-ing tower, because the most criti-cal part of the circulation system is the heat exchanger. Due to their thermally insulating effect, biolms deteriorate the heat exchangers efciency. Additionally the micro-organisms discharge corrosive metabolites causing increased wear of materials. The use of biocides for disinfection is indispensable.

The following systems are utilized for disinfection: metering systems for for liquid biozides, chlorine dioxide, ozone or electrolysis sys-tems.

Which system is suited best for spe-cic application depends on many factors. Due to their many years of experience in the eld of cool-ing water treatment, the experts of ProMinent advise each customer individually in order to select the ptimal technology and correspond-ing systems and products.

Metering stations and pumps DULCODOS eco

It almost goes without saying: ProMinent metering stations and pumps are used wherever precise quantities have to be metered whether with disinfectants, pH adjustment or in many other applications. Metering with chlorine for disinfec-tion is a simple, safe and economical method of disinfection. ProMinent metering pumps are standard in water treatment.

Panel-mounted measurement and control pointsDULCOTROL

The online measurement and control units, which are tailored to the requirements of cooling water treatment and optimised in terms of application. All of the components required for measurement, control and monitoring of the different types of water are coordinated with each other and mounted on a PE panel wired ready for connection. The complete measuring point is supplied as standard for the measurement of pH, redox, chlorine, bromine, chlorine dioxide, ozone, hydrogen peroxide and conductivity or a combination of these parameters.

Metering systems DULCODOS panel

Panel-mounted standard metering systems have been designed to meet the specific requirements of cooling water treatment. The pre-assembled systems are based on com-ponents, which have been perfectly coordinated with each other to ensure problem-free operation. You will receive a com-plete system as a plug-and-play module, which you can install and commission quickly and easily.

Flow meterDulcoFlow

The flow meter DulcoFlow allows the measuring and con-trolling of expensive additives. It is designed for the precise measurement of volume flows in metering processes for a measuring range of 0.1 to 50 litres per hour. Based on the ultrasonic measurement method, it records the flow rates of pulsing flows as well as the volume flown through. The DulcoFlow, in its compact universal housing ideally suited for wall-mounting, is directly installed in the pressure line of the metering pump of the medium to be measured. Due to the fact that all media contacting parts are made of chemically resistant PVDF/PTFE, also aggressive media can be meas-ured without any problem. Interfering influences, such as air bubbles, are identified by the DulcoFlow and reported to the analysis unit via fault messages.

Chlorine dioxide systems Bello Zon CDKc

Chlorine dioxide systems wired ready for connection, are used for the production, metering and monitoring of up to 12,000 g/h of chlorine dioxide with concentrated base chemicals. A completely new developed reactor concept ensures the innovative production and metering of chlorine dioxide. This results in higher operating safety and a better purity of the generated chlorine dioxide. Easy and safe opera-tion thanks to clear manu navigation in plain text.

Ozone systemsOZONFILT OZMa

Ozone systems of the OZMa series guarantee zero-maintenance ozone generation up to 735 g/h. The systems are both ecological and economical. Particularly economical is the innovative reactor with a virtually infinite service life. Cost reduction is possible while using the automatic control of the operating gas depending on ozone output. Air drying is controlled by demand and self-optimising which results in energy savings of up to 30 %.

Electrolysis systems CHLORINSITU III

Generate an ultra-pure and low-chloride sodium hypochlorite. Electrolysis takes place in two electrode cham-bers that are separated by a membrane. This creates a spatial separation between the chlorine and sodium hydroxide. The chlorine and sodium hydroxide are combined after electro-lysis for further use and are temporarily stored as a sodium hypochlorite solution.

Cooling Tower and boiler ControllersCool Control and MultiFLEX M10T

The cooling tower controls can provide bleed functions, as well as the precise metering of necessary additives. Cooling plants can therefore be reliably protected from corrosion and sediments. Efficiency losses can be minimized. The continuous monitoring of all relevant parameters by sensors reliably protects the system from incorrect metering.

6Resistant sensorsDULCOTEST sensors CBR 1, BCR 1, CDR 1, PER 1/2

Oxidative disinfectants are used for disinfecting of cooling water. ProMinent developed special transducers the Resistant CDR 1 / PER 1/2 type sensors to measure these disinfectants. Reliable measurements can be taken using the new resistant, online ProMinent sensors even in polluted water like cooling water, which reduces maintenance and increases durability.

Gravity filters INTERFILT SK

Economical water treatment with gravity filters: open sand filter plants with differential pressure-controlled backwash and integral backwash water reservoir work automatically without the need for service and maintenance.

Chemical storage vessels/Chemical tanks

ProMinent storage vessels and tanks guarantee the highest level of reliability in the storage and handling of chemicals and raw materials. Coordinated with the metering equipment, designed and built for each individual use, they store alkaline solutions, acids and other additives reliably and safely.

Polymer preparation and metering stationsUltromat ULFa

Polymer feed stations and metering systems are special developments used for feeding liquid and / or powered polymers. Polyelectrolytes are used as flocculation aids in a broad range of applications where colloidal solids and liquids have to be separated in an economical manner. According to the particular application needed different systems are available.
