TECHNICAL PROPOSAL: 1.- DESCRIPTION: The following technical proposal has been designed according the strictest normative in swimming pools design. Taking as reference a standard Olympic pool with the dimensions detailed below, the Technical Department of EMAUX has elaborated the following technical proposal by calculating and designing the best products adapted to the standard requirements in swimming pools. You also will find a recommended Lay-Out of the installation at the end of the proposal, so it will help to clarify the position of all the products designed, as well as some hydraulic topics. 2.- DESIGN OF THE PRODUCTS: EMAUX has designed the products proposed according to the following initial values: • Pool size: 50 x 25 x 2 • Pool volume: 2500 m 3 • Type of pool: Public and training purpose. • Illumination system: LED lights cool white. • Water Temperature: 28 degrees • Water Treatment: Ultraviolet System and chemical dosing pumps. 2.1.- PUMPING SYSTEM: For a proper water filtration, EMAUX recommends that the time required for treating the entire water volume of the pool, also called turn over, must be 4 hours for Semi-Olympic pools. Consequently, the flow rate calculated is: 2500 m 3 / 4 hours = 625 m 3 /h 2.2.- PUMP DESIGNED: High-volume self-priming pump available in 2 and 4 poles versions ideal for larger filtration systems. Features large suction-side pre-filter which together with excellent hydraulic performance ensures extremely high filtration capacity. Filter with polycarbonate cover for easy viewing of pre-filter basket contents. Features standard connection flanges which together with a broad base make the system especially robust. Counter-flanges not supplied as standard (available on request). Turbine available in 2 versions, Noryl or marine bronze, as per request. Works with sea water when fitted with AISI-316 mechanical seal (available on re-quest). Units required Model Flow rate (m3/h) Head (m.w.h) Voltage (V) Power (HP) Connections (mm) 5+1 ES1250B 136 12 380-420V III 50Hz 12.5 4” / 110 mm

According to the purpose of the pool (training), we recommendthedisinfectionsystembasedonUltravioletSystemandchemicaldosingpumps in order to obtain theminimum levels of chlorinerequired.Ultraviolet technology is a non-chemical approach todisinfection. In this method of disinfection, nothing is addedwhichmakesthisprocesssimple,inexpensiveandrequiresvery
