For desalination of softened drinking water according to drinking water regulations (free chlorine not detectable). With 4 membrane housings.
Permeate-staged RO System with second permeate stage for treating the permeate of the first stage once again. Thereby a very high quality of permeate is achieved.
membranes: 4040 x 7
Complete unit skid mounted RO 5000 controller Recovery from 70% to 71% Salt rejection percentage: min. 99,5% Working pressure: 14 bar Voltage: 230 V/50 Hz (300) / 3 x 400 V/50 Hz (600 - 2000) Analogue flow meters 2nd permeate stage for high permeate quality Two high pressure pumps
2nd permeate stage for treating the permeate of the first stage once again Salt rejection > 99,5% Conductivity < 5ìS/cm RO 5000 controller with graphical display
*The unit is designed for a maximum TDS of 1,000 mg/l, a max. SiO2-concentration of 10 mg/l, a water temperature of 15°C, a maximum colloidal index of 3 and no permeate back pressure. Under these conditions, the unit still reaches design permeate flow after three years of operation. The permeate recovery depends on the raw water quality and the type of pre-treatment.
