Product Description
The ultrapure water unit is used to produce diluate with a typical conductivity < 0.2 µS/cm by treating reverse osmosis permeate via electrodeionisation (EDI). It is equipped with high quality EDI modules and a Siemens LOGO! controller.
Benefits
Diluate with typical conductivity < 0.2 µS/cm
Prepared for direct connection to an RO unit
Piping in PP
Applications
For further demineralisation of RO permeate
For pharmaceutical or laboratory applications, power plants and microelectronics
Controller : PLC Siemens Logo
Resistance diluate without CO2 binding: 5 M? x cm
Resistance diluate with CO2 binding: 10 M? x cm
Recovery: 90 95 %
Diluate backpressure max.: 1.0 bar
Ambient temperature: 5 - 40 °C
Conditions of use: The unit is designed for a permeate conductivity of 4-20 µS/cm, a CO2 concentration of 10 mg/l and free diluate discharge. The feed water must be softened (< 0.05 °dH) and treated via a reverse osmosis unit without a permeate buffer. The diluate quality depends on the permeate quality. In addition, the following parameters must be maintained in the feed water:
Free chlorine: not detectable
Silica (SiO2): 0.5 mg/l
Silt density index (SDI): < 0.25
Feed water temperature: 5 35 °C
Feed water pressure: 2 4 bar
Pressure fluctuation: ± 0.5 bar
pH value feed water: 5.0 - 9.5
