Zoom in

The space-saving under-sink reverse osmosis unit is used for the desalination of softened water with a salinity of up to 1,000 mg/l. If required, operation without upstream softening is also possible, in which case the yield is reduced. The decisive factor is the water analysis. The RO 524 controller allows fully automatic operation without logging of operation data and with fixed, factory-set limit values.

Benefits

• Available from stock
• Space-saving undersink unit
• Desalination of hard water also possible (reduced yield)
• Cost-effective, factory-preset RO 524 controller

Applications

• Desalination of softened water and hard water (consider water analysis)
• Suitable for commercial applications that do not require operation data logging and parametrisation

Controller :

RO 524

Desalination rate min.:

95 %

Permeate recovery:

35 – 50 %

Permeate back pressure max.:

0.3 bar

pH value operation:

6.5 – 9.5

pH value cleaning:

2 – 12

Ambient temperature:

5 – 40 °C

Conditions of use:

The unit may only be used for the desalination of softened feed water of drinking water quality or appropriately pre-treated well or surface water. The plant is designed for a salinity (TDS) of 1,000 mg/l and a temperature of 15 °C. Under these conditions, the projected permeate output is achieved even after three years of operation. The permeate yield depends on the raw water quality and the pre-treatment. The following parameters must be maintained in the feed water:

Free chlorine:

not detectable

Iron (Fe):

< 0.2 mg/l

Manganese (Mn):

< 0.05 mg/l

Silica (SiO2):

< 25 mg/l

Silt density index (SDI):

< 3

Feed water temperature:

5 – 35 °C

Feed water pressure:

3 – 6 bar

Pressure fluctuation:

± 0.5 bar
