RO digital controller

Zoom in

The reverse osmosis unit is used for the desalination of softened water with a salinity of up to 1,000 mg/l. It is equipped with a high-quality centrifugal pump. The microprocessor controller RO digital enables fully automatic operation with logging of all relevant operating data and freely adjustable limit values. The unit can be connected to the central control system via an optional Profinet interface.

Benefits

• Compact unit
• Versatile RO digital controller with logging of operation data and many parametrisation options

Applications

• Desalination of softened water
• Suitable for all commercial and industrial applications

Controller :

RO digital

Desalination rate min.:

97 %

Permeate recovery:

75 – 80 %

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 with drinking water quality or appropriately pre-treated well or surface water. The unit 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:

2 – 6 bar

Pressure fluctuation:

± 0.5 bar
