RO 524 controller

Zoom in

The ready-to-connect combi unit includes a pre-filter, a backflow preventer, a duplex water softener, a limitron hardness control device and a reverse osmosis unit. It is used for the desalination of water with a salinity of up to 1,000 mg/l and is equipped with a compact rotary vane pump. The RO 524 controller allows fully automatic operation without logging of operation data and with fixed, factory-set limit values.

Benefits

• Complete pre-treatment integrated, can be connected directly to the drinking water network
• Continuous operation due to duplex softener
• Simple installation on site with only four connection points (drinking water, permeate, waste water, socket)
• Cost-effective, factory-preset RO 524 controller

Applications

• Continuous water softening and desalination
• Suitable for commercial and industrial applications that do not require operation data logging and parametrisation

Controller :

RO 524

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 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:

3 – 6 bar

Pressure fluctuation:

± 0.5 bar
