Zoom in

When the reverse osmosis unit is not operating, scaling and fouling can occur, particularly on the concentrate side of the membrane. The concentrate flushing unit KSE prevents this by displacing the concentrate with the pressure of the feed water via an automatic bypass valve (solenoid valve) when the system is shut down. Flushing the membrane with raw water prevents concentrated salt loads from settling on the membrane surface.
The concentrate flushing unit is supplied pre-assembled with the reverse osmosis system.

Benefits

• Ensures a long service life of the membranes

Applications

• Recommended if the feed water tends to scaling or fouling and if the RO is operated with antiscale
• Already included with the UO-S7 KR/FU, UO-D AS/FU and UO-D BW/FU series
• Available as an option for the UO-D (FU, CD) and UP-S7 FU series

Material:

brass

Conditions of use:

The KSE option has to be ordered together with the reverse osmosis unit.
