Reverse Osmosis – Model W250
W Series: 50 – 400 l/h Wall mounting unit. For desalination of softened drinking water according to German drinking water regulations (free chlorine not detectable), operating on the principle of reverse osmosis. Drinking water can also be desalinated without pre-treatment. However, in this case the recovery rate is reduced. The decisive factor is the water analysis.
Stainless steel base frame with hinged plastic front panel housing the instruments and controls. Special inlet filter with 5 μm-filter cartridge, high pressure pump, rotary-vane type, high performance wound module with PA/PS composite membranes in GRP pressure vessel with inliner.
