Reverse Osmosis – Series W
Reverse Osmosis – W Series
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.
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. Valves and instruments including solenoid inlet valve, feedwater pressure switch, permeate and concentrate flow meter, vibration-resistant pressure gauges for pump and concentrate pressure, stainless steel valves for adjustment of permeate and concentrate flow rate and concentrate recirculation. Microprocessor control system as described below, connecting cable (3 m) with 16 A – 6 h CEE three-pole plug. Unit completely wired and pre-assembled and ready for installation. Electrical equipment in accordance with VDE 0100 part 600, VDE 113 part 1.
RO 500 microprocessor control system
For fully automated monitoring and control of the reverse osmosis unit with two-digit alphanumeric display of permeate conductivity, forced stop and full tank, malfunction signals: low pressure, hard water and high conductivity LEDs for operation and disinfection, inputs (low voltage) for level control with 1 or 2 float switches, hardness monitoring unit (the RO 500 controller includes control functions for the limitron hardness monitoring unit), shut-downs by external signal (forced stop, regeneration), outputs for softening unit (230 V / 50 Hz) and DDC (collective malfunction signal on floating change-over contact). The units are designed for a maximum TDS of 1,000 mg/l, a water temperature of 15°C, a max. colloidal index of 3 an free permeate outlet. Under these conditions, the units still reach design permeate flow after 3 years of operation. The permeate recovery depends on the raw water quality and the type of pre-treatment.
