00380620	Reverse Osmosis Unit UO-ED 50 Z		

Reverse Osmosis Unit for desalination of softened drinking water according to German drinking water regulations (free chlorine not detectable).

Counter Pressure Unit designed for supply of permeate under pressure up to 7 bar.

Installation in hygienic design to prevent biological contamination.

For direct supply of several users (e.g. humidifiers) with water according VDI 6022, without interposed permeate storage tank.

The Unit UO-ED Z operates with the controller RO digital for fully automatic monitoring and control of the RO system with automatic logging of all relevant operating data.

Unit design

Stainless steel base frame with plastic front panel.

Special inlet filter with 5 µm-filter cartridge, 
high pressure pump, rotary vane type, 
low energy wound module with energy saving PA/PS composite membranes in GRP pressure vessels.

Valves such as sampling valves for feed water and permeate, solenoid inlet valve, valves to regulate the flow rate of permeate and concentrate.

Pressure sensors for pump feed pressure, operating pressure and concentrate pressure.

Flow meters for permeate and concentrate.

Conductivity measurement permeate with temperature compensation.

Valves for internal permeate recirculation or permeate supply.

Forced flow through diaphragm pressure vessel for permeate.

Screw connection for manual cleaning unit.

Connecting cable (3 m) with 16 A - 6 h CEE three-pole plug.

Microprocessor control system RO digital for fully automatic monitoring and control of the RO system with automatic logging of all relevant operating data (digital and analogue inputs), with programmable logging interval.

4 line illuminated LCD clear text display (20 characters per line) for visualisation of RO process and relevant measuring values. Simple menu guided operation of the controller by 6 keys.

Password secured programming.

The unit is designed for a maximum TDS of 1,000 mg/l, a water
temperature of 15°C, a maximum colloidal index of 3 and permeate back pressure. Under these conditions, the unit still reaches the designed permeate flow after three years of operation. The permeate recovery depends on the raw water quality and the type of pre-treatment.

*At constant feed pressure and with special adjustments up to 6 bar.
