Reverse osmosis units UO 50 – UO 500
Reverse osmosis units demineralise portable water
by applying high on semipermeable membranes.
In doing so the water is divided into a concentrate (25%) and a permeate
(75%)
The desalination rate of the permate with of a one-step reverse osmosis
unit amounts to 97%.
We offer reverse osmosis units with a permeate flow rate up to 10 m³/h.
Stand-type units including pre-treatment for desalination of drinking water according to German drinking water regulations (free chlorine not detectable), according to the principle of reverse osmosis.

Unit design
Stainless steel base frame with control panel
for all operation and displaying elements
Pre-filtration with a 100 µm filter cartridge, 2 pressure gauges
Backflow (EA1) preventer according to DIN 1988 pt.4 Compact water
softener.
Special inlet filter with 5 µm-filter cartridge and 2 pressure gauges,
high pressure pump as rotary-vane type, high performance wound module(s)
with PA/PS composite membranes in GRP pressure vessel(s) with inliner.
Mountings such as stainless valves for feedwater, solenoid inlet valve,
feedwater pressure switch, permeate and concentrate flow meter,
vibration-cushioned pressure gauge for pump- and concentrate pressure,
stainless steel valves for adjustment of permeate and concentrate flow
rate.
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 exceed of conductance
value, LEDs for operation and disinfection, inputs (low vol-tage) for
level control with 1 or 2 float switches, hardness monito-ring 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).
During the regeneration of the softening unit no permeate is produced.
Softening units for the type UO50 are time controlled, for types UO100 –
UO400 controlled by flow-meter.
Due to the integrated system components there is no piping of the
individual components on site.

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 and free permeate outlet. Under these conditions, the units still reach the projected permeate flow also after 3 years of operation. The permeate recovery depends on the raw water quality and the type of pretreatment.
