Wall mounting/stand-type 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 with-out pretreatment. However,
in this case the recovery rate is reduced.
The decisive factor is the water analysis.
Unit design
Stainless steel base frame suitable for mounting
on the wall or floor.
Special inlet filter with 5 µm filter
cartridge and pressure gauge, high pressure
pump, rotary-vane type, high performance wound
module(s) with PA/PS composite membranes in
GRP pressure vessel(s) with inliner.
Valves and instruments including solenoid
inlet valve, feedwater pressure switch, permeate
and concentrate flow meter, vibration-resistant
pressure gauges for pump pressure, 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 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 changeover
contact).
Programming options for the following values
(preadjusted/limits)
- conductivity alarm 50/1-99 µS/cm
- conductivity prewarning 40/1-99 µS/cm
- conductivity alarm delay 5/1-250 min.
- interval for intermittent rinse when tank
full 24/1-250 h
- duration of rinse when tank full 15/1-99
min.
- duration of concentrate displacement 60/1-250
sec.
For further information please refer to the operating manual
Programming by manufacturer only.
The units are designed for a maximum TDS
of 1,000 mg/l, a water temperature of 15°C
and a maximum fouling index of 3. 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.
Optional equipment
Hardness Monitoring Unit limitron _"
for constant monitoring of the feedwater hardness,
not integrateable in the reverse osmosis unit.
