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 without
pretreatment. In this case however, the recovery
rate is reduced. The decisive factor is the
water analysis.
Unit design
Stainless steel base frame with plastic front
panel housing the instruments and controls
Special inlet filter with 5 µm filter
cartridge and 2 pressure gauges, 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 feedwater
sampling valve, 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. 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.
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 pretreatment.Optional
equipment
Hardness Monitoring Unit limitron _"
for constant monitoring of the feedwater hardness,
completely integrated in the reverse osmosis
unit. Code-no. 370038
