Stand-type units 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. However, in this case 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 1000 microprocessor control system for
fully automated monitoring and control of
the system with two line next display (16
characters per line) for display of operational
status, permeate conductivity, temperature,
operating hours, password-protected programming
of the operating sequences and parameters
as described below. Operators functions with
password on different levels, low pressure
shut down, conductivity limit fault and conductivity
limit pre-alarm, malfunction displays for
low pressure, hard water/motor overload, high
conductivity pre-alarm, power supply malfunction.
Programming options for the following operating
status with selectable duration:
- discard of permeate, subject to conductivity,
with time limit
- discard of permeate, subject to time
- shut-down at high conductivity
- failure acknowledgement with or without
password
- operators functions via password on different
levels
- low pressure shut-down 0-99 sec.
- conductivity limit delay 0-99 min.
- conductivity limit fault 2-200 µS/cm
- conductivity limit prealarm 2-200 µS/cm
- interval for intermittent rinse when "tank
full" 0-99 h
- duration of rinse when "tank full"
0-99 min.
- duration of concentrate displacement 0-99
min.
- duration of concentrate rinse 0-99 min.
- duration of permeate discard accord. to
conductivity 1-99 min.
- range of permeate conductivity 2-200 µS/cm
- pump delay 0-9.9 sec.
- language German/English/French/Italian
- individual test of all inputs or outputs
with LCD (diagnostics)
Additional connections possible: Inputs (low
voltage) for level control with 1 or 2 float
switches, hardness monitoring unit (the RO
1000 control system includes control functions
for the limitron hardness monitoring unit),
shut-down by external signal (forced stop,
regeneration), Outputs for softener (230 V/50
Hz), 2 solenoid valves for concentrate rinse,
permeate discard and -recycling, and DDC (collective
malfunction signal on volt-free changeover
contact).
Unit completely wired, pre-assembled and
ready for installation. Electrical equipment
in accordance with VDE 0100 part 600, VDE
113 part 1.
The units are designed for a maximum TDS
of 1,000 mg/l, a water temperature of 15°C
and a 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
