Stand-type unit for desalination of hardness
stabilized drinking water according to UK
drinking water regulations (free chlorine
not detectable), operating on the principle
of reverse osmosis.
Unit design
Stainless steel main frame housing the instruments
and controls.
Special inlet filter with 5 µm-filter
cartridge, high pressure pump low noise, multi-stage
centrifugal type, low energy spirally wound
modules with energy-efficient PA/PS composite
membranes in GRP vessels with inliner.
Valves such as sampling valves for feed water
and permeate (for each pressure vessel), inlet
solenoid valve/inlet diaphragm valve, valves
made of stainless steel to regulate the flow
rate of permeate, concentrate and concentrate
recirculation.
Pressure gauges for inlet and outlet pressure
pre-filter, pump pressure, operating pressure
and concentrate pressure, pressure switch
for monitoring the feed water pressure.
Flow meters for permeate, concentrate and
concentrate recirculation flow rate.
Conductivity measurement Permeate, temperature
compensated, measuring range 2-200 µS/cm.
Connection set for cleaning device, T-piece
for injection point, concentrate flushing
device.
Control cabinet with lockable main switch,
electrical switchgear for control of the high-pressure
pump and antiscalant dosing unit.
RO 1000 microprocessor control system for
fully automated monitoring and control of
the sys-tem with two line text display (16
characters per line) for display of operational
status, permeate conductivity, temperature,
operating hours, password-protected programming
of the operating se-quences 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 dis-plays 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. Compressed air (oil-free) 4-6
bar required (from UO 7000 AS onwards).
The units are designed for a maximum TDS
of 1,000 mg/l, a water temperature of 15°C,
a maximum colloidal index of 3 and free permeate
outlet. Under these conditions, the units
still reach design permeate flow after three
years of operation. The permeate recovery
depends on the raw water quality and the type
of pre-treatment. Optional Equipment
Surcharge for microprocessor control RO 5000
