UO-D 1500 CD

Reference: 5110010197

Description:Ready-to-connect system including pre-treatment for desalination of drinking water according to drinking water regulations (free chlorine not detectable).

Due to integrated water pre-treatment components such as pre-filter, backflow preventer, duplex water softener and limitron hardness monitoring unit a piping on site is not necessary. Only 4 connections required (drinking water, permeate, waste water and mains connection). Continuous production of permeate possible.

Benefits

Unit design

  • Stainless steel base frame.
  • Prefilter with 100 μm-filter cartridge and two pressure gauges,
  • Pipe separator BA according to EN 1717 and DIN 1988-100,
  • Water meter controlled duplex softener installed on a frame, brine tank to be installed on the floor.
  • Hardness monitoring unit limitron for continuous monitoring of feed water hardness, in case of hard water the reverse osmosis shuts down.
  • Special inlet filter with 5 μm-filter cartridge and two pressure gauges filled with glycerin,
  • Low energy spirally wound modules with energy-efficient PA/PS composite membranes in GRP pressure vessels.
  • Valves such as sampling valves for feed water and permeate, inlet solenoid valve, stainless steel valves to regulate the flow rate of permeate, concentrate and concentrate recirculation flow, permeate check valve for each pressure vessel.
  • Pressure sensors for pump feed pressure, operating pressure and concentrate pressure.
  • Flow sensors for permeate, concentrate and concentrate recirculation flow rate.
  • Conductivity measurement of permeate with temperature compensation.
  • Screw connection for manual cleaning unit.
  • Control cabinet with lockable main switch, electrical switchgear for control of the high-pressure pump.
  • Unit completely wired and pre-assembled and ready for installation. Electrical equipment in accordance with VDE 0100 part 600, VDE 113 part 1.

Microprocessor control RO digital

  • for fully automatic monitoring and control of Reverse Osmosis Unit.
  • Process visualization with central display of operational status and data (analogue und digital values ) and hours of operation on 4-line, backlit LCD text display. Simple menu-driven operation of the controller with 6 buttons.
  • Automatic logging of relevant operating data (analogue and digital data, 1960 data sets), storage interval programmable.
  • Highest operational safety due to adjustable alarms and limits of the operating parameters with selectable system response.
  • Operating conditions: permeate production, permeate rejection / recirculation, concentrate displacement / flushing, intermittent flushing when system is idle, shutdown by an external signal.
  • Analogue inputs: permeate conductivity (temperature compensated) permeate temperature, feed water, operating and concentrate pressure, flow rates of permeate and concentrate, calculated feed water flow, 2 additional programmable analogue inputs (e.g. for pressure, flow, level measurement).
  • Digital Inputs: RO-unit start, RO-unit stop, hard water /motor protection, external stop, 3 universal inputs (free configurable)
  • Analogue outputs: 2 universal outputs 4-20mA, e.g. for DDC.
  • Digital outputs: high-pressure pump, valve outputs 3x (24 VDC) for example for feed water, concentrate flushing, permeate rejection or recirculation, collective fault indication as a floating changeover contact, universal output.
  • LED indicators for power and fault, fault alarms as plain text in the display.
Footnotes The unit is 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 unit still reaches design permeate flow after three years of operation. The permeate recovery depends on the raw water quality and the type of pretreatment.
