Low pressure systems

Reverse osmosis system with high retention

As a rule, our standard reverse osmosis systems of the LE type (LE = low energy, low pressure systems) are used for the desalination of softened drinking water.

Depending on the service, application, or location of the customer, various versions are offered:

  • 100-300 l/h in a control cabinet or wall cabinet
  • as an independent frame system with standing modules (100-1,200 l/h) or lying modules (1,500-9,000 l/h).
  • as a small frame stand system (1,500-4,000 l/h with standing modules).
  • in the glass-doored control cabinet (600–2,000 l/h).

The reverse osmosis systems are equipped as standard with:

  • Special prefilter
  • High-pressure stainless steel pump
  • High-performance winding modules
  • Float flowmeters for permeate and concentrate
  • Pressure gauges for inlet pressure, pump pressure, operating pressure, and concentrate pressure
  • Conductivity measurement in the permeate
  • Automatic flushing solenoid valve

For convenient control and automation, a small PLC with a display is available for the smaller sizes, or a PLC control with a 4.3“ touch panel is available for the larger systems. The controller is equipped with extensive functions such as:

  • Automatic start/stop via level sensors
  • Flushing on demand (timer if system is turned off)
  • Conductivity monitoring in the permeate
  • Pump that can be adjusted for dry running protection

Among other things, the following functions can be optionally selected:

  • Hardness control in the inlet
  • Concentrate deficiency monitoring
  • Permeate rejection or recycling
  • Electronic flow and pressure measurement
  • Anticalant dosing
