Reverse Osmosis Systems


  • Permeate capacities from 100 to 30,000 l/h standardized larger services on request
  • with energy-saving low-pressure membranes or with high-retention membranes
  • various options standardized

Low Pressure Systems

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.

Systems with high retention

The reverse osmosis systems of the HR type (HR = high rejection = high retention) correspond to the previously described reverse osmosis systems of the LE type with the difference that other membranes are used. By using special membranes with high retention, the desalination rate can be increased from about 97.0% to about 98.5%.

Permeate-stepped Systems

The permeate-stepped reverse osmosis systems are 2-stage systems that are used for the extensive desalination of softened drinking water. Since high-retention membranes are used and the plant is designed in 2 stages, high desalination rates of > 99% can be achieved.

Back pressure Systems

The reverse osmosis systems for operation with permeate back pressure (PGD) are used for desalination of softened drinking water if there is a back pressure in the permeate line. The systems are controlled via a pressure sensor in the permeate, i.e. production is started or stopped when the on or off pressure is set.

Combined Systems (with Softening)

The combined plants are compact plants with a softening plant for pre-treatment and a reverse osmosis plant for desalination of drinking water.
