Water treatment - HAP Car Wash

Reverse osmosis

Based on molecular separation, reverse osmosis allows highly pure water to be obtained, eliminating up to 99.5% of the salts it contains.

The process of reverse osmosis has replaced demineralization at power plants due to the much better features it offers, as indicated below.

Calcium, magnesium, iron, silica, manganese, barium salts, chlorides, in combination with carbonates, bicarbonates and sulphates are present in increasing quantities in water extracted from wells.
They cause scaling and blocking of cooling circuits, reduce heat transmission in steam generators, and cause the contamination of water tables.

While in demineralization, between the start and finish of the cycle, the water produced is increasingly saline, in a reverse osmosis plant the water produced always has low values (10-15 microS/cm).


  • No need for acids and caustic soda
  • Non-polluting
  • Lower labour cost
  • No need for calibration or control during operation
  • Easy to handle
  • Small size
