Reverse osmose

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from drinking water. The pore-free reverse osmosis RO membranes can completely hold back dissolved ingredients with a molecular weight of less than 200 g/mol. Due to the very good retention capacity of dissolved salts, RO has long been a tried and tested membrane process and is already state of the art in sea and brackish water desalination.

Our reverse osmosis systems can be adapted to the various requirements for pure water quality and can also be used in two-stage operation. The membrane type is always determined after requirements. We use our many years of experience in the design of reverse osmosis system based on the water analysis, the optimal variant for the customer.
