Water demineralization stations

Reverse osmosis units are designed for water demineralisation using the membrane technology. Unlike ionic water treatment methods, the process is carried out without the use of chemicals. Reverse osmosis systems remove ions, bacteria, viruses as well as pathogens from water. Sewage from RO units can be discharged into the sewage system without any problems and there is no need to neutralize it as in the case of chemical water demineralization stations.

Water demineralization stations are used in many applications requiring low concentrations of dissolved salts, e.g. in car washes, boiler rooms, hospitals, laboratories, catering, production of cosmetics and medicines or in humidifying systems.

Reverse osmosis is a process that makes it possible to produce demineralized water in an environmentally safe manner without the use of aggressive chemicals. Sewage (concentrate) produced on a continuous basis is also not harmful to the environment. Thanks to this technology, it is possible to eliminate up to 99.5% of dissolved salts.Typical applications of reverse osmosis are found in turbine power plants, production of potable and irrigation water from seawater (desalination). 

Demineralization – ultra-pure water

There are very high purity requirements of process water for various production applications. By combining the RO system with a continuous electrodeionization unit (EDI unit), ultra-pure water can be produced with a conductance of up to approximately 0.06 mS/cm (18 MΩ at 25°C). The developed EDI system uses ion-selective membranes and a special ion-exchange resin to produce clean water continuously. No chemicals are used in the EDI technology.
