BW-M

The BW-M range comprises medium-sized units for the production of drinking water. They are designed to desalinate brackish water with a salinity of up to 8,000 mg/l. In addition to drinking water abstraction, the systems can also be used to desalinate potable water to create pure water. Minerals and many other unwanted substances, such as chemicals, bacteria, viruses and heavy metals, are also removed from the water.

The BW-M are compact units mounted onto one or two frames. They are supplied ready for use, so installation and commissioning can take place on site within a very short space of time.
