Brackish Water Reverse Osmosis – Basic

MAK Water’s Brackish Water Reverse Osmosis – Basic (BWROB) plants are pre-engineered products, designed to suit simple applications where a high level of electrical instrumentation and controls is not required, and the feed water quality falls within the parameters defined in this data sheet.

The standard treatment process involves pre-filtration (5 and 1 micron cartridge filters) and RO desalination. The BWROB is designed to operate continuously until the permeate tank is filled, or feed water is unavailable.

The BWROB is available with a pre-determined number of standard options and is supplied with a generic documentation package.

If you have specific requirements,2ManBetX登陆 to discuss our custom designed desalination plants or ask about ourhire options.
