Brackish Water Reverse Osmosis – Basic

MAK Water’s Brackish Water Reverse Osmosis – Basic (BWROB) plants are designed to treat ground/surface or industrial water with <5,000 mg/L of dissolved solids (TDS) and <5 mg/L of suspended solids (TSS), to achieve potable water quality. The standard treatment process involves pre-filtration (5 and 1 micron cartridge filters) and RO desalination. The MAK BWROB is designed to operate continuously until the permeate tank is filled, or pressurised feed water is unavailable.

The BWROB plants are pre-engineered products, designed for simple applications, where a high level of automation is not required and feed water quality falls within defined parameters. A pre-determined number of standard options may be added as required to suit feed water conditions and/or treated water quality requirements. MAK BWROB plants are available as skid mounted or containerised systems.

If you have specific requirements, contact us to discuss our custom designed desalination plants or ask about our hire options.
