Brackish Water Reverse Osmosis

MAK Water’s Brackish Water Reverse Osmosis (BWRO) plants are designed to treat ground/surface or industrial water with <5,000 mg/L of dissolved solids (TDS) and <30 mg/L of suspended solids (TSS), to achieve potable water quality. The standard treatment process involves pre filtration (auto-backwashing multimedia filters and cartridge filters), anti-scalant dosing to prevent membrane scaling, RO desalination and a CIP system for membrane cleaning.

Additional pre-RO and post-RO treatment steps may be added as required to suit feed water conditions and/or treated water quality requirements. The MAK BWRO 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.
