High or Low Brackish Reverse Osmosis

• Brackish water is any type of water with total dissolved solids (TDS) levels in the range of 1,000 to 15,000 ppm. The majority of the world’s water is either brackish or saltwater.
• Sea Water Reserve Osmosis Plants (SWRO) plants are designed to treat water or moderate-salinity groundwater with between 10,000 ppm – < 38,000 ppm of dissolved solids (TDS) to achieve potable water quality.
• High-brackish reverse Osmosis (HBRO) plants are designed to treat water or moderate-salinity groundwater with between 1,000 ppm – <10,000 ppm max of dissolved solids (TDS) to achieve potable water quality.
• Low Brackish  Reverse Osmosis (LBRO) plants are designed to treat water, or moderate salinity groundwater, with between 1,000 – < 5,000 ppm max of dissolved solids (TDS) to achieve potable water quality.

Reverse Osmosis Plants by Biosystems

Biosystems’s Sea Water Reserve Osmosis Plants (SWRO) are designed to treat seawater, or high-salinity groundwater, containing less than 40,000 mg/L of total dissolved solids (TDS) and less than 30 mg/L of total suspended solids (TSS), to produce potable water. The standard treatment process involves auto backwashing membranes and cartridge filters, anti-scalant dosing to prevent membrane scaling, RO desalination and auto flushing, and clean-in-place (CIP) systems for membrane cleaning. Additional pre-RO and post-RO treatment steps may be added as required to suit various feed water standards and/or post-treatment treated water quality requirements. The Biosystems’s SWRO Plants are available in skid-mounted or configured as containerized systems.

A standard skid-mounted product line is available in sizes ranging from 60 to 400 kUSgpd (225-1500 cubic meters per day/(m3/d)), that can be modified and configured for outdoor applications, containerized settings, or installed in fixed indoor placements.  

The company has a standard line of 2800 m3/d trains which can be easily linked for larger systems.
