Brackish Water Reverse Osmosis - 50 (BWRO-50) 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 BWRO is designed to operate continuously until the permeate tank is filled, or feed water is unavailable.
The BWRO is available with a pre-determined number of standard options and is supplied with a generic documentation package.
