Biofouling is one of the most common and severe problems in the operation of a reverse osmosis (RO) system. Unchecked, it causes significant operational problems such as frequent interruption, damage to the membranes, intense chemical and energy use, and regular cleaning-in-place (CIP) of the RO.
Dupont Water Solutions is launching a pre-treatment technology that efficiently eliminates the effects of biofouling in RO systems. Dupont B-Free solution is the result of a multi-year research and development effort that consists of a vessel-based media technology that offers a reliable, easy-to-use and sustainable solution. It is based on the ability of B-Free pre-treatment technology to create an instant and sustained biostatic environment for the downstream RO operations without the need for chemicals and resilient to upstream upsets.
B-Free pre-treatment is the solution designed for customers suffering from biofouling and looking for designing, building and operating reliable RO systems at an optimised cost of water and sustainability footprint. The technology enables a reduction of CIP frequency by up to 75 % and may double the RO membranes and cartridge filters’ lifetime. The B-Free customers will be able to achieve a low-touch and stable plant operation with up to 50 % lower operations downtime required.
