DuPont launches B-Free RO biofouling preventive pretreatment

DuPont B-Free

DuPont launched of a new pre-treatment technology that is designed to eliminate the effects of biofouling in reverse-osmosis (RO) systems to reduce operational costs and to boost plant uptime and reliability.

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 B-Free patent-pending 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 B-Free pre-treatment technology ability to create an instant and sustained biostatic environment for the downstream RO operations without the need for chemicals and resilient to upstream upsets.

DuPont 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 optimized cost of water and sustainability footprint. DuPont B-Free technology enables an important reduction of Clean-In-Place (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.

“B-Free pre-treatment is a unique breakthrough technology that effectively eliminates biofouling and enables a significant improvement in plant reliability. As a result, this new technology will provide reverse osmosis plant operators the ability to eliminate this troublesome and costly occurrence in RO systems,” said Nanette Hermsen, Global Marketing & Strategy Director DuPont Water Solutions.

With proven robustness and value, DuPont™ B-Free pre-treatment technology is now available globally. It is one of several recent innovations DuPont has introduced to help decrease the economic and environmental cost of water treatment to help combat water scarcity, and it is aligned with the United Nations’ Sustainable Development Goals for 2030.
