DUPONT’S<br />
B-FREE PRE-<br />
TREATMENT<br />
TECHNOLOGY<br />
for reverse osmosis installations<br />
DuPont has launched a new B-Free<br />
pre-treatment technology that can<br />
be used to eliminate the effects of<br />
biofouling in reverse osmosis (RO)<br />
systems, which, in turn, reduce<br />
operation costs and improve plant<br />
uptime and reliability.<br />
Biofouling is one of the most common<br />
and severe issues in the operation of<br />
a RO system. If unchecked, it might<br />
cause operational issues such as<br />
frequent interruption, damage to the<br />
membranes, intense chemical and<br />
energy use, and regular cleaning-inplace<br />
(CIP) of the RO.<br />
The DuPont B-Free solution consists<br />
of a vessel-based media technology<br />
that offers a sustainable solution. It<br />
is based on B-Free pre-treatment<br />
technology ability to create an “instant<br />
and sustained” biostatic environment<br />
for the downstream RO operations<br />
without the need for chemicals and<br />
resilient to upstream upsets.<br />
The solution is designed for operators<br />
facing issues on biofouling and are<br />
looking for designing, building and<br />
operating RO systems at an optimised<br />
cost of water and sustainability<br />
footprint. According to DuPont,<br />
the B-Free technology enables a<br />
reduction of CIP frequency by up<br />
to 75%, and may double the RO<br />
membranes and cartridge filters<br />
lifetime. Furthermore, the B-Free<br />
customers will be able to achieve a<br />
low-touch and stable plant operation<br />
with up to 50% lower operations<br />
downtime required, the company<br />
added.<br />
Nanette Hermsen, global marketing<br />
and strategy director for DuPont<br />
<strong>Water</strong> Solutions, said: “B-Free<br />
pre-treatment is a breakthrough<br />
technology that effectively eliminates<br />
biofouling, and enables a significant<br />
improvement in plant reliability. As<br />
a result, this new technology will<br />
provide RO plant operators the<br />
ability to eliminate this troublesome<br />
and costly occurrence in RO<br />
systems.”<br />
DuPont B-Free pre-treatment<br />
technology is now available<br />
globally. It is one of the several<br />
innovations DuPont has introduced<br />
to help decrease the economic and<br />
environmental cost of water treatment<br />
to help combat water scarcity, and<br />
is aligned with the United Nations’<br />
Sustainable Development Goals for<br />
2030.<br />
“With this new technology, DuPont<br />
continues demonstrating innovation<br />
leadership and commitment to solve<br />
customer water challenges,” Gary<br />
Gu, global innovation and technology<br />
leader at DuPont <strong>Water</strong> Solutions,<br />
concluded.<br />
