As the world continues to focus on finding new
sources of drinking water, increasing attention has
been paid to the reverse osmosis (RO) process and,
in particular, seawater RO (SWRO). In this article
the authors discuss how proper pretreatment of seawater
before the RO process can have a significant
positive impact on the effectiveness of the SWRO
process as a whole.
This is the first study to conduct a side-by-side comparison
of membrane and conventional pretreatment
for SWRO. Utility managers will benefit from the
descriptions of the methodologies for testing and the
performance comparisons of different pretreatment
strategies. This information will become increasingly
valuable as more attention is focused on seawater as a
possible alternate water supply. Includes 21 references, tables, figures.
