Organically modified clays have proved to be an effective
and economical medium for removing small amounts of
oils from water. Organoclays are also a good prepolisher
for activated carbon, membranes, reverse osmosis units, and ion
exchange resins - media that tend to become blinded by oil
droplets that coat the openings.
Although organoclays have been used successfully for many
years, little data existed about the optimum chemical conditions
for their use or the best organoclay for a particular application.
Tests conducted on some 50 oils of all classifications found that
organoclays are superior to activated carbon for oil removal and
that cationic organoclays are more effective for removal of the
more-polar crude oils.
Because water is an increasingly rare commodity, more
priority and attention have focused on conserving and recycling
water. Organoclays help achieve that goal by removing oil and
grease at less cost than carbon and with minimal
maintenance. Includes 6 references, table, figures.
