Normal discharge of oil into a sump was not of
great concern in the past, but, with the present
environmental programs, removing oil from water
in sumps and other areas has become important
One method of removing the oil is the use of an
oil-absorbent material in pillow form. When
placed in a sump, the pillows float and absorb oil
as it comes to the surface. As it is not a fixed
system like a skim installation, it can also be
readily used in areas where accidental oil
contamination develops. The fact that
maintenance equipment costs are minimized
also makes this approach attractive. In large
sumps where sump discharge and oil
contamination is great, economics may dictate a
skim system, in which case oil-absorbent
materials could still be valuable as a supplement.
There are some excellent oil-absorbent materials
available. Two products in this category are:
1. Dica-SorbTM.- Detailed information and
