RE: Settling tank

Lisa, you may also want to look at the use of a hydrocyclone (either instead
of or in conjunction with the settling tank) 
for removing this material, since it should take dramatically less floor
space, and obtain a higher efficiency in separating 
the solid material from the wash water stream.  Of course, the final
selection will depend on residence time, particle size and 
density, etc, but it is worth considering.

as far as a local (to SW Ontario) supplier of said tanks and/or
hydrocyclones, you might try the Chemical Engineering Buyer's Guide, 
which is available online at  (though I had
problems connecting today) or Thomas' Register available at 
www.thomasregister.com.  The latter focuses on US suppliers, but many of the
listed vendors/manufacturers have Canadian distributors as well.

Hope this helps.
