Abstract:

The study established that rotary vacuum precoat filtration provides a means for dewatering sludges containing substantial amounts of finely divided, relatively impermeable solids. The work covers both bench scale and pilot plant testing to determine the possible applicability of the system to a variety of such sludges.
