KNIFE DISCHARGE FILTERS

KNIFE DISCHARGE FILTERS

They are essentially composed of a rotating drum, vacuum distributing system, tank, oscillating agitator and “cake” discharge device. The separated solids (so called “cake”) are uniformly dried and distributed over the outer surface of the filtration elements. Several devices can be used for the continuous discharge of the “cake” from the septum, depending to the characteristics of the treated slurry, the Clients’ specifications and needs and Tecniplant’s experience.
This filter is suitable for treating slurries which contain high quantities of easy-to-drain suspended solids. The cake is discharged by a fixed knife scraping against the rotating drum.
Tecniplant can advise Clients on the correct Filter’s size based on Client’s product to be treated.
