The EIMCO-K.C.P. String discharge RVDF system of endless strings or wires spaced about 13 mm 0.5 in apart pass around the filter drum but are separated tangentially from the drum at the point of cake discharge, lifting the cake off as they leave contact with the drum.
Once a full cake is built on the drum, the wastewater is pumped into the pan at a controlled rate. The vacuum sucks the water liquid through the drum and pumps it away. Suspended solids, precipitated metals, or de-emulsified fat, oil and grease larger than one-micron will accumulate on the filter cake
