Eimco-k.C.P.`s rotary pre-coat filter is a drum type clarification or polishing device. This is mainly used to clear out the difficult filtering and low solids slurries on a continuous basis. The process is done by the pre deposited bed of diatomaceous earth or similar material and all the slurry solids are removed on each revolution. Specially they are designed with air tight hoods. To give greater flexibility with "lathe prevision" movement the scrapper blade of drum driver operates independently.
