Dewatering belts should be designed for easy replacement with minimum downtime. Belt washing should occur daily after the cake is removed.

Replacement of filter belts is a common maintenance requirement. Filter belt life averages about 2,700 running hours, with a range of 400 to 12,000 hours.

A belt press operator is responsible for polymer mixing, dosing and monitoring usage, and observing the feed and cake several times per day, making adjustments as necessary. Rollers and
bearings require frequent lubrication.

It is important for the operator to keep records of all press performance parameters, including the volume of biosolids fed to the press, polymer dosage, and potassium permanganate or other chemical usage. A sample of the biosolids to the press, cake discharge, and filtrate should be taken at least once per shift and analyzed for total solids. At the end of each shift, the belt should be cleaned with high-pressure wash water. Labor is relative to plant size. A plant with a single belt press needs four to eight staff hours per day (including lab testing), whereas six to eight presses can be operated with eight to ten staff hours per day. Large plants use less operating effort per belt press. Highly automated systems reduce labor requirements, but require an instrumentation
specialist to maintain the system.
