Belt filter presses

The belt filter press is a machine consisting of belts and guiding rollers, by means of which the sludge is dewatered. Sludge turning ensures higher degree of dewatering in the gravity filtration zone of the machine. The dewatered sludge (cake) falls out at the end of the belt, and water must be cleaned additionally. Two-stage type of the press is suitable for big plants. Main advantage of the belt filter press is lower noise level. For small plants this solution is inconvenient due to higher operation requirement, lower cake to filtrate ratio, and larger built-up area.
The decanter centrifuge is not demanding for operation. Operating costs are not increased by wash water, without which the belt filter presses cannot work.
