The initial sludge is by gravity supplied directly to the filter-press (gravitation zone) or at first to the press filter belt gravity thickener and then to the filter-press. Cloth width sludge even distribution is provided by the special device called an automatic loader. 

After the gravitation zone sludge enters “wedge-shaped” zone and shearing compression zone where gradual moisture expression is being occurred. Subsequent sludge moisture reduction is occurred at the special device, which forms the enhanced pressure (supplementary compression zone). Compression pressure is being adjusted. Dehydrated sludge (cake) is being supplied by loader to a feeding box where it is being loaded on a dump trucks, carts etc. and removed to the ground. Belt flushing is accomplished under pressure through the framework-specific self-cleaning nozzles. Water supply for press filter belt flushing is being accomplished from the flushing pump. 

Applying the intake chutes flushing filtrate and water are being collected in a stainless steel underpan. It is foreseen the availability of separate press filter belt flushing filtrate and water collection. Dehydration process control is carried out by the control cabinet where control, signaling and display elements are located.
