A dewatering screw press is a screw press that separates liquids from solids. A screw press can be used in place of a belt press, centrifuge, or filter paper. It is a simple, slow moving device that accomplishes dewatering by continuous gravitational drainage. Screw presses are often used for materials that are difficult to press, for example ...
Rotary vacuum drum filter (RVDF), patented in 1872, [2] is one of the oldest filters used in the industrial liquid-solids separation. It offers a wide range of industrial processing flow sheets and provides a flexible application of dewatering, washing and/or clarification. A rotary vacuum filter consists of a large rotating drum covered by a ...
The sludge is sometimes passed through a so-called pre-thickener which de-waters the sludge. Types of pre-thickeners include centrifugal sludge thickeners, [3] rotary drum sludge thickeners and belt filter presses. [4] Dewatered sludge may be incinerated or transported offsite for disposal in a landfill or use as an agricultural soil amendment. [5]
