The unit has a large flocculation tank with a variable speed mixer which allows the sludge and polymer solution to be thoroughly mixed. This flocculation process is critical to the dewatering process as it helps to separate the water and the sludge; the sludge then forms into small popcorn size balls in the water.

Solid Liquid Separation – Greendex
Solid Liquid Separation – Greendex

The pre-thickener performs the initial solid/liquid separation stage, taking sludge solids concentration from 0.5-3% up to 5-15 %. The dewatering in the press occurs firstly in the low pressure zone, then in the wedge zone and finally in the high pressure zone where the filter cake is compressed between the perforated cylinder cloth and the main cloth.
