Effect of dewatering aid dosage in electroforced sedimentation

Nowadays wastewater treatment plants are producing huge amount of sludge. The water content of the traditionally dewatered sludge, resulting from drying beds, centrifuges, vacuum filters, screw press filters and pressure filters, remains a critical factor affecting the choice of transportatio...

The water content of the traditionally dewatered sludge, resulting from drying beds, centrifuges, vacuum filters, screw press filters and pressure filters, remains a critical factor affecting the choice of transportation vehicles, transportation costs, and suitability of sludge for incineration.
