Calculation of sludge dewatering capacity of belt filter ...

For the sludge dewatering system of the municipal wastewater treatment plant, the specific resistance of the sludge is controlled by (1 ~ 4) × 1012m / kg (the laboratory is determined by the r value to determine the more economical dosage) (1 ~ 3) × 1012m / kg (centrifugal dehydration r = (2 ~ 4) × 1012m / kg) for the belt filter press, the laboratory generally through the dosing sludge after the specific resistance r.

A review on sludge dewatering indices Water

In sludge management systems, after being pre-treated by thickening, digestion or conditioning, sludge is often dewatered before any further processing occurs, such as incineration, composting and landfill (Water Pollution Control Federation 1985).This will result in the reduction of sludge volume and, consequently, the cost of transportation (Feng et al. 2009).

Processing Wastewater Sludge Using Dewatering

The dewatering container itself has no moving parts. The waste is processed in the same unit in which it is hauled away and dumped, thus limiting the handling of the sludge. The dewatering box will give volume reductions in the 80% to 95% range depending on the percent solids in the sludge.
