Sludge is a side product of several wastewater treatment stages like screening, DAF, biological treatment etc. Sludge dewatering is a process where wastewater sludge is reduced in weight and volume and separated into liquid and solid components. The amount of sludge depends on the type of wastewater treatment processes - the better wastewater is treated in all treatment steps, the more sludge is created in treatment process.
Sludge dewatering itself is not a wastewater treatment, it is a mechanical process to reduce wastewater sludge in weight and volume and separate into liquid and solid components. The most commonly used technologies for sludge dewatering are pressing and centrifuging.
The choice of sludge processing method depends not only on the volume of sludge generated but also on further treatment costs required for environmentally safe disposal because the dewatered sludge may contain contaminates that need to be treated separately.
