The flocculation process of the sludge is a combined process of electrolysis and power ultrasound. The flocculated sludge flows to the separator, which removes the flocs, before the dewatered sludge is pumped into the decanter. From the decanter the semi-dried sludge is let through a drying unit as final stage of the sludge treatment.

Sewage treatment is the process of removing contaminants from municipal wastewater, containing mainly sewage plus some industrial wastewater.Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safe enough for release into the environment.A by-product of sewage treatment …

After treatment of sludge in a sludge treatment reed bed system, recycling options for sludge are good as, among other routes, the sludge will be suitable for use as fertilizer on agricultural land.

Treatment and disposal of sewage sludge are major factors in the design and operation of all wastewater treatment plants. Two basic goals of treating sludge before final disposal are to reduce its volume and to stabilize the organic materials.

Seán Moran, in An Applied Guide to Water and Effluent Treatment Plant Design, 2018. Anaerobic Sludge Digestion. Sludge treatment and disposal can account for half of total sewage treatment costs. The commonest form of biological sludge treatment on large works is anaerobic digestion (AD), in which sludge is held in a mixed tank in the absence of oxygen.
