Sewage Sludge Thickening Without the Use of Polymer Video
Different processes are used for wastewater treatment depending on the size of the sewage treatment plant. Flottweg decanters for thickening and dewatering sewage sludge are used in various stages of wastewater treatment. Thickening sewage sludge is one of the most important steps treating wastewater. Thickening means to concentrate the surplus sludge produced in the biological stages, before it is pumped into the digestion tower. The sludge volume is reduced by 90 to 95% in this process. The Deggendorf sewage plant is concentrating the surplus slurry without the use of polymer. This is a unique way of thickening sewage sludge, made possible by the Flottweg OSE Dekanter and saves the sewage plant money.
