Thickening - Lenntech

Sludge treament A volume reduction of approximately 30 – 80 % can be reached with sludge thickening before a further treatment. At smaller wastewater treatment plants, where the sludge is driven off regularly, thickening usually takes place directly in the sludge storage tank.


treatment plant where they are treated in an active sludge process capable of purifying about 21,000 m³ of effluent per day. Sludges from primary sedimentation and thick-ener 1, from barking water thickener and bio sludge thickener are processed together, primary sludge and bio sludge making up the greatest volume. Figure 1.


It is also very easy to concentrate this type of sludge with a static thickening step just befo-re dewatering. The drawback is that this sludge ferments very easily. 1.2.2.
