sludge thickening tanks

Sludge thickening tanks are used to reduce the volume of excess sludge from WWTPs and serve as an intermediate step before further treatment (stabilization, dewatering).Sludge thickening tanks are implemented in various design configurations, most commonly as circular tanks with central inlet and peripheral outlet. They are simple, operationally reliable, and highly cost-effective, representing a proven solution for sludge handling at wastewater treatment plants.

They can be designed as stainless steel / carbon steel tanks or reinforced concrete tanks with the required technological equipment. Their design provides uniform inlet distribution, calm hydraulic conditions for sedimentation, and efficient separation of supernatant in the upper part of the tank.
