Sludge Thickener Feed Pump

Sludge Thickening - an overview | ScienceDirect Topics

Each thickener should have a dedicated feed pump of the progressive cavity type. Desludging can be initiated by sludge blanket level and terminated after a pre-set time, or when the solids concentration in the discharge measured in the outlet pipe falls to a pre-set value.

Sludge Pumps & Wastewater Grinders | Vogelsang USA

In this way, using a single pump, wastewater and sludge can be simply recirculated between tanks and sump or fecal matter removed from disposal vehicles or tankers filled with sewage sludge. Since delivery rate is proportional to speed, the pump capacity can simply be variably adjusted via the variable frequency drive while the delivery rate remains the same.

Which Positive Displacement Pump Is Best For Wastewater ...

Centrifugal pumps are good for low viscosity sludge with very little solids. This type of pump will generate far less pulsation than the positive displacement pumps that make up the remainder of this list. Centrifugal pumps do have a high shear rate, unfortunately. As you probably know, imparting shear on sludge is counterproductive.
