Which Positive Displacement Pump Is Best For Wastewater ...

Centrifugal. 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.

Belt filter - Wikipedia

The belt filter (sometimes called a belt press filter, or belt filter press) is an industrial machine, used for solid/liquid separation processes, particularly the dewatering of sludges in the chemical industry, mining and water treatment.Belt filter presses are also used in the production of apple juice, cider and winemaking. The process of filtration is primarily obtained by passing a pair ...

Is a Belt Press or Plate and Frame Filter Press the Right ...

The belt press is most useful when a continuous operation is desirable. Typically a belt press produces between 18% and 25% solids by weight in the cake. Belt presses work by removing sludge onto two different dewatering belts where freestanding water molecules are separated from the sludge by gravity and are collected by a trough.
