Peristaltic pumps' simple, glandless, "straight through" construction, without valves, vanes or impellers, has clear advantages in handling viscous sludges which may contain rags or other solids which cause blockages. Their ability to impart minimal shear, combined with their high levels of volumetric accuracy when handling additives such as polyelectrolyte, is important for efficient flocculation and additive consumption.
Installing Watson-Marlow pumps can cut operating costs for feeding primary or thickened sludge to digesters or filter presses, and in primary tank auto-desludging.
To complete primary auto-desludging after digester treatment, the sludge goes to secondary storage tanks, where low-pressure peristaltic pumps dose polyelectrolytes before dewatering.
Watson-Marlow models are the industry's first choice at all stages of the process, in sizes from the 300 series, which is used for deodorising and pH control, for example, to the largest of our SPX models, which are widely used for heavy-duty transfer.

Watson-Marlow peristaltic pumps are ideal for metering the harsh and aggressive chemicals which are used in water purification, as well as transferring sludges. They offer huge operating savings over other pump types. Click here to see how Watson-Marlow and Bredel pumps integrate fully with the water treatment process.
