The simple glandless, "straight through" construction without valves, vanes or impellers, has clear advantages in handling viscous sludges liable to contain rag type or other solids which cause blockages, while the ability to impart minimal shear, combined with the high levels of volumetric accuracy when handling additives such as polyelectrolyte, is important in terms of both efficient flocculation and additive consumption. Reduced operating costs can be achieved by the installation of Watson-Marlow Bredel pumps in the feeding of primary or thickened sludge to digesters or filter presses, and in primary tank auto-desludging. To complete primary auto-desludging, following digester treatment, the sludge goes to secondary storage tanks, where polyelectrolytes are dosed by low-pressure peristaltic pumps prior to dewatering.
