Environmental water and wastewater applications

For decades, Watson-Marlow Fluid Technology Group has helped water and wastewater treatment plants safeguard end-product quality, reduce cost of ownership, and minimize risk.

Our peristaltic pumps have no valves, diaphragms, rotors, stators, universal joints or lobes to fail. The risk of siphoning and gas locking, common in diaphragm pumps, is eliminated. They’re simple to operate, accurate, self-priming and capable of being run dry. This results in pumps that deliver:

accurate, contamination-free metering and dosing
reliable handling of slurries, viscous, abrasive and corrosive fluids
significantly lower total cost of ownership

The combination of the right products, supported by a global network of experienced support, is the reason leading water engineers turn to Watson-Marlow Fluid Technology Group to help them meet today’s challenges.

Watson-Marlow pumps in environmental applications

Sludge transfer and sludge feed

Bredel hose pumps reduce overall operating costs from reduced downtime and the elimination of ancillary costs when feeding primary or thickened sludge to digesters or dewatering devices like centrifuges and filter presses.

Other applications include belt filter press feed, centrifuge feed, plate and frame press feed, gravity belt thickener feed and discharge, septage, WAS (waste activated sludge) and RAS (returned activated sludge).

With no rotors, stators, lobes, discs, ball checks or seals to wear out, Bredel pumps are able to meet the most demanding sludge applications.

Suction lift capability of up to 9.5 meters
Dry running and self-priming
Ideal for high viscosity and shear sensitive product
No seals, ball-checks, diaphragms, glands, immersed rotors, stators or pistons to leak, clog, corrode or replace
Handles abrasive slurries, corrosive acids, gaseous liquids
No slippage, allowing true positive displacement for accurate and repeatable metering
No ancillary equipment, check valves, sealing water flush systems or run-dry protection required
Fully reversible to blow out suction and drain lines safely
