To help overcome the repeated blockage of diaphragm pumps when dosing ferric sulphate at wastewater treatment plants, a number of Welsh Water sites now feature Qdos 30 peristaltic pumps from Watson-Marlow Fluid Technology Group (WMFTG).
With ever-tightening Water Framework Directive (WFD) standards, phosphorus limits are under close scrutiny. To reduce the ingress of phosphorus through municipal wastewater treatment plants, chemical coagulation is required.
Designed as a drop-in replacement to diaphragm pumps, Qdos peristaltic metering pumps are designed to offer long maintenance intervals, reducing the impact of process downtime and lowering total cost of ownership. They also aim to cut chemical cost through higher accuracy (±1%) metering.
