With an expanding market worldwide for advanced polymer dosing systems, the introduction of the Qdos 60 PU peristaltic pump from Watson-Marlow Fluid Technology Solutions (WMFTS) means operators can now deploy efficient, safe, and reliable polymer metering at any water or wastewater treatment plant.
Polymers are used mostly in coagulation and dewatering applications in the sludge treatment process. Dewatering sludge minimizes sludge bulk, which can reduce the cost associated with storage and disposal by up to 75 percent.
There are strong regulatory drivers globally for efficient sludge dewatering.
Accurate and reliable metering of polymers in the sludge dewatering process is essential to ensure it is managed properly.
The Qdos 60 PU offers precise and repeatable flows for many hard to handle fluids, including viscous flows and aliphatic hydrocarbons, at linear flow rates of up to 60 l/h and pressures of up to 5 bar. The pump provides excellent compatibility for complex polymers such as polyacrylamide (PAM) and other flocculants and coagulants used in wastewater treatment.
The Qdos 60 PU is optimized for low-shear, gentle pumping to protect polymer chains and maintain product integrity. As with the Qdos 20 PU, it uses an aliphatic hydrocarbon-resistant tubing material, enhancing chemical compatibility in peristaltic pumps.
Peristaltic pumps have notable advantages over diaphragm pumps in PAM metering applications, including enhanced accuracy and reliability. There is no need for diaphragms, valves, or seals that risk clogging.
The only part of the pump that ever requires replacing is the patented ReNu pumphead. The ReNu pumphead offers repeatable, accurate flow rates and lasts longer for tough applications in the field. It takes less than a minute to replace the ReNu pumphead — a new pumphead is a new peristaltic pump, ready to serve again.
