RAS Pump
RAS Pump
WILO offers efficient pumping solutions for Return Activated Sludge (RAS) applications in biological wastewater treatment systems. RAS pumps recirculate settled activated sludge from secondary clarifiers back to aeration tanks, maintaining the required biomass concentration for effective treatment performance.
WILO end-suction and submersible sewage pumps deliver reliable sludge handling, anti-clog operation, and continuous-duty performance. Engineered to handle solids-laden wastewater, these pumps ensure stable recirculation while minimizing maintenance requirements. WILO solutions help optimize biological treatment efficiency, improve process stability, and support long-term reliability in industrial and municipal effluent treatment plants.
