Water & Wastewater Treatment

Industrial water and wastewater treatment systems must move chemically aggressive, particulate-laden, and continuously circulating fluids without failure. Whether it's effluent treatment plants, sewage handling, packed-tower scrubbers, or cooling water circuits, the cost of pump downtime is measured in compliance fines and unplanned shutdowns. Weltech's wastewater pump range is engineered for exactly this duty profile — corrosion-resistant materials, non-clog hydraulics, and seal options designed to withstand abrasive solids and acidic chemistries. From municipal STPs to industrial ETPs and gas scrubbing duties, our pumps deliver the material compatibility and uptime that keep treatment systems compliant around the clock. TYPICAL APPLICATIONS • Sewage Treatment Plants (STP) — influent transfer, sludge recirculation, return-activated sludge • Effluent Treatment Plants (ETP) — equalisation tank transfer, neutralised effluent discharge, sludge dewatering feed • Packed tower & venturi scrubbers — acidic and alkaline scrubbing liquid circulation • Cooling towers & RO pre-treatment — make-up water transfer, side-stream filtration
