Profiting from Better Wastewater Treatment
Case Study
A leading anode manufacturer struggled to keep copper discharge levels below the 2.5 ppm regulatory limit using an outdated ferric coagulant. The inefficient process required excessive labor, consumed high amounts of chemicals, and produced iron-rich sludge that was costly to dispose of instead of recyclable. A thorough evaluation led to a streamlined solution centered on a more effective calcium-based coagulant, AquaPure Cal40, which significantly improved copper removal while reducing sludge contamination. A polymer flocculant was also introduced to enhance separation efficiency and optimize treatment.
With hands-on training for operators, optimized chemical dosing, and a refined system, the facility achieved consistent compliance while reducing operational effort. The improved process eliminated excess iron in the sludge, making copper recycling a profitable option instead of a cost burden. By cutting labor and waste disposal costs, the manufacturer transformed its wastewater treatment into a more efficient and profitable operation.
