Municipal WWTP PAC Dosing Upgrade
Mechanical diaphragm pumps with online turbidity monitoring cut chemical consumption by 15%.
Key Metric
-15%
Chemical use
Challenge
This 50,000 m³/d plant dosed PAC manually by experience — high chemical use and fluctuating effluent phosphorus with compliance risk.
Solution
Mechanical diaphragm pumps dose proportionally to influent flow, with online turbidity closing the loop for true demand-based dosing.
Results
- PAC consumption down 15%
- Stable phosphorus compliance, 60% less fluctuation
- Inspection workload halved
