Method

recommend the lowest dose meeting target NTU; flag the economic knee (within 10% of min turbidity)

Reference: APHA/AWWA/WEF Standard Methods (jar test); AWWA.

Recommendation is derived only from your measured jars, valid for the water quality at test time. Re-run when raw turbidity or season changes. Not a substitute for continuous plant optimisation.

Recommended operating dose: 30 mg/L (predicted settled ~3.5 NTU). Take it to the coagulant tool for kg/month.
