Calculate and compare coagulant, flocculant, and pH correction chemical requirements for DAF and physico-chemical wastewater treatment.
Chemical dosing is often the largest operating requirement in DAF systems after energy. Optimising coagulant selection, polymer type, and pH correction can reduce Operating expenditure by 15-30%.
Systematic jar testing identifies the optimal coagulant type and dose for your specific effluent, often revealing 15-25% overdosing.
Matching polymer charge density and molecular weight to your solids profile improves flocculation and reduces polymer consumption.
PAC often outperforms alum at low temperatures and produces less sludge. Ferric chloride excels at phosphorus removal.
Flow-paced and feedback-controlled dosing systems prevent overfeeding during low-load periods and shock loads.
Automated coagulant and pH adjustment dosing skids with SCADA integration.
