Polymer Feed Rate of Dry Polymer Formula

Equation for calculate polymer feed rate of dry polymer is,

Polymer feed rate (lb/h) = (polymer dosage) × (dry sludge feed) / 2000 lb/ton
Polymer feed rate (gal/h) = polymer feed rate (lb/h) / [ (8.34 lb/gal) × (s.g.) × (% d concentration) ]

where,
s.g - specific gravity of the polymer solution
