Sludge Weight Flow Rate Formula

Equation for calculate sludge weight flow rate is,

W_s = [ (V) × (ρ) × (s.g.) × (% solids) × (60 min/h) ] / 7.48 gal/ft³

• V = volume flow rate of sludge feed
• s.g. = specific gravity of sludge
• % solids = percent solids expressed as a decimal
• ρ = density of water, 62.4 lb/ft³ (994.6 kg/m³)
• W_s = weight flow rate of sludge feed
