Use the simple aerobic digester calculator tool to calculate the digested sludge volume for your wastewater problems.

Digested Sludge Volume Calculation

Weight of sludge [Ws] (lb) (kg) :
Density of water [ρ] (62.4 lb/ft3) (994.6 kg/m3) :
Specific gravity of digested sludge [s.g.] (assume s.g. = 1.03) :
Percent solids expressed as a decimal (%) :
Sludge volume [V] (ft3) (m3) :

Formula:

V = (Ws) / ((ρ) × (s.g.) × (% solids))

where,
  • Ws = weight of sludge
  • ρ = density of water
  • s.g. = specific gravity of digested sludge
  • % solids = percent solids expressed as a decimal
  • V = sludge volume
