Quantity of Volatile Solids Produced Each Day Calculator

Posted by Dinesh on

Use the simple wastewater and environmental protection calculator tool that helps you to calculate quantity of volatile solids produced each day online. The volumetric loading is expressed in lb/ft3 ( day.kg/m3.day). For high rate digesters, loading range from 0.10 to 0.35 lb/ft3.d (1.6 to 5.61 kg/m3.d).

Calculation of Volatile Solids Produced Quantity

Yield coefficient (lb VSS/lb BODL) :
BODin (lb/d) :
BODout (lb/d) :
Endogenous coefficient (kd) :
Mean cell residence time [d] :
Volatile Solids Produced [lb/d (kg/d)] :


Px = Y[(BODin) - (BODout)] / 1 - kd?c

  • kd - endogenous coefficient (d1)
  • ?c - mean cell residence time (d)
  • BOD - Biochemical oxygen demand
  • Y - yield coefficient
  • Px - volatile solids produced
