# Quantity of Volatile Solids Produced Each Day Calculator

Posted by Dinesh onUse 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/ft^{3} ( day.kg/m^{3}.day). For high rate digesters, loading range from 0.10 to 0.35 lb/ft^{3}.d (1.6 to 5.61 kg/m^{3}.d).

## Calculation of Volatile Solids Produced Quantity

### Formula:

P_{x} = Y[(BOD_{in}) - (BOD_{out})] / 1 - k_{d}?c

- k
_{d}- endogenous coefficient (d^{–1}) - ?
_{c}- mean cell residence time (d) - BOD - Biochemical oxygen demand
- Y - yield coefficient
- P
_{x}- volatile solids produced
