Initial Weight of Oxygen given Weight of Oxygen Required Solution

STEP 0: Pre-Calculation Summary

Formula Used

Weight of initial oxygen = (Weight of oxygen*Volatile suspended solid weight)/(Volume of suspended solid*2.3)
W_i = (W_O2*VSS_w)/(VSS*2.3)
This formula uses 4 Variables

Variables Used

Weight of initial oxygen - (Measured in Kilogram) - Weight of initial oxygen means the oxygen which is already present in the solution.
Weight of oxygen - (Measured in Kilogram) - Weight of oxygen required to destroy the Volatile suspended solids.
Volatile suspended solid weight - (Measured in Kilogram) - Volatile suspended solid weight means weight of the vss.
Volume of suspended solid - (Measured in Kilogram per Second) - Volume of suspended solid as mass flow rate.

STEP 1: Convert Input(s) to Base Unit

Weight of oxygen: 5 Kilogram --> 5 Kilogram No Conversion Required
Volatile suspended solid weight: 5 Kilogram --> 5 Kilogram No Conversion Required
Volume of suspended solid: 3 Kilogram per Day --> 3.47222222222222E-05 Kilogram per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_i = (W_O2*VSS_w)/(VSS*2.3) --> (5*5)/(3.47222222222222E-05*2.3)

Evaluating ... ...

W_i = 313043.47826087

STEP 3: Convert Result to Output's Unit

313043.47826087 Kilogram --> No Conversion Required

FINAL ANSWER

313043.47826087 ≈ 313043.5 Kilogram <-- Weight of initial oxygen

What is volatile solids ?

Volatile solids are a substance that can easily transform from its solid phase to its vapour phase without going through a liquid phase.The amount of volatile solids in wastewater is frequently used to describe the strength of the waste. The more volatile solids present in wastewater, the stronger that wastewater is.
