GENERALLY, BIOGAS ESTIMATES RANGE FROM 0.2 TO 0.4
CUBIC METERS PER KILOGRAM (M³/KG) OF COD (CHEMICAL
OXYGEN DEMAND) REDUCTION IN THE ANAEROBIC
DIGESTION PROCESS.

To calculate the potential biogas production given POME composition
concentrations:
a. Determine COD levels: Obtain relevant POME samples and measure
the COD in kilograms.
b. Estimate biogas production: Assume an average yield (e.g., 0.3
m³/kg COD).
c. Calculate total biogas: Multiply estimated biogas production per kg
of COD by the total COD content in POME (in kg).

To calculate the total biogas production, follow these steps:

1. Determine the COD levels: Use relevant POME samples and measure the COD
   in kilograms. COD is a measure of the amount of organic matter present in the
   POME.
2. Estimate biogas production: Assume an average yield, such as 0.3 cubic meters per kilogram (m³/kg) of COD. This is an average value used for estimation purposes, as the actual biogas yield may differ based on various factors.
3. Calculate the total biogas production: Multiply the estimated biogas production
   per kilogram of COD by the total COD content in POME (in kilograms). This will
   give you the total volume of biogas that can be generated from the given POME composition concentrations.

For example, let's say the COD levels of the POME sample are measured to be 1000 kg. Assuming an average yield of 0.3 m³/kg COD, the calculation would be as follows:

Total biogas = Biogas yield (0.3 m³/kg COD) x Total COD content (1000 kg)
Total biogas = 0.3 m³/kg x 1000 kg
Total biogas = 300 cubic meters of biogas
Therefore, based on this calculation, the total biogas production from the given
POME sample with a COD content of 1000 kg would be 300 cubic meters.
