BIOGAS FROM A COVERED LAGOON DIGESTER

Baseline operating parameters of the covered lagoon digester ;
  1. LAGOON DIGESTER VOLUME - Based on the length, width and depth of the lagoon as measured in meters
  2. INFLUENT FLOWRATE - Rate of the influent entering the lagoon as measured in liters
  3. HYDRAULIC RETENTION TIME - Volume of the lagoon divided by the daily influent flow as measured in days
  4. AVERAGE BIOGAS PRODUCTION - Average production of biogas as measured in cubic meters per day
  5. METHANE CONCENTRATION - Biogas concentration as measured in percent by volume
  6. LAGOON DIGESTER TEMPERATURE - Average temperature of the lagoon contents as measured in degrees C
  7. INFLUENT COD CONCENTRATION - Chemical Oxygen Demand as measured in milligrams per liter
  8. EFFLUENT COD CONCENTRATION - Chemical Oxygen Demand as measured in milligrams per liter
  9. COD REDUCTION - Reduction in COD from influent to effluent as measured in percent
  10. TOTAL AND VOLATILE SOLIDS PERCENTAGE - Percent of dry solids in the influent and percent of organic solids in the dry solids
  11. INFLUENT AND EFFLUENT LAGOON pH
