Removal of Butterfat COD and BOD5 in Inoculated Sand Columns

While investigating the feasibility of the biodegradation of butterfat using sand bioreactors, the study found that there was a high degree of COD and BOD5 removal. Measuring the ATP determined the accumulation of biomass in the sand bioreactors. When supplemental detergent was added to the wastewater, an increased amount of biomass was able to accumulate in the sand bioreactors. This suggested improved contact between the microorganisms and the butterfat.
