Pretreatment of Turkey Fat in Wastewater in Sand Bioreactors

Due to slow decomposition, typically fat, oil, and grease in wastewater is hard to treat. In this study, two types of sand bioreactors were set up to treat the wastewater. One set had varying depth of coarse sand while the other had varying depth of pea gravel. The results from the COD test indicate that the larger depth of pea gravel was able to trap the fat, oil, and grease from the wastewater better than the larger depth of coarse sand.
