Abstract
This dissertation discusses two Bio-Tower applications in wastewater treatment in the Village of Minoa for removing Chemical Oxygen Demand (COD), Ammonia Nitrogen (NH3 -N), and Total Phosphorus (TP). The Laboratory Benchtop Bio-Tower System and the Packed Bio-Tower System can effectively remove 60% to 80% of COD and over 90% of NH3-N in wastewater from the primary clafier effluent under various feeding rates. The Bio-Tower’s ability to remove TP was not significant. For the Laboratory Benchtop Bio-Tower System, five out of nine results showed that the removal efficiency was under 20%. In another Laboratory Benchtop Bio-Tower System test was done by pre-running the system with diluted cow manure indicated that the system could remove 60% to 80% of TP. This study also found the four-parameter logistic regression model can best describe the Chemical Oxygen Demand (COD), Ammonia Nitrogen (NH3 -N), and Total Phosphorus (TP) concentration change over time for both The Laboratory Benchtop Bio-Tower System and the Packed Bio-Tower System under various feed flow rate.
