Biofilms are being used more frequently to aid in the cleansing of wastewater through oxidation of organic particles and nitrification of ammonium. This study focused on the biological treatment of wastewater through the use of biofilms. Six biofilms were grown in a reactor tank; four were on nylon mesh frames and two were on plastic membranes, one aerated and one anaerobic. The reactor tank consisted of 48.5 liters of diluted wastewater which was circulated and oxygenated to imitate a river. Analytical testing techniques such as the TOC test, the Ammonium Nessler test, and UV-Visible Spectrometry were used to determine the components of the diluted wastewater and to monitor the efficiency of biofilms in wastewater treatment.
