| Abstract | Over 50 experiments were performed on various wastewater treatment processes at a 200 gpm facility over a 20 month period. Major processes tested included chemical pre-treatment, activated sludge, plastic media trickling filters, deep tank aeration, and activated sludge disposal. Trickling filters were determined to be unsuitable, and the decision was made to design the full scale plant as an activated sludge plant that could be arranged in both the conventional and step feed process variations. The plant design should include deep tank aeration, and phosphate removal by injection of steel pickling liquor. Sludge disposal units investigated included vacuum filtration, centrifugation and filter pressing, but further research was deemed necessary before the selection of a single unit. 87% phenol reduction was achieved in the biological oxidation process, somewhat below the 97% removal required. This lower removal percentage indicated the necessity of further investigations. |
