Abstract |
This study demonstrated the feasibility of using plastic media in a stage system to achieve biological nitrification of municipal effluents. The secondary effluent from the Midland, Michigan, wastewater treatment plant was dosed to a pilot scale trickling filter containing plastic media. Consistent nitrification was obtained under both summer and winter conditions. Net cell growth was minimal, and the filter effluent could be directly filtered by tri-media filtration. The tri-media filter also served as a denitrification system when methanol was added to the nitrified effluent ahead of filtration. Significant changes were noted in the operational characteristics of the tri-media filter. |
