Engineering Cladophora wastewater eutrophication nutrient removal algae Eutrophication of natural waters has become a problem throughout the world and locally in Lake Erie. In order to stop eutrophication, nitrogen and phosphorus levels entering natural waters must be decreased. One manageable source of nitrogen and phosphorus to the environment is wastewater treatment. Batch experiments were carried out using the alga Cladophora glomerata to determine its growth rate in wastewater, nutrient removing potential in wastewater, and biofuel potential. Trials were conducted using an optimized medium, a synthetic wastewater medium, and an effluent wastewater sample. Specific growth rates were highest in the effluent wastewater sample, 0.115 grams algae growth per grams algae per day (day-1) and 0.159 day-1. Nutrient concentrations in wastewater grown Cladophora glomerata were determined to be approximately 0.0136g phosphorus per dry weight (DW) gram of algae and 0.0415 g nitrogen per DW gram of algae. Predicted methane yield from Cladophora glomerata was calculated at 0.289 – 0.578 L CH4/g DW algae. A proposed Cladophora glomerata wastewater nutrient removal system was designed based on these parameters and compared to a conventional nutrient removal system. It was concluded that the algal system could be potentially viable for wastewater treatment plants with flows up to 1.0 million gallons a day (MGD). For larger facilities, the estimated initial capital costs of the algal treatment system and associated land requirements were far too significant. 2012-09-27 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1336488346 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1336488346 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
