Carbon Limitation In Periphytic Algal Wastewater Treatment Systems, Brandon J. Furnish

Theses and Dissertations

As global eutrophication poses an ever increasing threat to water quality new techniques must be implemented to improve the sustainability of natural resource consumption. Wastewater treatment facilities (WWTF) are designed to destroy pathogens, remove particulates, lower oxygen demanding substances, and reduce nutrients from influent waste water to avoid the degradation of receiving waters. WWTF are generally effective, however they are mostly inadequate at removing nutrients. When wastewater derived nutrients such as nitrate and phosphate are discharged to receiving waters, they stimulate algal blooms. Algal blooms can reduce dissolved oxygen, block sunlight for submerged aquatic plants, and render state waters unusable …
