S. Gangavarapu L. D. Benefield A. S. McAnally University of South Carolina Auburn University A pilot scale water hyacinth treatment system was constructed near a small Alabama town to investigate the feasibility of using this type of process as a low cost, easily implementable alternative for upgrading small community wastewater treatment systems in southern states. Design equations have been developed based on a series of multiple regression analyses using experimental data obtained from harvested and non-harvested treatment trains. The best predictive equations for effluent five-day biochemical oxygen demand concentration and effluent ammonia-nitrogen concentration were developed based on wastewater characteristics and operational parameters. These parameters include influent and effluent five-day biochemical oxygen demand concentration, influent and effluent ammonia-nitrogen concentration, hydraulic loading rate, organic loading rate, ammonia loading rate, pH, average water temperature and plant growth rate.
