Abstract
Water with excessive nutrients are continuously released into water bodies, the resulting eutrophication causes public health, environmental, and economic problems. Phosphorus (P) impairment of fresh surface waters is a major concern in the USA and worldwide. The aim of this study is to use a bench scale P removal system that utilizes electrocoagulation (EC) to address this water quality problem. This study examined the effects of treatment parameters (initial pH, initial conductivity, power input, and initial P concentration) on the ability of the EC process to remove P in solutions with initial P concentrations less than 2Â mg/L. It also investigated the ability of EC to reduce concentrations of P in surface water and treated wastewater. P concentrations in phosphate solutions, surface water, and wastewater effluent were reduced by 99% in under 60Â min. The removal efficiency was demonstrated to be directly proportional to the conductivity and power supplied.
