- Abstract
The aim of this study was investigating the phosphate removal from aqueous environments by electrocoagulation (EC) in bipolar connection mode. In the study, iron plates were used as electrode with mucilage of Plantago ovata as a natural aid-coagulant and aid-flocculent. The several operational parameters such as the concentrations of phosphate, pH, operating time on the removal efficiency of phosphate were determined. The results showed that in the operating removal condition when mucilage was added as aid coagulant, the removal efficiency was improved. In this condition, the formed flocs in EC easily floated on surface of the solution. The process is completely effective in low concentration (100% removal in 5 mg/L phosphate). The sludge formed in EC with mucilage could be used to improve poor soils with low iron, phosphorus and organic matters.
