The treatment of a fertilizer company's effluent was evaluated using lime and electrodialysis reversal (EDR) for phosphate removal, water and chemical recovery, and effluent Phosphate could be reduced from 3 800 to less volume reduction. than 50 mg/l at pH 8.5 with lime: however, phosphate removal f
