EFFECT OF 2D ELECTROCOAGULATION ON PHOSPHATE REMOVAL FROM UASBR TREATED SEWAGE

Previous study showed that NaCl when employed in EC for UASBR sewage electrocoagulation shows insignificant effect on COD and turbidity removal. Further UASBR has limitation of un altered nutrient level in effluent hence this study was undertaken to analyze effect of NaCl addition on EC with respect to phosphate removal. Response surface methodology showed here significant effect of NaCl on phosphate removal which is quite different finding when compared to previous study. Hence thorough investigation for significance of process variables on focused parameter is always necessary in EC process'
