The performance of potassium ferrate for COD removal in AL-SAMAWAH refinery wastewataer

Potassium ferrate (K2FeO4) by way of the green method has numerous prospects for wastewater conduct. In recent years, K2FeO4 is ahead of care as having abilities aimed toward the elimination of different sorts of pollutants in refinery wastewater (RRW) recovery. during this education, the treatability competence of Potassium ferrate remained on the inspiration of the elimination of chemical oxygen demand in real oily wastewater The five effects operating limits: K2FeO4 concentration (25–100 ppm), oxidation time (2–10 min), pH (4-10), mixing rate (100–300 rpm),(25-100) for oxidation and coagulation correspondingly and their communicating belongings on the elimination of the above-mentioned pollutants were deliberate by means of the Box-Behnken design (BBD) of response surface methodology (RSM). Statistical replicas were industrialized then rummage-sale to reinforce the operating circumstances. Removal percentage with a quantity more than 93.5% was got, from this Potassium ferrate oxidation is acceptable intended for refinery wastewater remediation with organic compounds.
