Popis: Present study was focused on purified terephthalic acid (PTA) industry wastewater treatment located at Port Qasim, Karachi. PTA wastewater containing high COD (100000 to 150000 mg/L) was treated with coagulate ferrous ion and then was oxidized independently with aqueous hydrogen peroxide using different doses at 45 °C for 1h. The resulting wastewater was passed through RO plant equipped with high porosity bio-ceramic membrane. It was observed that coagulation and oxidation processes have potential to reduce 87.9% COD but complete reduction up to 99.8% was achieved after passing the effluents from high RO plant equipped with high porosity ceramic membrane.
