Experimental Study of Organic Compound Removal from a Refinery Wastewater using Fly Ash Zeolite

In this work, an intensive study has been made on the removal efficiency of organic compounds from aqueous solution by sorption of zeolite (ZFA) prepared from raw fly ash (RFA). ZFA & RFA is characterized using XRD, SEM-EDX and FTIR. A real Siri petroleum refinery wastewater, containing a range of aromatic organic compounds, was treated using. Samples were collected from the inlet point of the biological treatment unit. Optimal suspended absorbent concentration, fluid pH, and temperature were obtained at amounts of near 100 mg·L−1, 3 and 45◦C, respectively. The identification analysis of the organic pollutants, provided by means of a GC/MS, equipped with headspace injection technique, showed that different petroleum compounds were degraded with high efficiencies.
