Assessment of Total Organic Carbon (Soluble and Suspended) Removal in a Bio-Ozone-Treatment of an Industrial Wastewater with and without Sediments

In this research, removal of soluble and suspended Total Organic Carbon (TOC) with and without sediment in treatment of an industrial wastewater system before and after ozonation was studied and compared. Wastewater of pulp factories which are by-products of cellulose causes a hazardous water vapor that is dangerous because of containing different combinations of chlorophenol and the most important purpose of this research was ozone usage in wastewater treatment system to remove such combinations as well as the total organic carbon. Since ozone is a highly oxidant agent, the pilots were made of materials resistant to ozone and the important parameters which should be considered well are ozonation time, and ozonation dose. After the treatment, the measured soluble and suspended TOC in the cyclic ozonation-biotreatment system compared to the soluble and suspended TOC in the treatment method without ozonation. Sedimentation was the other factor which was considered in this experiment and TOC was measured with and without sediments. The comparison revealed that the outstanding efficiency of the cyclic ozonation-biotreatment system in removing both soluble andd suspended TOC with and without sediments is extremely considerable.
