Using bundle filters to process petrochemical secondary effluent for industrial reuse

The objective of this project is to study the advanced treatment technique for the secondary effluent from petrochemical wastewater treatment plants in order to meet requirements for the reuse of industrial wastewater. Based on the characteristics of the secondary effluent of petrochemical wastewater, a direct filtration process with highly effective filter is selected and designed. The test results indicate that the process can achieve good results in turbidity and COD removal. It can meet the need for the industrial reuse of the secondary effluent of petrochemical wastewater as the turbidity value of effluent is less than 3 and COD of effluent is less than 40 mg/l. A great economic efficiency is obtained. The filtration system costs low because of the longer operating cycle (14-24h). It is a creative achievement in the reuse of petrochemical wastewater, and is the pioneering study in China.
