TREATMENT OF PAPER INDUSTRY WASTEWATER

A wastewater of paper industry was treated using two different hydrocyclones (48 mm, and 73 mm) followed by Electro-coagulation (EC) process as a second stage to enhance the treatment process. The effect of design and operating parameters on the separation efficiency was investigated. Separation efficiency of 77 % can be obtained for both hydrocyclones.  The treatment process has a great potential to reduce the COD, BOD, TS, TSS, color and turbidity.
