Abstract

In this study, treatment of pulp and paper wastewater was investigated. Wastewater from pulp and paper industry was treated by coagulation-flocculation method using alum (Al2(SO4)3) and polyaluminium amide (PAM). The various chemical dosage were tested such as 1000 ppm, 2000 ppm, 3000 ppm, 4000 ppm, 5000 ppm, 6000 ppm and the maximum removal efficiency percent of Total Suspended Solid (TSS), Total Dissolved Solid (TDS), Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD) were found to be 69%, 28%, 62%, and 80%,  respectively. According to the results, the removal of turbidity to a maximum level of 98% at dosage of 5000 ppm. This technology can prove to be eco-friendly processes.
