Abstract

In this study, the potential of chitosan as a coagulant for the treatment of wastewater was investigated. The effectiveness of chitosan was evaluated by measuring the removal efficiency of various pollutants, including turbidity, TSS, TDS, COD, BOD5, nitrate, and phosphate. The experimental results showed that chitosan was effective in removing pollutants from wastewater, with the highest removal efficiency achieved at a dosage of 10g. The statistical analysis confirmed that there was a significant difference in the removal efficiency of chitosan at different dosages. This study tends to explore the use of bio-material such as chitosan as a sustainable and effective coagulant for wastewater treatment instead of the regular use of synthetic coagulants like alum and also highlights the need for further research to optimize the operating conditions and evaluate the economic feasibility of chitosan coagulation.
