Abstract: Abstract In this research, a plant material (Strychnos potatorum seed powder) has been used as natural coagulants, and tested the ability to remove turbidity from synthetic water and industrial water samples. The results from industrial water samples were compared with synthetic water samples. Experiments have been conducted in the laboratory to assess the percentage (maximum) of turbidity removal at various levels (i.e., 50, 80, 110, 120, and 145 NTU) from collected and prepared samples. Parameters influencing the coagulation mechanism such as dosage and pH were reported most suitable parameters for maximum turbidity removal. In this regard, the percentage of turbidity removal varies between 46–78% and 50–84% for synthetic and industrial water samples, at an ideal pH level (6–7) respectively. In addition, the isotherm model (i.e., Langmuir and Freundlich) was used to assess the sorption analysis from experimental data sets, wherein the monolayer sorption of contaminants onto the seed powder of S. potatorum was detected. The outcomes highlighted the effect of sorption in the turbidity removal percentage from both synthetic and industrial water samples, advocating the use of S. potatorum as a cost-effective alternative for industrial wastewater treatment.
