Wastewater Treatment Using Natural Coagulants

Research Paper (postgraduate) from the year 2024 in the subject Engineering - Chemical Engineering, grade: A, course: Chemical Technology, language: English, abstract: Water contamination is worsening globally due to industrialization and population growth. The pharmaceutical industry significantly contributes to this issue by releasing wastewater containing harmful pollutants. To mitigate this, advanced wastewater treatment technologies are essential. Coagulation is an effective method for treating wastewater, involving the use of natural or chemical coagulants to remove contaminants. However, chemical coagulants pose environmental and health risks due to residual toxicity and sludge disposal issues. As a sustainable alternative, natural coagulants like moringa seed powder, banana peel powder, and soya chunk powder were examined for their effectiveness in treating pharmaceutical wastewater. These coagulants possess dimeric properties that help neutralize and absorb colloidal charges, facilitating pollutant removal.
