---------------------------------------------------------------------***--------------------------------------------------------------------The coagulation process involves the addition of a coagulant to the water, which destabilizes the producing significant amounts of wastewater, which suspended particles and forms larger aggregates called can be highly contaminated with dyes, chemicals, and flocs. These flocs can then be their effectiveness in other pollutants which affects the land and soil that coagulation. However, the use of these chemical leads to land pollution and soil degradation.In coagulants can raise concerns about the potential health response to the environmental impact of this and environmental impacts of residual chemicals in the wastewater, there is a growing need for sustainable treated water. In contrast, natural coagulants offer an and cost-effective treatment methods. Coagulation is environmentally friendly alternative. Natural one of the effective method usually chemical coagulants, derived from plant materials, have been coagulants are widely used but in our natural found to be effective in the coagulation process. cogulants are used for the purification of textile Examples of natural coagulants include chitosan, wastewater. The main aim of this experiment is to Moringa oleifera seeds, and tannins from various plants. reduce the environmental impact by purifying the Moringa oleifera seeds, for instance, contain cationic textile waste water using natural coagulants i.e proteins that can bind to negatively charged particles in moringa seeds, casava powder and alum (chemical water, allowing them to clump together and be easily coagulant for more effectiveness and compared to separated. Chitosan, derived from the shells of other chemical coagulants alum produce low sludge) crustaceans, has also been shown to be effective as a and using the purified water for other various natural coagulant due to its positively charged nature. purposes such as gardening,washing and other Using natural coagulants is beneficial as they are domestic purposes .In this starategy after generally biodegradable, pose fewer health risks, and coagulation the water is carried out to the step have minimal environmental impact compared to filtration and as a final step neem and lemon peel as traditional chemical coagulants. Additionally, natural disinfectants. The experiment was carried out by coagulants can be easily sourced, making them an changing the pH, turbidity, total solids, dissolved attractive option for water treatment in resourceoxygen, hardness according to the permissible limited settings. It is important to note that the parameters. The removal efficiency of turbidity after effectiveness of natural coagulants can vary depending coagulation is 70% and after filtration turbidity on water quality and the specific application. Research removed upto 90%, and after disinfection the and testing are necessary to determine the most removal efficiency of Turbidity, Colour, Odour, pH, suitable natural coagulant for a particular water Total hardness, Total Solids, and Dissolved solids are treatment scenario. Overall, the use of natural 99.7%, 95%, 99.6%, 92.6%, 90.5%, and 99.512%. coagulants presents a promising sustainable approach to water treatment, providing a safer and more Keywords— Textile wastewater, natural coagulants, environmentally friendly option for coagulation in Moringa seeds, Cassava, Neem leaves, Lemon peel. water treatment processes. This project aims to explore 1.INTRODUCTION the effectiveness of natural coagulants in removing pollutants from textile waste water, thereby reducing its The textile industry is known for producing significant environmental impact. Through this research, we hope amounts of wastewater, which can be highly to contribute to the development of sustainable contaminated with dyes, chemicals, and other methods for treating textile waste water, ultimately pollutants. In response to the environmental impact of leading to a cleaner and healthier environment. this wastewater, there is a growing need for sustainable and cost-effective treatment methods. One potential solution is the use of natural coagulants for the purification of textile waste water. This process is crucial for the production of clean and safe drinking water and for the treatment of industrial wastewater.
