Water treatment is crucial for safe drinking water, especially in resource-limited regions. Natural
coagulants like Moringa oleifera, Nirmali Seeds, and Azadirachta Indica are sustainable
alternatives to chemical coagulants. They remove contaminants from water, promising potential
for rural and developing areas. However, further research is needed to optimize their application
and scale up for widespread adoption. Natural coagulants are environmentally friendly and costeffective,
making them a promising future solution. Water treatment is critical in ensuring access
to clean and safe water for various purposes. This paper explores the applications of natural and
chemical coagulants in water treatment. Natural coagulants, derived from organic sources such as
plants and seeds, offer environmentally friendly alternatives to conventional chemical coagulants.
Chemical coagulants, on the other hand, provide rapid and effective removal of impurities through
processes like charge neutralization and flocculation. The comparative effectiveness, costefficiency,
and environmental impact of both types of coagulants are examined, highlighting their
respective advantages and limitations. Additionally, emerging trends and innovations in coagulant
technology are discussed, offering insights into the future of water treatment practices.
