This study explores the use of natural coagulants in the treatment of dairy wastewater, aiming to provide a sustainable, cost-effective alternative to traditional chemical treatments. Dairy wastewater, characterized by high levels of organic matter, nutrients, pathogens, and suspended solids, poses environmental challenges due to its impact on water quality. The experimental approach focused on testing various natural coagulants—watermelon seed, chickpea, moringa oleifera, tamarind seed, and neem powder—to assess their efficacy in reducing turbidity, a key pollutant in dairy effluents. The results indicate significant turbidity reduction across all natural coagulants, with neem powder achieving the highest efficiency at a relatively low dosage. Compared to conventional coagulants like ferric chloride and alum, the natural options demonstrated promising potential, reducing turbidity effectively while ensuring the treated water remains suitable for irrigation and other non-potable uses. This research highlights the viability of natural coagulants as environmentally friendly solutions for dairy wastewater treatment, contributing to sustainable water management practices.
