Evaluation of Dairy Industry Wastewater Treatment Efficiency Using Coconut Husk, Sugarcane Bagasse, and Limestone as Filter Media

The raw dairy wastewater collected from Dinshaw’s Dairy Foods Ltd., Five Star MIDC Industrial Area, Butibori, Nagpur exhibited significantly high organic and suspended pollutant concentrations due to intensive dairy processing, equipment washing, floor cleaning, packaging operations, and sanitation activities. Laboratory analysis was carried out at Nilawar Laboratories (NABL Accredited Laboratory – TC-9782) using standard IS 3025 analytical methods. The obtained wastewater characteristics confirmed the high-strength nature of dairy effluent requiring effective treatment prior to discharge or reuse.
