The dairy industry is generally considered to be largest source of food processi ng. These industrial wastewater is characterized by high COD, TDS, turbidity a nd nitrates. This wastewater is treated in two stages, oagulation and vermin biofiltration. Coagulation was used as a primary treatment in which jackfruit seed powder is used as a coag ulant in removing turbidity. Vermi biofiltration was used as secondary treatmen t of dairy wastewater in removing COD and nitrates using the Eisenia fetida earthworm species and wetland plant Cyprus rotundus. The earthworms’ gut acted as a bioreactor and they reduced the dairy wastewater solid and liquid organic wastes through ingestion and expelling these as vermicompost. 500 gm earth worms were used in the vermifilter. The treated water pH increased from being acidic to neutral. In dairy wastewater, chemical oxygen demand (COD), total dissolved solids (TDS) , turbidity and nitrates decreased by 85.3%, 99.8%, 99.5% and 93.6% respectively through vermifiltration. Vermifiltration significantly decreased the dairy water physicochemical parameters compare d to an ordinary bio-filter without earthworms.
