Abstract

The treatment of dairy wastewater using traditional wastewater treatment plants such as the
activated sludge is not feasible as it will require high energy rate to provide the required oxygen. This paper
presents experimental results of using Vermi Bio-filtration to treat wastewater from dairy industry. Samples of
wastewater were collected from Prasanthi Farms located in a small village of Kollam district, India. The sample
characteristics of pH, Total Dissolved Solids, Total Suspended Solids, Chemical Oxygen Demand, Oil &
Grease and Dissolved Oxygen were measured before and after vermi bio-filtration treatment. The
characteristics were measured at different time intervals of 12 hours (12, 24, 36, 48, and 60 hours). The
percentage changes of the above parameters after 60 hours are -18, 79, 75, 67, 69 and -31% respectively. the
method is inexpensive, it can capture all organic materials, capital and working expenses are low, there is no
foul scent, worm biomass would be used as nourishment for the cows, fish agro-business.
