OPTIMIZATION OF BIOLOGICAL TREATMENT OF DAIRY EFFLUENT USING RESPONSE SURFACE METHODOLOGY

Abstract

The current and unexpected growth of the world's population warrants an increased production of high quality animal protein. With this increasing demand for dairy, there is growing pressure on natural resources, including freshwater and soil. Dairy industry generates strong wastewater characterized by high biological oxygen demand (BOD) and chemical oxygen demand (COD) due to their high organic content. With increasing social awareness about the environment, the dairy industry is forced to treat its effluent effectively and efficiently before disposal into the public drainage. Large amount of water used in dairy industry results in significant generation of effluent volume; hence the challenge of its disposal cannot be ignored. The present study was conducted to analyze the microbial properties of the effluent from Dairy Plant and biological treatment of dairy effluent using Kluyveromyces marxianus and optimization of various conditions using response surface methodology (RSM). It was observed that bacteria, yeast and fungal count was 3.9 × 106 cfu/ml, 5.3 × 105 cfu/ml and 4.5 × 104 cfu/ml respectively and also the RSM model was significant and four factors interact with each other positively. Comparison between actual and experimental value indicated there was conformation between predicted and experimental data.
