Characterization and Treatment of Dairy Wastewater

Abstract

Dairy wastewater is a strong organic and saline effluent whose characterization and treatment have not been sufficiently addressed. Dairy wastewater composition is highly variable due to raw milk used, the fraction of cheese whey and the amount of cleaning water used. Dairy wastewater generation in case study A is between 14800-15000 L/day. This research tries to conduct an exhaustive compilation of dairy wastewater characterization and a comparative study between the different features of dairy wastewater, COD, pH, chloride, TDS and TSS for dairy industry effluents. The treatments of dairy wastewater have also been by adsorption bed column analyzed. The advantages of adsorption bed column processes have been evaluated. The parameter of pre-treatment (i.e. flow rate, height of bed) in adsorption bed column systems are assessed. A removal efficiency of sawdust is 94.5% is obtained with 5% solids (5g solid/100g wastewater). Keywords: Dairy effluent characterization, Cheese whey wastewater, Adsorption bed column treatment.
