Studies on Kinetics, Isothermal Modelling and Optimization of Cow Dung Adsorbent for Synthetic Dairy Wastewater Treatment

by AS A. SS D. KK M. Rajendran P.

Water and Wastewater Treatment

The dairy industry is a major food industry that processes raw milk into a variety of products. The milk processing factory produces DWE with soluble organic components, suspended particles, and trace elements. These components degrade, causing cloudiness and odour. Adsorbing total solids (TS) and...
