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

by Anitha A. Dawn S. Muthukumaravel K. Praveen R.

Water and wastewater treatment and reuse

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...
