Investigation of Cephalexin Removal Using Biochar Derived from Nephelium lappaceum Seeds
Water and Wastewater Treatment
The improper disposal of drugs into bodies of water has become a severe environmental and health issue. Biochar synthesized from different agro residues could be a potential material for the adsorption of pollutants in aqueous environments. Nephelium lappaceum seeds were pyrolyzed at 600 °C in a...

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