Abstract
Reuse of waste bio source from food industrial waste. In this study, concentrated dairy effluent was utilized to synthesis silver nano particles (AgNPs), which is used to prepare alginate composite micro beads were for slow delivery of silver. These beads were then used to disinfect dairy tertiary treated water. Initially, AgNPs were synthesized and characterized using Ultra Violet-visible spectrum (UV-Vis), X-Ray Diffraction (XRD) and High Resolution Transmission Electron Microscope (HRTEM). The composite beads were made from AgNPs and alginate. The physical structure and silver content were determined using optical microscope and Inductively Coupled Plasma Optical Emission Spectroscopy (ICPOES), respectively. Packed bed column study was carried to know the inactivation kinetics on reduction of total microbial load and coliform were carried out in tertiary treated water. This study confirms that these beads were effective in disinfecting water, which was mainly due to encapsulated and relatively slow release of AgNPs.
