Performance Evaluation of Water Filter Made from Oyong (Luffa сylindrica) Fiber Coated with Silver Nano Particles for Coliform Bacteria Removal in Wastewater

Abstract

Oyong fiber (OF) is widely available natural fiber, the material characteristics and porosity make it a suitable alternative for filtration media. Accordingly, to investigate the potential use of OF as filter material in the wastewater disinfection process, this study applied different silver nanoparticles coating onto OF and proposed a new filter structure at lower cost. The OF coated AgNPs and OF coated Ag-GO were successfully synthesized following the chemical reduction methods as reported in the literature. SEM image shown that silver nanoparticles were randomly distributed on the surface of OF. Both OF coated AgNPs and Ag-GO exhibited a good disinfection capability for Total Coliform removal from wastewater. The OF coated Ag-GO have better Total Coliform Log Removal Value (LRV) of 3.3 and still maintain stable disinfection ability even at high filtration rate.
