| Abstract | ||
| In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and germs. Today nanoparticle, nanomembrane and nanopowder are used for detection and removal of chemical and biological substances includes metals, nutrients, organics, viruses, bacteria, parasites antibiotics. Nonmaterial's reveal good result than other techniques used in water treatment because of its high surface area (surface/volume ratio). The aim of this work is to study effect of silver nanoparticle Ag NPs before and after photofragmentation as coagulant and as disinfectant in wastewater; this has been carried out through flocculation, coagulation, and disinfection techniques. Flocculation has been carried out using silver nanoparticle. Effect of each of the previous techniques on PH, total dissolved solids, total suspended solids , biological oxygen demand, chemical oxygen demand ,total coliform and fecal coliform were studied considered The optimum practical conditions for each technique and for the whole study have been selected. | ||
