Using Ultraviolet Technique for Well Water Disinfection

Abstract

Ultraviolet rays are widely used to disinfect microbial water. Disinfection is a treatment process for drinking water. UV disinfection is one of the physical methods used to kill bacteria and destroy cells. In most cases, the physical process immediately purifies drinking water without the formation of toxic substances. Therefore, there are no bacteria in the water, so that it can be cleaned constantly. This research aims to obtain environmentally sustainable drinking water in conditions where clean water is scarce, such as water shortage. The pilot plant was established to evaluate a ceramic filter’s effectiveness in reducing turbidity, plankton, and anything else that could alter drinking water properties. As a result, some water purification stages, such as those used in water treatment plants, are reduced. To see how effective UV sterilization is in killing bacteria, especially fecal coliform and Escherichia coli bacteria. Work was done by taking samples from the well water from Al-Zaidan area in Abu Ghraib district. Before the sterilizer is inserted, this procedure works on water that meets specific requirements. Although it is a commercial filter, the ceramic filter is excellent at removing turbidity with removal efficiency (73∼89) %, the removal efficiency of dissolved solids (100) %, the removal efficiency of iron (75∼83) %, and the removal efficiency of bacteria (45∼53) %, which is an excellent removal efficiency. The UV sterilizer’s ability to remove bacteria has reached a removal efficiency of (100) %. This process is superior because it does not produce any secondary substances and has no effect on color, taste, or smell. Because water samples are taken from Groundwater, it contains high TDS content.
