Assessment of microbial water treatment by direct solar radiation disinfection approach

Abstract

ABSTRACT The solar sterilization treatment innovation method can be implemented within households to address water pollution, especially those contaminants caused by microorganisms that may lead to waterborne illnesses. During review, water sources in the local area were assessed for turbidity and microbial quality. It was found that river water had turbidity levels of less than 30 NTU (Nephelometric Turbidity Units) during the dry season and typically up to 50 NTU during the wet season. This review aimed to understand the impact of these findings on the local area and its technological context. This study researched the utilization of sun-based radiation to clean the microbial mass tracked down in untreated water. Temperature and length of the openness are the two normal factors that were distinguished. The first water with a microbial heap of 40–55 (CFU) was presented to solar radiation at a temperature of above 44.5 °C outcome 0 (CFU) at the openness season of 6 h. The size and kind of materials utilized for this process were PET bottles of 1.5 L capacity with a half-dark tone. The factual examination at a 95% certainty information stretch has a p-value of <0.0001.
