Abstract

Disinfection using ultraviolet (UV) light for drinking water can eliminate pathogenic bacteria in water. The use of UV light in disinfecting water has existed from 1906 until now. UV treatment is very efficient and effective in killing microorganisms in water based on the results of previous studies. In the academic field, there have been many studies related to the use of UV light as a disinfectant for drinking water. The study used different methods and applications of research. So we need a literature review to provide a review related to the use of ultraviolet light technology as a disinfection in drinking water. Literature study through a systematic approach to analyzing data in a simple manner that aims to collect and summarize research data that has been done before. The journals used in this study were obtained through journals that have been registered with ISSN, Science Direct, JSTOR, Scopus, Google Scholar, Nature, and DOAJ, which have been published for the past 10 years regarding the use of UV rays in disinfecting drinking water. The use of ultraviolet (UV) light can disinfect drinking water. However, 31% of the literature study results, disinfection of drinking water with UV is still above the threshold. Effective wavelengths to deactivate microorganisms in the range of 250 to 270 nm. UV rays can damage the DNA/RNA of microorganisms in water. The time of disinfection using UV depends on the method of applying the UV lamp used. The effectiveness of UV can be influenced by turbidity and total suspended solids (TSS) in water. Disinfection with UV light for drinking water must quality for the quality standards that are odorless, tasteless, colorless, TDS 500 mg/l, and have a turbidity level of 5 NTU by following per under the Minister of Health Regulation regarding drinking water requirements.
