The Sustainable Development Goals (SDG) 2015, defined to achieve a better and more sustainable future, contains goal number 6 related to safe and affordable drinking water facility for all till 2030. The rural and remote areas in the developing countries predominantly face the scarcity of pathogen free drinking water leading to water borne diseases and deaths due to consumption of contaminated water indicating a need of advancement in the drinking water disinfection techniques. The paper discusses scientometric analysis of publication trends in chlorination as a popular disinfection techniques and research related to the Disinfection By Products (DBPs) that are produced due to the reaction between the disinfectant and naturally occurring organic matter in water.
The analysis of the existing SCOPUS database from year 2000 to 2020, indicates total of 1279 journal articles, 138 conference proceedings, 88 review papers, and 57 other documents, with the key words ‘drinking water, disinfection, and chlorination’. As per the analysis, United States and China presented maximum publications related to drinking water disinfection using chlorination treatment. The analysis of literature also indicates that there is huge amount of literature related to the formation of alternative DBPs and their hazardous effects on human health. However, as per scopus database only three research documents are registered till date for the removal techniques of DBPs produced after the disinfection process, indicating a need of further research in this area. The literature also suggests the need to engender new technology or optimize the existing technology for minimizing the formation of DBPs.
