ABSTRACT
Today the world is facing a major problem of getting rid of wastewater safely so that it does not disrupt the environment. The existing infrastructure and management systems are not adequate to cater to the increasing volume and changing quality of pollutants. Therefore, it becomes essential to manage wastewater and to use appropriate technologies and techniques for its treatment. In this study, the global research trends through wastewater treatment technologies was analyzed from 2000 to 2019 using Scopus database. Analysis of the existing database has been carried out based on the parameters such as trends in publication numbers, sources, institutions, authors, and countries. Scopus revealed a total of 11,757 journal articles, 2,933 conference proceedings, 1872 review papers, and 29,176 patents during this period, as on 9th May 2020, with the key words’ wastewater, treatment, and technologies. As per the analysis, China and USA portrayed maximum publications related to wastewater treatment technology.
