Systematic Review on Water Pollution and Wastewater Treatment in the Asian Textile Industry

Abstract

The textile industry is one of the world's most polluting, especially in Asia, where wastewater discharge contributes to water pollution. Therefore, various methods for treating textile wastewater exist. The objective of this review is to identify these different wastewater treatment methods and analyze which are the most effective and environmentally friendly in removing pollutants and minimizing water pollution. The PICO method and keywords were used to formulate the research question and search the Scopus database, yielding 1479 articles. The PRISMA method was then used to select 46 articles that met the inclusion criteria. The results include an evaluation of different authors and their publications, along with a graphical analysis generated by VOSviewer showing the most prominent keywords. This study also reveals that advanced methods for treating textile wastewater are promising, while some conventional methods are becoming obsolete; however, barriers to implementing these methods exist.
