A Bibliometric Analysis of Dairy Wastewater Treatment

Abstract

Dairy-based industries are one of the industries that consume more water for the production of large quantities of milk and milk products. The water is employed in cleaning, cooling systems, segregation, and packing units. Thus, the effluents discharged release water heavily characterized by different nutrients, COD, BOD, and organic and inorganic substances. Thus, wastewater discharge becomes a significant concern. Utilizing the proper technology and strategies for wastewater treatment as well as managing wastewater becomes crucial. Using the Scopus database, this present study examines global research trends in wastewater treatment technologies between 2000 and 2023. The currently available database has been examined using criteria such as trends in publication numbers, authors, sources and countries. Scopus revealed 1611 journal articles, 215 conference proceedings, 117 review papers, and 74 book chapters during this period, as of March 2023, with the keywords’ Dairy, wastewater and treatment. The analysis showed that the top papers on dairy wastewater treatment technologies were from India and the United States.
