Abstract
Industrialization plays an important role in the growth of a nation. But it is also added to the deteriorating condition of our ecosystem. Pollution, be it aquatic, terrestrial, or airborne, has affected our environment drastically and the surge of industries and growing population plays a major role in it. Innumerable basic and advanced techniques degrade the contaminants in wastewater. Most of these techniques are efficient but have several drawbacks too. The biological technique is one such viable approach in which there are no eminent downsides. This article presents a brief investigation of the biological treatment of wastewater, namely biofilm technology. Recently biofilm treatment technology has garnered a lot of attention due to its efficiency, inexpensiveness, and ease of incorporation into various conventional treatment techniques. A succinct analysis is provided about the mechanism of biofilm formation and its application in various systems in fixed, suspended, or submerged conditions. Details of the application of biofilm technology in lab-scale and pilot-scale treatment of industrial effluents are also discussed. This study is crucial to understand the competency of biofilms and to utilize the idea for further development of the technology for better management of wastewater. Pollutants such as BOD, COD can be removed up to 98 % with the help of Biofilm reactor technologies, making it one of the most efficient systems for wastewater treatment.
期刊介绍:
The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere.
The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
