The specialized book "Treatment of Spentwash Using Microbial Fuel Cell Followed by RBC" provides a comprehensive analysis of the treatment of wastewater from spirits production. This wastewater, known as spentwash, poses a significant environmental burden due to its high organic loads and low pH levels. The authors, S. Anupama, N. V. Pradeep, and Uday S. Hampannavar, explore the anaerobic treatment of spentwash using microbial fuel cells, followed by aerobic post-treatment in a biological reactor system (RBC). The book is aimed at professionals and students in the fields of mathematics and natural sciences and offers valuable insights into innovative approaches to wastewater treatment that are both ecologically and economically sustainable.
