Algal and phycology-based approaches for wastewater treatment have recently gained interest. highlights advanced algal-based technologies developed or being considered for wastewater treatment along with the opportunities that existing technologies can provide at an industrial scale. It covers recent findings on algal-based approaches for the removal of heavy metals, organic pollutants, and other toxicities from sewage and industrial effluents and supplies in-depth analysis on technologies such as biosorption and bioaccumulations. Advanced mathematical modeling approaches to understand waste removal and resource recovery from wastewater are illustrated as well. The book: This book is of interest to researchers, graduate students and professionals in phycology, microbiology, bioremediation, environmental sciences, biotechnology, wastewater treatment, resource recovery, and circular economy.
