Integrated Wastewater Management and Valorization using Algal Cultures provides a holistic view on coupled wastewater treatment and biomass production for energy and value-added products using algal cultures. Algal cultures provide low-cost nutrient (nitrogen and phosphorus) treatment and recovery from wastewaters, carbon-dioxide sequestration from waste gases, value-added generation in the form of bio-energy and bio-based chemicals, biosorption of heavy metals and biogas upgrading. The book addresses all these aspects in terms of role of algal cultures in environmental sustainability and circular economy. The production of high value products is addressed through pretreatment and anaerobic co-digestion of wastewater-derived microalgal biomass and microalgal biorefineries. The simultaneous dissolution and uptake of nutrients in microalgal treatment of anaerobic digestate is discussed, as is coupled electrocoagulation and algal cultivation for the treatment of anaerobic digestate and algal biomass production. Finally, optimization of algal biomass production is discussed using metagenomics and machine learning tools, and scale-up potential and the limitations of integrated wastewater-derived microalgal biorefineries is discussed.

Integrated Wastewater Management and Valorization using Algal Cultures offers an integrated resource on wastewater treatment, biomass production, bioenergy and value-added product generation for researchers in bioenergy and renewable energy, environmental science and wastewater treatment, as well as environmental and chemical engineering.
