Volume 2 addresses the various biorefinery aspects and applications of algal-based wastewater treatment in industrial and domestic contexts. The analyses are approached from multiple perspectives, including biotechnology, commercial, economic, and sustainability. The authors discuss the potential of microalgae for integrated biomass production utilizing various resources to treat wastewaters, and include evaluations of the economical and commercialization potential for such processes.

This book brings together environmental scientists and engineers to discuss the development of new approaches and methodologies which utilize microalgae for biological wastewater treatment. The researchers report their recent findings on microalgal removal of nutrients, heavy metals and other organic pollutants from sewage and industrial effluents. The technologies discussed here include biosorption and bioaccumulation of heavy metals, cell immobilization of algae, and mathematical modelling of metal uptake by cells. This book is unique in that it takes a practical approach to the subject matter and is a useful reference both in and outside of the laboratory.

Volume 1 focuses on the different aspects of domestic and industrial wastewater treatment by microalgae. The case studies include examples such as genetic technologies as well as the development and efficient use of designer consortia for enhanced utilization of microalgae. This volume provides thorough and comprehensive information on removal of persistent and highly toxic contaminants such as heavy metals, organic pesticides, polyaromatic hydrocarbons, endocrine disruptors, pharmaceutical compounds, and dyes from wastewater by microalgae, diatoms, and blue-green algae. Design considerations for algal ponds and efficient use of photobioreactors and HRAPs for wastewater treatment are some other highlights. This volume addresses the applications, potentials, and future opportunities for these various considerations in water pollution mitigation using algal technologies.

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. Comprehensively covers methods of wastewater treatment by algal cultivation and algal utilization Integrates the applications of algal cultures across wastewater treatment, nutrient recycling, CO2 sequestration, bio-energy and bio-based product generation Provides several international case studies to showcase actual algae-based pilot projects and facilities
