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

Adequate wastewater treatment in low to medium income cities worldwide has largely been a failure despite decades of funding. The still dominant end-of-pipe paradigm of treatment for surface water discharge, focusing principally on removal of organic matter, has not addressed the well-published problems of pathogen and nutrient release with continued contamination of surface waters. This book incorporates the new paradigm of integrated wastewater management for valorization without surface water discharge using waste stabilization pond systems and wastewater reservoirs. In this paradigm the purpose of treatment is to protect health by reducing pathogens to produce an effluent that is valorized for its fertilizer and water value for agriculture and aquaculture. Methane production as a sustainable energy source is also considered for those applications where it is appropriate. Emphasis is on sustainable engineering solutions for low to medium income cities worldwide. Chapters present the theory of design, followed by design procedures, example design problems, and case study examples with data, diagrams and photos of operating systems. Excel spreadsheets and the FAO program CLIMWAT/CROPWAT are included in examples throughout. Sections on engineering practice include technical training, operation and maintenance requirements, construction and sustainability. The book incorporates design and operating data and case studies from Africa, Australia, Latin America, Europe, New Zealand, and the US, including studies that have been published in French, Portuguese, and Spanish.

Valorization of Microalgal Biomass and Wastewater Treatment provides tools, techniques, data and case studies to demonstrate the use of algal biomass in the production of valuable products like biofuels, food and fertilizers, etc. Valorization has several advantages over conventional bioremediation processes as it helps reduce the costs of bioprocesses. Examples of several successfully commercialized technologies are provided throughout the book, giving insights into developing potential processes for valorization of different biomasses. Wastewater treatment by microalgae generates the biomass, which could be utilized for developing various other products, such as fertilizers and biofuels. This book will equip researchers and policymakers in the energy sector with the scientific methodology and metrics needed to develop strategies for a viable transition in the energy sector. It will be a key resource for students, researchers and practitioners seeking to deepen their knowledge on energy planning, wastewater treatment and current and future trends.

Tackling the issue of water and wastewater treatment nowadays requires novel approaches to ensure that sustainable development can be achieved. Water and wastewater treatment should not be seen only as an end-of-pipe solution but instead the approach should be more holistic and lead to a more sustainable process. This requires the integration of various methods/processes to obtain the most optimized design. Integrated and Hybrid Process Technology for Water and Wastewater Treatment discusses the state-of-the-art development in integrated and hybrid treatment processes and their applications to the treatment of a vast variety of water and wastewater sources. The approaches taken in this book are categorized as (i) resources recovery and consumption, (ii) optimal performance, (iii) physical and environmental footprints, (iv) zero liquid discharge concept and are (v) regulation-driven. Through these categories, readers will see how such an approach could benefit the water and wastewater industry. Each chapter discusses challenges and prospects of an integrated treatment process in achieving sustainable development. This book serves as a platform to provide ideas and to bridge the gap between laboratory-scale research and practical industry application. Includes comprehensive coverage on integrated and hybrid technology for water and wastewater treatment Takes a new approach in looking at how water and wastewater treatment contributes to sustainable development Provides future direction of research in sustainable water and wastewater treatment
