Phycoremediation Processes In Industrial Wastewater Treatment

Increasing population and industrialization are the key pollutant contributors in water bodies. The wastes generated by industries are highly hazardous for humans and the ecosystem and require a comprehensive and effective treatment before being discharged into water bodies. Over the years, many up gradations have been introduced in traditional water treatment methods which were expensive and ineffective especially for removal of toxic pollutants. Phycoremediation has been gaining attention due to its mutual benefit in wastewater treatment and for valuable algae biomass production. Wastewater, especially sewage and industrial effluents, is rich in pathogenic organisms, organic and inorganic compounds and heavy metals that adversely affect human and aquatic life. Microalgae use these inorganic compounds and heavy metals for their growth. In addition, they also reduce pathogenic organisms and release oxygen to be used by bacteria for decomposition of organic compounds in a secondary treatment. In this book, the potential of microalgae in wastewater treatment, their benefits, strategies, and challenges are discussed. The increasing need of finding innovative, low-cost, low-energy, sustainable and eco-friendly solutions for wastewater treatment makes the publication of a book on phycoremediation timely and appropriate. Features: (1) Deals with the most emerging aspects of algal research with special reference to phycoremediation. (2) Studies in depth diversity, mutations, genomics and metagenomics study (3) An eco-physiology, culturing, microalgae for food and feed, biofuel production, harvesting of microalgae, separation and purification of biochemicals.

An Integration of Phycoremediation Processes in Wastewater Treatment reviews the potential of microalgae to treat wastewater containing highly recalcitrant compounds whose degradation is not achieved by the conventional existing treatments. In addition, the book describes how the microalgae collected after wastewater treatment can be used for obtaining added-value products, hence closing the loop and contributing to a circular economy. Finally, the technoeconomical aspects of this green technology are addressed, along with the design and development of photobioreactors, genetic aspects, metagenomics and metabolomics. Deals with emerging aspects of algal research, with a special reference to phycoremediation Covers diversity, mutations, genomics, metagenomics, eco-physiology, culturing, microalgae for food and feed, biofuel production, harvesting of microalgae, separation and purification of biochemicals Describes the techno-economical assessment, microalgal biotechnology and algal-bacterial systems for wastewater treatment Presents complex issues associated with cutting-edge biotechnological tools and techniques like next-generation sequencing methods, metabolomics and bioreactor design and development

This book adopts a “show and tell” approach to guiding readers in the area of industrial wastewater treatment and the facilities associated with such treatment. It assumes the reader is familiar with wastewater treatment theory but may be unfamiliar with the reasons why certain unit processes or equipment are included in practice, how these work, and why they fail therein. Industrial wastewaters are extremely varied and this complicates their treatment and discussion. Numerous tables showing industrial wastewater characteristics and photographs of facilities are provided so that the reader can better appreciate industrial wastewater treatment and its “culture” in Asia, and gain a degree of familiarity with the subject unachievable if only text descriptions were used. The book aims to provide a link between theory and practice. It does not only cover typical textbook material but also includes much information that would usually be accessible only to persons who have handled wastewaters and treatment facilities personally. The numerous examples provided have been drawn from the author's own field experience over two decades in Asia.

In the past, industrial wastewater treatment primarily focused on the removal of BOD and suspended solids. In recent years, however, the focus has changed to aquatic toxicity, priority pollutants, and volatile organics. This required changes in how we design and operate biological treatment plants. Many existing plants must be retrofitted. New approaches to meet new requirements are discussed in detail. The authors, with a combined experience of sixty years, have presented case studies for a wide variety of industrial wastewaters including pulp and paper, food processing, chemical and pharmaceuticals, and textile wastewaters. Data interpretation and process design are developed through the use of seventeen examples. Procedures for the laboratory and pilot plant generation of process design data are presented. Emphasis is placed on meeting the many new regulations governing industrial wastewater discharges.
