Innovative Technologies for the Treatment of Industrial Wastewater

This book highlights advances in sustainable wastewater treatment technologies, particularly biological wastewater treatment, cavitation-based treatment, hybrid water treatment, membrane technologies, advance oxidation processes, and adsorption. The book focuses on a variety of advanced treatment techniques that are useful for the degradation of organic components, dyes, heavy metals effluent, etc. in wastewater.

Industrial wastewater consists of variety of discharges based on the type of industry, such as the dairy/food industries, which generate more fats and high BOD value with variation in the pH value, while the electroplating industry may expel more inorganic matter and dissolved solids. The oil extraction industries will have more solvents contained in the effluent, and dyes and textiles industry create a higher organic load with high TDS. Hence, every type of manufacturing industry needs a different method for the treatment of its effluents.

Looking at the use of intensified chemical processes in order to make cleaner environment, Innovative Technologies for the Treatment of Industrial Wastewater explores the new and innovative methods for pollutant removal that will prove useful for a variety of industries.

Conventional wastewater treatment processes requires more energy and involve expensive equipment, which involves capital and maintenance costs. Sustainable wastewater treatment technologies, however, involve less generation of energy and employ more economically feasible treatment methods, as well as less equipment and maintenance cost, and less energy usage and equipment cost.

This book will be a valuable reference for all types engineers who are working in industry/academics who are looking for innovative and sustainable methods to deal with harmful wastewater effluent.
