Abstract: Conventional wastewater treatment processes are expensive and require complex operations and maintenance. They also generate large volumes of secondary waste that must be appropriately disposed. This book discusses management options, assessment and environmental issues of industrial waste. Chapter One focuses on a new method to treat wastewater containing acrylic acid in petrochemical industries. Chapter Two covers topics on nutrient cycling in wastewater treatment plants, the characteristics of industrial pollution, the industrially consolidated processes for wastewater treatment, the concept of process intensification applied to wastewater treatment, the emerging processes to wastewater treatment and the concept of biorefinery applied to wastewater treatment, summarizing a range of useful techno-economic opportunities to be applied on wastewater treatments plants. Chapter Three studies the residual material in order to determine its suitability for reuse as fine aggregate in clay mixtures. Chapter Four explores the feasible utilization of orange peels arising from juice production as biosorbent for removal of water pollutants.
