This book reviews the status of developing tailor-made low-cost membranes and membrane-based separation processes for applications in wastewater treatment. It also presents an overview of industry-specific case studies upholding the waste-to-resource strategy for utilization of low-cost ceramic membranes in industrial wastewater treatment. This book highlights methods, results, and examples demonstrating that low-cost ceramic membranes possess similar features and advantages comparable to the commercially available ceramic membranes, thereby minimizing the prohibitive cost of their usage in wastewater treatment. Thus, the readers who are looking for more economical alternatives for wastewater treatment can be introduced with the cheaper membrane materials. It also discusses the selection and method of application of such membranes in the treatment processes. This book can serve as a valuable reference for researchers and professionals interested in wastewater treatment and allied fields.
