Highly Efficient and Selective Electrodialysis Membranes for Advanced Wastewater Purification

Wastewater purification is an essential part of environmental management, and it requires technologies that are more energy-efficient and effective at cleaning water, especially for meeting sustainable development goals (SDGs). This chapter examines new advancements and provides an extensive summary of electrodialysis (ED) membrane technologies that offer improved efficiency and selectivity. Several studies have reported that integrating cutting-edge materials like ion-selective coatings and modified polymers in ion transport membranes enhances overall membrane efficiency and selectivity. System optimization strategies, such as better membrane design and setup, are also investigated to lower energy usage and operating expenses. This chapter critically evaluates the state of the art, highlighting significant developments and their effects on the wastewater treatment industry. This chapter summarizes key results about new materials and design approaches to improve ED efficiency in treating wastewater. The ultimate objective here is to aid in creating long-term remedies for the urgent problems caused by water shortage and pollution.
