Advancement in membrane spacer technology: emerging trend and modification of three-dimensional printed membrane spacers for fouling mitigation
Aside from being essential for human needs, water resources are also in demand by various industries to ensure the sustainability of economic development in countries. However, the supply of clean and affordable water is slowly depleting to the point where it becomes a major issue that requires significant attention. The membrane filtration system is an effective method for purifying water, with a high potential to provide clean water with minimal energy. The membrane spacer is a significant component in the membrane filtration system that considerably influences its performance. The dominant challenge in membrane spacers is fouling, mainly biofouling, which leads to unwanted consequences that drastically decrease the system’s performance. This review focuses on the advancements in membrane spacer technology through the modification of geometric design, selection of materials, and evaluation of their impact on fluid dynamics and biofouling. Additionally, the review provides insight into the utilization of three-dimensional printing methods and three-dimensional simulations in advancing membrane spacer technology.
