摘要

Wastewater treatment technologies are now being progressively utilized as establishments capable of facilitating the recovery of vital resources such as water, nutrients, and energy for advantageous use and reuse. The membrane technology, a well-established municipal and industrial wastewater treatment method, has gained significant recognition worldwide. However, there are still hurdles to overcome, such as higher energy consumption and fouling of membranes. Recent progress in developing hybrid configurations for advanced membrane technology has been studied to address these challenges. This paper explores the advancements in hybrid membrane reactors and processes, including arrangements as well as combinations with other technologies. Specifically, the membrane bioreactor has effectively integrated with advanced oxidation and/or separation approaches to treat municipal and industrial wastewater. Furthermore, the hybrid photocatalytic-membrane process has introduced permeability, hydrophilicity, rejection, antifouling, and photodegradation effectiveness, resulting in efficient wastewater removal techniques. Integrating electrochemical processes with membrane bioreactors has also drawn attention, particularly for parallel improvement in removal efficiencies, and helps mitigate foulant deposition into the membrane. Advanced oxidation processes have become an essential component of industrial wastewater treatment, particularly for contaminants of greater concern. The paper further discusses feasible combinations of advanced oxidation methods and possible future development paths for hybrid membrane systems.
