Membrane technology has been utilized for water purification application for a long time. Both polymeric and ceramic membranes have been center of interest for their tremendous contribution in this area. Despite their advantages, these synthetic membranes have limitations in terms of performance and durability. To meet the new demands and standards, mixed matrix membranes (MMM) have gained serious importance due to their ability to combine the features of the aforementioned membrane materials, offering better solutions in terms of performance, fouling, permeate quality and longevity. Besides such attractive features, MMMs have not yet reached sufficient maturity to challenge conventional membranes commercially. This review categorizes MMMs on its filler basis into four types; (i) inorganic filler-based MMMs, (ii) organic filler-based MMMs, (iii) biofillers-based MMMd, and (iv) hybrid filler-based MMMs. A discussion is extended to modules and cost of these membranes along with the specific applications of each type of fillers. It also identifies the issues and challenges in the MMM area and highlights the domains that remain to be investigated.

膜技术已被广泛用于水净化应用。聚合物膜和陶瓷膜都因其在该领域的巨大贡献而受到关注。尽管具有这些优点，但这些合成膜在性能和耐用性方面仍存在局限性。为了满足新的需求和标准，混合基质膜（MMM）由于能够结合上述膜材料的特性，从而在性能，结垢，渗透液质量和寿命方面提供了更好的解决方案，因此变得非常重要。除了这些吸引人的特征之外，MMM还没有达到足够的成熟度来商业上挑战常规膜。这篇综述根据其填充量将MMM分为四种类型；（i）无机填料基MMM，（ii）有机填料基MMM，（iii）基于生物填料的MMMd，以及（iv）基于混合填料的MMM。讨论扩展到这些膜的模块和成本，以及每种类型的填料的具体应用。它还确定了MMM领域中的问题和挑战，并强调了仍有待研究的领域。
