Potable water has become a valuable, and sometimes, scarce resource due to population growth and industrial activities. Therefore, technologies that can process and generate this product are necessaries to avoid a global scenario of water scarcity in the following years. Reverse osmosis desalination using membranes is one of the most used strategies to produce potable water. However, polymeric membranes are susceptible to fouling and chlorine attack, which reduce their lifespan. Different approaches have been used to solve these problems such as the incorporation of nanocharges on the polymeric matrix of the membranes. In this work, the incorporation of graphene oxide on the polyamide membranes using different insertion routes was reviewed. The main results show that using graphene oxide as an additive for the thin film composite membranes, highly improves their performance in desalination systems as shown with the increase in 80% of the permeate flux while retaining salt rejection, besides, the addition of this nanocharge potentially increased chlorine resistance in 25%.

由于人口增长和工业活动，饮用水已成为一种宝贵的，有时是稀缺的资源。因此，必须采用能够加工和生产该产品的技术，才能避免在接下来的几年中出现全球水资源短缺的情况。使用膜进行反渗透脱盐是生产饮用水的最常用策略之一。然而，聚合物膜易于结垢和氯气侵蚀，从而降低了它们的寿命。已经使用不同的方法来解决这些问题，例如在膜的聚合物基质上掺入纳米电荷。在这项工作中，审查了使用不同的插入途径将氧化石墨烯掺入聚酰胺膜中。主要结果表明，使用氧化石墨烯作为薄膜复合膜的添加剂，
