Among the various emerging contaminants, pharmaceuticals (PhACs) seem to have adverse effects on the quality of water. Even the smallest concentration of PhACs in ground water and drinking water is harmful to humans and aquatic species. Among all the deaths reported due to COVID-19, the mortality rate was higher for those patients who consumed antibiotics. Consequently, PhAC in water is a serious concern and their removal needs immediate attention. This study has focused on the PhACs' degradation by collaborating photocatalysis with membrane filtration. TiO-based photocatalytic membrane is an innovative strategy which demonstrates mineralization of PhACs as a safer option. To highlight the same, an emphasis on the preparation and reinforcing properties of TiO-based nanomembranes has been elaborated in this review. Further, mineralization of antibiotics or cytostatic compounds and their degradation mechanisms is also highlighted using TiO assisted membrane photocatalysis. Experimental reactor configurations have been discussed for commercial implementation of photoreactors for PhAC degradation anchored photocatalytic nanomembranes. Challenges and future perspectives are emphasized in order to design a nanomembrane based prototype in future for wastewater management.
在各种新兴污染物中，药品（PhACs）似乎对水质有不良影响。即使是地下水和饮用水中最小浓度的 PhACs 对人类和水生生物也是有害的。在所有因 COVID-19 报告的死亡病例中，那些使用抗生素的患者的死亡率更高。因此，水中的 PhAC 是一个严重的问题，需要立即关注它们的去除。本研究通过光催化与膜过滤协同作用来研究 PhACs 的降解。基于 TiO 的光催化膜是一种创新策略，证明了 PhACs 的矿化是一种更安全的选择。为了突出这一点，本文详细阐述了基于 TiO 的纳米膜的制备和增强性能。此外，还利用 TiO 辅助膜光催化强调了抗生素或细胞抑制剂的矿化及其降解机制。讨论了用于固定化光催化纳米膜的 PhAC 降解光反应器的实验反应器配置，以实现商业化。强调了挑战和未来展望，以便为未来的废水管理设计基于纳米膜的原型。
