Advances in engineered design and performance of photocatalytic membrane reactor for polluted water treatment

Department of Civil Engineering, Indian Institute of Technology Hyderabad, Hyderabad-502 285, Telangana, India E-mail: ambika@ce.iith.ac.in Manuscript received online 06 December 2020, accepted 26 December 2020 The availability of clean water is a global concern. Photocatalysis is seen to be one of the advanced water treatment technique and coupling it with the membrane will give an upper edge over other methods. This paper presents an in-depth detailing of the photocatalytic membrane reactor (PMR). Different methods of preparation of photocatalytic membranes such as chemical vapor deposition (CVD), layer-by-layer (LbL), spraying, and phase inversion are described with a variety of a photocatalyst. Various factors influencing the performance PMRs and reviews the advances in the design and operational parameters of PMRs are comprehensively described and discussed. The PMRs with both immobilized and suspended photocatalyst are discussed and presented in this review article
