Abstract

Industrial wastewater is a complex mixture of organic and inorganic substances, including nutrients, heavy metals, salts, and ionic components. Efficient removal of these compounds, along with achieving Zero Liquid Discharge is one of the biggest concerns faced by manufacturing industries. With the advancement in production and casting processes, followed by membrane modification, membrane-based hybrid technology has started gaining popularity since the early 2000s. Membrane-based treatment technology or membrane bioreactors (MBRs), coupled with other treatment processes, such as advanced oxidation processes (AOPs), and reverse and forward-reverse osmosis (RO/FO) is adopted in industries as an alternative to conventional wastewater treatment due to their ease of operation, and superior performance. This review chapter highlights the underlying mechanism and application of membrane-based hybrid processes, such as AOP-MBR and RO/FO-MBR, chemically aided-MBR to treat industrial wastewater. Other hybrid-MBRs integration of MBRs with nanomaterials, and the role of several factors that influence MBR operation are also covered in this review.
