Prospects of Synthesized Magnetic TiO2-Based Membranes for Wastewater Treatment: A Review

Abstract

Global accessibility to clean water has stressed the need to develop advanced technologies for the removal of toxic organic and inorganic pollutants and pathogens from wastewater to meet stringent discharge water quality limits. Conventionally, the high separation efficiencies, relative low costs, small footprint, and ease of operation associated with integrated photocatalytic-membrane (IPM) technologies are gaining an all-inclusive attention. Conversely, photocatalysis and membrane technologies face some degree of setbacks, which limit their worldwide application in wastewater settings for the treatment of emerging contaminants. Therefore, this review elucidated titanium dioxide (TiO2), based on its unique properties (low cost, non-toxicity, biocompatibility, and high chemical stability), to have great potential in engineering photocatalytic-based membranes for reclamation of wastewater for re-use. The environmental pathway of TiO2 nanoparticles, membranes and configuration types, modification process, characteristics, and applications of IPMs in water settings are discussed. Future research and prospects of magnetized TiO2-based membrane technology is highlighted as a viable water purification technology to mitigate fouling in the membrane process and photocatalyst recoverability. In addition, exploring life cycle assessment research would also aid in utilizing the concept and pressing for large-scale application of this technology.

Sewage Treatment Using Nanoparticles

“…As an alternative, the problem can be resolved by doping Ag nanoparticles with other metallic nanoparticles or its composites with metal-oxide nanoparticles. This may also result in the simultaneous removal of inorganic and organic substances from water and wastewater [41].…”

Membrane Bioreactors for Produced Water Treatment: A Mini-Review

“…A fundamental proceeding in the protection of quality water involves investigating and developing efficient technologies for the treatment and conversion of these complex toxic compounds into harmless ones. A viable route to water sustainability and fresh water scarcity is the recycling and reuse of reclaimed wastewater for non-potable and potable use [ 18 , 19 ]. This environmentally and financially sustainable approach also involves the recovery of resources such as nitrogen, organic matter, phosphorus, heavy metals, and value addition of sludge through its beneficial usage as fertilizers, green energy, and biosolids [ 20 ].…”
