Membrane science and technology is increasingly playing an important role in maintaining environmental health. Polymer based membranes in particular show great potential in removing environmentally hazardous pollutants from the wastewater. Membrane technology has also been widely used for ground, surface and seawater desalination which is serving the humanity by providing high quality drinking water. Polymeric membranes have been categorized based on their pore size and their distribution which make them tailor made and innovative separation media namely, reverse osmosis, nanofiltration, ultrafiltration, microfiltration and forward osmosis. All these membrane process require high performing membranes as separation media. This chapter give detailed account of membrane preparation techniques, membrane modules and their applications in different fields. Further, the ideas covered in this chapter are fundamental to all membrane processes. Transport processes, membrane preparation, and flow separation effects are just few of the topics that have been studied.

This review provides insight into the application of membrane technology in the filtration of aqueous solution generated from different industries. Due to the ever-evolving and demanding strict attention to rules and regulation for discharging of oily waste water, researchers have investigated membrane technology as a best and suitable method for separation of oil in oil-water emulsion. Membrane-based separation processes are becoming a novel material to treat oily wastewater due its facile operation process and effective in removal of oil from oil/water emulsion. This review summarizes or highlights the recent development of advanced membrane technology employed to separate oil in water emulsion using polymer and ceramic-based membranes and modified membranes via blending, coating, grafting and other techniques. Moreover, integrated membranes system to achieve high separation efficiency over single membrane process is also discussed. Perspective and conclusions concerning the future development of filtration membranes for treatment of oil in water mixture are also provided. A review of membrane technology for oil/water emulsion treatment could have a substantial contribution in developing novel membranes and modification of the existed membranes.

“…It has characterized by rapid reaction, mild conditions and easy control in degrading organic compounds (Wu et al, 2021). NCM has been widely used in the field of environmental science (Yang et al, 2018). For example, hydroxyl radicals can be generated on the NCM surface, thereby promoting the oxidation and degradation of organic pollutants (Fridley et al, 2013).…”

Nitrocellulose membranes (NCM) have broad application prospects in the field of organic wastewater treatment. In this research, acid orange 8 was used as the target pollutant, and the effects of factors, such as concentration, light intensity, anions, and cations, on the photodegradation of acid orange 8 were investigated under simulated sunlight by NCM. The results showed that the degradation rate constant of acid orange 8 in the NCM system was 1.94 × 10−3 min−1, which was 27.3 times that in the pure water. The photodegradation rate increases with decreasing concentration in the range of 20–120 μmol/L for acid orange 8. The photodegradation rate increased with increasing NCM area. The degradation effect of acid orange 8 increased with the increase of light intensity. Acidic conditions were favorable for the degradation of acid orange 8. The optimal conditions for photodegradation of acid orange 8 were the solution concentration of 20 μmol/L, membrane area of 17.35 cm2, light intensity of 481 μmol/(m2s), and pH value of 3.0. The effect of different components in water on the photodegradation of acid orange 8 was different. Ca2+, Mg2+, and NO3− could promote the photodegradation of acid orange 8, while CO32- could inhibit the photodegradation. The effect of degrading acid orange 8 by NCM under light conditions is obvious, which can provide a new method for the removal of acid orange 8 in wastewater.
