Degradation of emerging pollutants

Manganese-oxide materials have been reported as efficient oxidants for the degradation of endocrine disruptive chemicals such as estrone, 17jS-estradiol, bisphenol A and bisphenol F, among others. Xu et al. studied the oxidative removal of several endocrine disruptors from water using synthetic 5-Mn02 (surface area = 128 m g ) as well as the factors that influenced its 

Supported manganese-oxide catalysts were prepared in three alumina-based supports mesoporous synthetic and commercial 7-AI2O3 (surface areas of 287 and 184 m g , respectively) and nonporous a-Al203 (surface area = 35 m The hybrid materials were tested in the catalytic ozo-

Fungal-Mediated Degradation of Emerging Pollutants in Sewage Sludge... 

Before achieving the development of an industrial scale process, the research must follow different stages. First of all, the researchers have as an objective to demonstrate that the WRF are capable of degrading different families of emerging pollutants. Most of the studies have been carried out in liquid media, and a review is presented in Chaps. 6, 7, and 8. 

The use of membrane reactors for enzyme-catalyzed bioremediation processes is potentially beneficial in terms of improving the process economics by enabling enzyme reuse and enhancing overall efficiency and robustness. On one hand, various enzymes can efficiently degrade wide varieties of emerging pollutants. On the other hand, membrane reactors can eliminate...
