“…Advanced oxidation processes using O 3 , H 2 O 2 , and Fenton (Fe 2? /H 2 O 2 ) have been found to be highly efficient in removing PPCPs (Esplugas et al 2007;Ghatak 2014), which generate hydroxyl radical to breakdown PPCPs oxidatively. Photodegradation and photocatalytic degradation processes have also been found to be able to degrade many PPCPs rapidly, which involve direct photolysis and indirect photolysis (Kanakaraju et al 2014;Yang et al 2014).…”

Pharmaceuticals and personal care products (PPCPs) consist of a variety of compounds extensively used for the treatment of human and animal diseases and for health or cosmetic reasons. PPCPs are considered as emerging environmental contaminants due to their ubiquitous presence in the environment and high environmental risks. In wastewater treatment plants using conventional activated sludge processes, many PPCPs cannot be efficiently removed. Therefore, there is an increasing need for more effective and cost-efficiency ways of removing PPCPs while treating wastewater. Algae-based technologies have recently attracted growing attentions for their potential application in wastewater treatment and hazardous contaminant removal, which are advantages in reducing operation cost while generating valuable products and sequestrating greenhouse gases at the same time. This work reviews the up-to date researches to reveal potential toxic effects of PPCPs on algae and algae-bacteria consortia, identify mechanisms involved in PPCP removal, and assess the fate of PPCPs in algae-based treatment systems. Current researches suggest that algae and algae-bacteria consortia have great potentials in PPCP removal but more works are required before algae-based technologies can be implemented in large scales. Knowledge gaps are identified and further research focuses are proposed in this review.

“…They have been successfully applied to treat wastewater effluents with high pollutant concentration (macropollutants) as a pre-treatment to biological processes [3,4]. More recently, they have been applied as a tertiary treatment, following a biological process, to treat effluents with low pollutant concentrations (micropollutants) [5,6]. AOPs are based on the generation of highly oxidative species, among which the hydroxyl radical is especially important due to its high oxidation potential (E 0 = 2.8 V).…”

“…Ultraviolet (UV)-based AOPs for the degradation of pollutants in water have been widely studied, and several reviews have been recently published concerning their performance and effectiveness [3][4][5][6][7][8][9]. AOPs generate highly reactive radicals, such as hydroxyl radicals, which typically degrade organic pollutants in water rapidly and nonselectively [6,7].…”

In this study, a small bench‐scale plug‐flow reactor was designed and characterized to demonstrate the feasibility of using UV/LEDs as a UV source in flow‐through advanced oxidation processes. The plug‐flow reactor was characterized by investigating the effects of residence time, H2O2/methylene blue molar ratio, and initial methylene blue concentration on methylene blue decolorization in water. Methylene blue was selected as a witness dye, because it does not degrade with H2O2 or with UV alone, and it has reduced absorption in the visible spectrum when reacted with OH radicals. UV/LEDs have been employed successfully in AOPs for water treatment in research‐scale systems, as demonstrated in this study. However, they currently have low optical output, which limits their applicability for water treatment to small point‐of‐use systems. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 857–863, 2017
