Optimization of phenol degradation in a combined photochemical–biological wastewater treatment system

Slaughterhouse wastewater characteristics, treatment, and management in the meat processing industry: A review on trends and advances

“…Furthermore, AOPs may inactivate microorganisms without adding additional chemicals to the SWW in comparison to other techniques such as chlorination that are commonly used in water disinfection, thus, avoiding the possible formation of hazardous by-products (De Sena et al, 2009;Bustillo-Lecompte et al, 2015). Therefore, AOPs have come handy to be recognized as advanced degradation, water reuse, and pollution control processes showing excellent overall results as complimentary treatment (Tabrizi and Mehrvar, 2004;Mehrvar and Venhuis, 2005;Venhuis and Mehrvar, 2005;Mehrvar and Tabrizi, 2006;Edalatmanesh et al, 2008;De Sena et al, 2009;Cao and Mehrvar, 2011;Barrera et al, 2012;Mohajerani et al, 2012;Bustillo-Lecompte et al, 2013, 2014Hamad et al, 2014;Mowla et al, 2014;Ghafoori et al, 2015).…”

“…The UV/H 2 O 2 process has been found to be effective for SWW treatment. Oxidation and degradation of pollutants by UV/H 2 O 2 rely on hydroxyl radicals ( OH), a highly reactive species produced from the reaction of the H 2 O 2 with the UV light (Tabrizi and Mehrvar, 2004;Mehrvar and Tabrizi, 2006;Edalatmanesh et al, 2008;De Sena et al, 2009;Luiz et al, 2009;Cao and Mehrvar, 2011;Barrera et al, 2012;Mohajerani et al, 2012;Hamad et al, 2014;Mowla et al, 2014;Bustillo-Lecompte et al, 2015;Ghafoori et al, 2015). A schematic diagram of a single lamp UV/H 2 O 2 photoreactor system is presented in Fig.…”

Transient Behavior in Biodegradation of 2, 4 Dichlorophenol: Is It a Starvation Effect?

“…Phenolic compounds are among the most prevalent forms of chemical pollutants in the industrial wastewater, generated mainly from oil refineries, coal conversion plants, petrochemicals, polymeric resins, pharmaceuticals, smelting, and related metallurgical operations [5]- [7]. Phenols are well known for their high toxicity for human life, aquatic life and others [8]- [10].…”

Biodegradation kinetics of 1,4-benzoquinone in batch and continuous systems

“…The high amounts of chemical oxidants required to completely mineralize the organic contaminants make the chemical treatment processes uneconomical (Zazo et al 2005). Integrating chemical and biological treatments is an attractive alternative to minimize treatment costs for the removal of high concentrations of toxic compounds from wastewater (Edalatmanesh et al 2008).…”
