“…Advanced Oxidation Process (AOP) is an alternative technology that has been applied for the remediation of wastewater containing dyes [13][14][15], and other organic pollutants [16][17][18], showing good performance in terms of discoloration and degradation. The electro-Fenton (E-Fenton) process stands out among the various types of AOP, as one of the most efficient technologies for the oxidation of wastewater contaminated by dyes [19][20][21].…”

“…Since several EDCs are designed to be chemically and biologically stable over a wide range of environmental conditions, wastewater treatment plant (WWTP) often proves ineffective causing accumulation phenomena, even into drinking waters (Chong et al, 2012;Mompelat et al, 2009;Snyder et al, 2003). Novel environmentally-sustainable biological processes are an attractive option to the costly and energy-consuming chemical and physical approaches, which often cause undesired by-product formation (Husain and Qayyum, 2012;Ikehata et al, 2006).…”

a b s t r a c tThis study describes a multidisciplinary approach that investigates the breakdown potential of a laccase mediated system from Trametes pubescens MUT 2400 against several micropollutants including already recognized endocrine disrupting chemicals at their natural residual concentrations (from mg/L up to ng/ L).In model solution, the chemical speciation focused on a mixture of 18 analytes and adopted stir bar sorptive extraction with directed in-situ derivatization followed by gas chromatography and mass spectroscopy analysis. The method's key performance parameters were evaluated in consideration of the chemical peculiarities and complexity of real wastewaters: precision, accuracy, estimated working range extended to a wide residual concentration interval (10 ng/L to100 mg/L) indicated its fitness for purpose. Laccases were extremely active towards all the target compounds, both in term of removal yields and rate. The maximal percentage of removal was obtained for 4-t-butylphenol, 2-hydroxybiphenyl, 4-noctylphenol, salicylic acid and estrone (percentage of removal above 90%). Enzymes concentration played a central role and in most of the cases, the catalyzed reactions were very fast: the initial concentration of 9 compounds was halved within the first 3 h.The laccase-mediated treatment was then applied to a municipal wastewater collected in a real wastewater treatment plant, containing at least 9 xenobiotics as drugs, pesticides, plasticizers and personal care products. Although the harsh chemical and biological conditions of the effluent influenced enzyme stability, the reaction took place, and above 70% transformation was obtained for most analytes during the 24 h experiment. Bioassays were carried out to estimate the estrogenic activity (the E-screen test and the MELN gene-reporter luciferase assay) and the ecotoxicity (Lepidium sativum, Pseudokirchneriella subcapitata and Vibrio fischeri), demonstrating the capability of laccases to mediate an effective detoxification of the wastewater and a decrease of the estrogenic activity. treatment plant; U/L, enzymatic activity expressed as International Unit per liter; PR, percentage of removal; MEC, minimal effective concentration; t 1/2 , analyte half-life; Ti, Target Ions; RSD%, relative standard deviation percentage; LOQ, limit of quantification; QCx, quality control samples; Rel.Err %, relative error percentage; COD, chemical oxygen demand; GI%, germination index; I%, inhibition percentage of the algal growth or of the bacterial bioluminescence; EEQ, 17-b-estradiol equivalent quantity; RPE %, relative proliferative effect; TRANS%, rate of luciferase gene expression.

“…Due to the advances on water/wastewater treatment technologies, a variety of options is actually available to provide a high standard of wastewater treatment. These technologies include advanced oxidation technologies (AOTs), which have been widely investigated for the treatment of industrial wastewaters, particularly where the source waters contain high concentration of ambiguous, refractory and recalcitrant chemical compounds such as aromatics, pesticides, pharmaceuticals and personal care products, drugs and endocrine disruptors [9][10][11]. Despite their efficiency, the implementation of AOTs is not always economically affordable for local industries.…”

Abstract:Benzotriazole is used as corrosion inhibitor in many industrial sectors, such as the dairy industry. Due to its widespread use in various applications and everyday consumer products, this chemical easily reaches the aquatic environment, where it may have deleterious effects. In fact, benzotriazole has been included among the so-called emerging contaminants. In this work, the occurrence and fate of a benzotriazole based anticorrosive (BTA-A) during wastewater treatment in a dairy industry has been assessed. At this dairy, a new system for wastewater treatment based on the injection of pure oxygen was recently started. This system has been proved to be efficient, economic and able to stably operate under a wide range of chemical oxygen demand and total suspended solids inputs. Then, after detecting the presence of BTA-A in the effluent of the wastewater treatment plant, it was aimed to optimize oxygen injection for the removal of this anticorrosive together with the regulated parameters. The performance of the system was evaluated at a real scale during a month period, during which the mean removal performance of the oxygen injection based treatment was 91%, 90% and 99% for chemical oxygen demand, total suspended solids and BTA-A, respectively.
