Emerging contaminants removal by full-scale ozonation Tertiary Treatment
2016Co-Authors: Y. Penru, Marina Coquery, C. Miege, A. Roussel Galle, L. Dherret, A. Guillon, M. Esperanza, B. Barillon, S. Martin Ruel, Jean-marc ChoubertAbstract:Dissemination of chemical substances in the environment is becoming a major issue and wastewater effluents are one the main point sources. The goal of the present work was to determine the performances on micropollutants removal of a recently developed process consisting in ozone contactor followed by a post-denitrification submerged biofilter. A full-scale Tertiary Treatment line (600 m3/h) built at Sophia-Antipolis wastewater Treatment plant (WWTP) was studied under various operating conditions (ozone and methanol dosage). The groups of micropollutants monitored include pharmaceuticals, hormones pesticides (domestic uses) and also compounds listed in the European Union Water Framework Directive such as metals, phthalates (DEHP) and alkylphenols. Preliminary results show that with an ozone dosage of 5 g/m3, the Tertiary Treatment line achieved high removal rate of pharmaceutical compounds (higher than 70%). Diuron removal was also mainly due to the Tertiary Treatment (50% elimination). Environmental performance of this Tertiary Treatment was assessed thanks to a life cycle analysis.

Baig, Marina CoqueryAbstract:Dissemination of chemical substances in the environment is becoming a major issue and wastewater effluents are one of the main point sources.

The groups of micropollutants monitored include pharmaceuticals, hormones pesticides (domestic uses) and also compounds listed in the WFD such as metals. Presented results show that with an ozone dosage of 5 g/m3, the Tertiary Treatment was able to eliminate pharmaceutical compounds, such as antibiotics and betablockers, achieving removal efficiencies higher than 70%. Regarding pesticides, only diuron and AMPA were quantified in the secondary effluent and both were greatly removed by the Tertiary Treatment (60 and 80%). Majority of the studied substances were removed by ozonation stage. This study also permits to highlight the positive effect of this Tertiary Treatment (especially the ozonation stage) for the removal of refractory micropollutants usually remaining in the effluent released by conventional physical and biological Treatments.

Xenobiotics removal by adsorption in the context of Tertiary Treatment: a mini review
Environmental Science and Pollution Research, 2013Co-Authors: Alexandre Tahar, Jean-marc Choubert, Marina CoqueryAbstract:Many xenobiotics, including several pharmaceuticals and pesticides, are poorly treated in domestic wastewater Treatment plants. Adsorption processes, such as with activated carbons, could be a solution to curb their discharge into the aquatic environment. As adsorbent-like activated carbon is known to be expensive, identifying promising alternative adsorbent materials is a key challenge for efficient yet affordable xenobiotic removal from wastewaters. As part of the effort to address this challenge, we surveyed the literature on pharmaceutical and pesticide xenobiotics and built a database compiling data from 38 scientific publications covering 65 xenobiotics and 58 materials. Special focus was given to the relevance and comparability of the data to the characteristics of the adsorbent materials used and to the operating conditions of the batch tests inventoried. This paper gives an in-depth overview of the adsorption capacities of various adsorbents. The little data on alternative adsorbent materials, especially for the adsorption of pharmaceuticals, makes it difficult to single out any one activated carbon alternative capable of adsorbing pesticides and pharmaceuticals at the Tertiary stage of Treatment. There is a pressing need for further lab-scale experiments to investigate the Tertiary Treatment of discharged effluents. We conclude with recommendations on how future data should best be used and interpreted.

life cycle assessment case study Tertiary Treatment process options for wastewater reuse
Integrated Environmental Assessment and Management, 2017Co-Authors: Erwan Carre, Joana Beigbeder, Vincent Jauzein, Guillaume Junqua, M LopezferberAbstract:: Tertiary Treatment process (including filtration and/or disinfection) is necessary to obtain a water quality suited for high-quality reuse from wastewater Treatment. Industrial pilots representing small real-size Treatment units were set up downstream of a conventional secondary Treatment of a wastewater Treatment plant in the South of France and their performance followed for 2 y. Life cycle assessment (LCA) methodology is used to compare the environmental impacts of different Treatment processes. Five Tertiary Treatment trains were studied: 1) sand filtration (SF) + storage followed by ultraviolet (UV) dynamic reactor disinfection (SF-UVD), 2) sand filtration + UV batch reactor disinfection (SF-UVB), 3) ultrafiltration (UF), 4) ultrafiltration and UV batch reactor disinfection (UF-UVB), and 5) microfiltration (MF) and storage followed by dynamic UV disinfection (MF-UVD). The chosen functional unit is "To supply 1 m3 of water with a quality in compliance with the highest standard of the French reuse regulations." The combination of SF with UV disinfection or the use of UF alone was found to be equivalent in terms of environmental impact for most of the midpoint indicators chosen. Combination of UF with UV disinfection was significantly more impacting because the electricity consumption was nearly doubled. This study was conducted on an industrial pilot; it may thus be representative of industrial facilities implemented to treat higher water flows.

technical economic and environmental assessment of coagulation filtration Tertiary Treatment processes in full scale wastewater Treatment plants
Journal of Cleaner Production, 2018Co-Authors: Dan Wang, Fang GuoAbstract:Abstract The technical performance, economic cost and environmental impact of six full-scale Tertiary coagulation/filtration processes located in Kunming, China were evaluated. All Tertiary Treatment processes removed total phosphorus (TP) and total suspended solids (TSS) efficiently, with the removal percentages of 55.0%–80.0% and 50.0%–74.0%, respectively. Polyaluminium chloride (PAC) consumption for TP and TSS removal in the six Tertiary Treatment processes were quite different, with chemical dosages of 7.9–38.5 g PAC/g TP removed and 0.3–1.7 g PAC/g TSS removed, respectively. The multiple linear regression analysis showed that the PAC dosage closed to the optimal value benefited TP and TSS removal, and this also reduced the economic cost. For environmental impacts, the main source of greenhouse gas was electricity consumption and the coagulation/filtration process had positive effect on reducing eutrophication. The comprehensive assessment including technical, economic and environmental aspects was characterized by the composite cost index. The composite cost index showed that the Tertiary Treatment process of micro-flocculation with D type/cloth media filtration achieved the best comprehensive performance, while D type filter had great potential for energy saving and chemical reduction.

new approach to solar photo fenton operation raceway ponds as Tertiary Treatment technology
Journal of Hazardous Materials, 2014Co-Authors: Irene Carra, Sixto Malato, Lucas Santosjuanes, Francisco Gabriel Acien Fernandez, Jose Antonio Sanchez PerezAbstract:The photo-Fenton process has proven its efficiency in the removal of micropollutants. However, the high costs usually associated with it prevent a spread of this technology. An important factor affecting costs is the kind of photoreactor used, usually tubular with a reflecting surface. Tubular reactors like compound parabolic collectors, CPCs, involve high capital costs. In comparison, the application of less costly reactors such as the extensive raceway ponds (RPRs) would help to spread the use of the photo-Fenton process as Tertiary Treatment at commercial scale. As far as the authors know, RPRs have never been used in advanced oxidation processes (AOPs) applications. This work is aimed at studying the applicability of RPRs to remove micropollutants with solar photo-Fenton. For this purpose, a pesticide mixture of commercial acetamiprid (ACTM) and thiabendazole (TBZ) (100μg/L each) was used in simulated secondary effluent. Iron concentration (1, 5.5 and 10mg/L) and liquid depth (5, 10 and 15cm) were studied as process variables. TBZ was removed at the beginning of the Treatment (less than 5min), although ACTM removal times were longer (20-40min for the highest iron concentrations). High Treatment capacity per surface area was obtained (48mg/hm(2) with 5.5mg Fe/L and 15cm liquid depth), proving the feasibility of using RPRs for micropollutant removal.

Tertiary Treatment of pulp mill wastewater by solar photo-Fenton.
Journal of hazardous materials, 2012Co-Authors: Marco S Lucas, José A Peres, Carlos Amor, Lucía Prieto-rodríguez, Manuel I Maldonado, Sixto MalatoAbstract:This work reports on pulp mill wastewater (PMW) Tertiary Treatment by Fenton (Fe(2+)/H(2)O(2)) and solar photo-Fenton (Fe(2+)/H(2)O(2)/UV) processes in a pilot plant based on compound parabolic collectors (CPCs). Solar photo-Fenton reaction is much more efficient than the respective dark reaction under identical experimental conditions. It leads to DOC mineralisation, COD and total polyphenols (TP) removal higher than 90%. The solar photo-Fenton experiment with 5mg Fe L(-1) reaches 90% of DOC mineralisation with 31kJ L(-1) of UV energy and 50mM of H(2)O(2). The initial non-biodegradability of PMW, as shown by respirometry assays and BOD(5)/COD ratio, can be changed after a solar photo-Fenton Treatment. Experiments with 20 and 50mg Fe L(-1) revealed that solar photo-Fenton can reach the same DOC degradation (90%), however, consuming less H(2)O(2) and time. Diluting the initial organic load to 50% also diminishes the dosage of H(2)O(2) and the necessary reaction time to achieve high DOC removals. Accordingly, solar photo-Fenton can be considered an alternative or complementary process to improve the performance of a biologic Treatment and, subsequently, achieve legal limits on discharge into natural waters.
