Integration of Environmental and Economic Performance of Processes. Case Study on Advanced Oxidation Processes for Wastewater Treatment
Authors: Muñoz Ivan , Malato Sixto , Rodríguez Amadeo , Domènech Xavier 
Published: November 2016

AbstractThe aim of this paper is to introduce an easy-to-use environmental-economic index (EEI) which can be used for comparative purposes when assessing processes and services. The EEI differs from traditional ratiobased Eco-efficiency indicators, since it is defined instead as the sum of two components, one corresponding to environmental performance and the other to economic performance. In order to show the calculation of this index and its potential usefulness, it is used in an example where several Advanced Oxidation Processes (AOPs) for wastewater treatment are compared based on their life-cycle greenhouse gas emissions and life-cycle cost. The options assessed are: solar-driven photo-Fenton, lamp-driven photo-Fenton, and ozonation. Solar-driven photo- Fenton appears as the preferable option from an integrated environmental-economic point of view, if the environmental and economic dimensions are equally weighed. The case study shows that EEI captures, in a single score, both environmental and economic information from a given set of alternative options, allowing us to assess their relative performance in a simple way.

Published: November 2016

AbstractThe ozonation of landfill leachates in a bubble column was investigated concerning the effect of operating parameters, such as initial organic loading (from 550 to 5500 mg/L dissolved COD), reaction time (from 60 to 360 min) and ozone gas phase concentration (from 19 to 38 mg/L) on treatment efficiency implementing a factorial experimental design. All three parameters tested, as well the second order interaction between initial COD and ozone had a statistically significant, positive impact on COD removal. At increased COD loadings and a maximum ozone concentration of 38 mg/L, COD was the single most important factor affecting both COD and phenols removal. Treatment of the raw leachate (5500 mg/L COD) for 360 min and maximum ozone concentration led to 50% COD removal with a first-order kinetic constant of 2.2 10

Published: November 2016

AbstractThe photocatalytic degradation of 4-nitrophenol in aqueous solution was performed by using a continuous fixed bed annular photoreactor. Titanium dioxide was used as the photocatalyst, supported as thin film on Pyrex glass beads. The influence of different operative parameters as substrate and oxygen concentrations, volumetric flow rate and incident photonic flow on the kinetics was studied. The Langmuir-Hinshelwood model has been satisfactorily fitted to the experimental results and its parameters have been determined. The true value of the kinetic constant can not be determined as the model contains a parameter very difficult to be measured, i.e. the total surface area active for the occurrence of photoreaction.

Authors: Baciocchi Renato , Ciotti Cesare , Cleriti Giacomo , Innocenti Ivan , Nardella Alessandro 
Published: November 2016

AbstractCriteria for the design of In-Situ Fenton Oxidation (ISFO) is proposed and applied to the development of a pilot-scale treatment of a former refinery site contaminated by hydrocarbons. The proposed criteria takes in account both the regulatory and technical constraints that typically characterize the application of in situ remediation technologies. The proposed design strategy of the ISFO treatment is based on coupling experimental and numerical modelling of the ISFO treatment in an iterative way. Batch tests are performed first, allowing to select the optimal operating conditions and the data on hydrogen peroxide decomposition kinetics. These data, together with the hydro-geological information collected in the field, are then used for the numerical modelling of the ISFO treatment, which allows to define the pilot plant layout and operating conditions and to evaluate the effective delivery of the oxidant and the hydraulic gradient developed in the field. These data are then used to design column scale tests aimed to evaluate the effective hydrogen peroxide longevity, the process performance and the extent of gas production from hydrogen peroxide decomposition.
Carbon-modified TiO2 as Photocatalysts
Authors: Janus Magdalena , Morawski Antoni W. 
Published: November 2016

AbstractPhotocatalysis belongs to one of the Advanced Oxidation Processes (AOP). These processes make possible the decomposition of organic compounds to carbon dioxide and water. The most useful photocatalyst is titanium dioxide which, to make it active, requires irradiation with suitable wavelengths. Pure titanium dioxide can be activated only by ultraviolet light irradiation (UV). For a long time, studies have been carried on modified titanium dioxide materials to obtain more effective photocatalysts with greater activity under UV light irradiation or to obtain photocatalysts which may be active also under visible light irradiation. One of the possible ways for modifying TiO

Published: November 2016

AbstractThe major part of the regulated priority substances and family of compounds defined in the European Water Framework Directive and some other organic micropollutants were tracked in a municipal biotreated secondary effluent. Micropollutants detected in the effluent were subjected to different ozone doses related to different oxidation extents. Ozone confirmed its efficiency in terms of micropollutant reduction when applied to a municipal biotreated effluent. Accordingly, it achieved reductions exceeding 70% for 91% of the pollutants detected at high ozone dose. Organic matter transformation was also investigated by both controlling evolution of surrogates - including chemical oxygen demand, dissolved organic carbon, UV

Published: November 2016

AbstractLow temperature, non-equilibrium plasma was generated during gliding arc discharge in a multi-electrode reactor at atmospheric pressure. Various diagnostic methods to determine electrons and gas temperature were used. Hot electrons’ temperature has been determined by optical spectroscopy. In the case of gas temperature, which is much lower, it was determined directly by the thermovision camera to avoid tedious calculations from the spectral lines. The results of the plasma diagnostics generated by gliding arc for different process gases and their flow rates are presented and discussed. Simplified diagnostic method would be very perspective for monitoring of various technological processes where plasma is used such as treatment of flue gases, wastes utilization, deodorization, disinfection and sterilization, material processing and new material manufacturing for application in microelectronics and nanotechnologies.

Published: November 2016

AbstractOne of the most effective method of contaminated soil utilization is thermal plasma arc treatment. Assuming that electric arc is immersed under the ground level - it is placed only in mineral atmosphere. Components from utilized soil are the source of these minerals. A furnace with the immersed arc-plasma has been elaborated for solid waste treatment purposes. To establish the influence of particular minerals on the discharge, a model where particular elements can penetrate the arc plasma channel has been made. The discharge takes place in a mineral atmosphere, similarly to the immersed arc plasma waste utilization. Subsequently, the arc temperature was measured. A measurement based on the two spectral lines method with Abel inversion, independent of the plasma chemistry was used. A new utilization method of soil wastes using an immersed arc with efficiency up to 98% has been described. Experimental results from the research has been presented and mineral plasma composition has been calculated and compared.
Landfill Leachate Treatment by Fenton, Photo-Fenton Processes and their Modification
Authors: Krzysztoszek Agata , Naumczyk Jeremi 
Published: November 2016

AbstractEfficiency of leachate treatment in Fenton, photo-Fenton processes and their modifications was studied. Process was modified by leachate acidification, followed by the precipitate separation and continuing the processes. Acidification to pH 2.0 and 3.0 led to 34.3% and 18.9% COD removal respectively. The efficiency of the processes was decreasing as follows: modified photo-Fenton pH 2.0 (96.5% COD removal) > photo-Fenton pH 2.0 (95.0%) > modified photo-Fenton pH 3.0 (89.2%) > photo-Fenton pH 3.0 (85.9%) > modified Fenton pH 2.0 (79.5%) > Fenton pH 2.0 (77.6%) > modified Fenton pH 3.0 (64.8%) > Fenton pH 3.0 (63.5%). At the beginning of the processes the coagulation contribution was higher (up to 73% of total COD removal), while finally it was exceeded by Fenton reaction contribution (up to 66% of total COD removal). Empirical formula for Fenton reaction kinetics was proposed.

Heterogeneous Catalytic Supercritical Water Oxidation of Refractory Organic Pollutants in Industrial Wastewaters
Authors: Guolin Jing , Mingming Luan , Tingting Chen 
Published: November 2016

AbstractCatalytic supercritical water oxidation (CSCWO) is one of the most environmental-friendly advanced oxidation process. It makes a promising technology for the treatment of refractory organic pollutants in industrial wastewaters. Various heterogeneous catalysts including metal oxides have been extensively studied to enhance the efficiency of CSCWO. The present review is concerned about the literatures published in this regard. Phenolics, carboxylic acids and N-containing compounds were taken as model pollutants in most cases, and oxides of Cr, Mn, Co, V, Cu, Zn, Al, Ti and Ce were applied as heterogeneous catalysts. Reports on their characterization and catalytic performances for the CSCWO of aqueous pollutants are reviewed. Discussions are also made on the reaction mechanisms and kinetics proposed for heterogeneous CSCWO.

Published: November 2016

AbstractPhotodegradation of p-cresol was carried out by a 1.0wt% Mn doped ZnO under visible light irradiation. The amount of photocatalyst, concentration of p-cresol and pH were studied as variables. The residue of p-cresol and mineralisation was measured using a UV-visible spectrophotometer and TOC analyzer, respectively. The intermediate was detected by UPLC. The results showed the amount of photocatalyst and concentration of p-cresol was 1.5g/L and 35 ppm respectively. P-cresol photodegradation was favorable in the pH 6-9 range. The detected intermediate was 4-hydroxy-benzaldehyde. TOC studies show that 74% of total organic carbon was removed from solution during irradiation time. Reusability shows no significant reduction in photocatalytic performance in photodegrading p-cresol. This study indicates that 1.0 wt% Mn doped ZnO can remove p-cresol from wastewater under visible light irradiation, and being more economic than UV irradiation could be applied on an industrial scale.
