Ultrasonic sludge disintegration in the presence of iron (II) as catalyst

引用

International Journal of Environment and Waste Management 2013年第1期12卷 65-76页

作者： Rai, Chockalingam Lajapathi Sivasamy, Arumugam Rekha, Subramani Process Development and Scale-up Group Chemical Engineering Division Central Leather Research Institute Adyar Chennai 600020 India

Increasing environmental awareness worldwide and subsequent regulations have led to the application of improved and novel technologies in excess sludge treatment. Sludge is the by-product of wastewater treatment plants rich in organic carbons, pathogens and metals. To enhance the ultrasonic sludge disintegration, a new method by introducing (Fe (II)) as a catalyst in the process has been explored. Studies were conducted to elucidate the parameters governing the disintegration process. The disintegration profiles show two phases distuption of micro-organisms resulting release of organic-substances and mineralisation of dissolved organic substances. The optimal level of process parameters results in better solubilisation and mineralisation. © 2013 Inderscience Enterprises Ltd.

Energy use and greenhouse gas (GHG) emissions associated with life cycle stages of road infrastructure are currently rarely assessed during road infrastructure planning. This study examines the road infrastructure planning process, with emphasis on its use of Environmental Assessments (EA), and identifies when and how Life Cycle Assessment (LCA) can be integrated in the early planning stages for supporting decisions such as choice of road corridor. Road infrastructure planning processes are compared for four European countries (Sweden, Norway, Denmark, and the Netherlands). The results show that only Norway has a formalised way of using LCA during choice of road corridor. Only the Netherlands has a requirement for using LCA in the later procurement stage. It is concluded that during the early stages of planning, LCA could be integrated as part of an EA, as a separate process or as part of a Cost-Benefit Analysis. © 2014 Imperial College Press.

A commercial hydrotreating nickel molybdate/alumina catalyst was used for the direct conversion of natural gas (NG) into CO_x-free hydrogen and a co-valuable product of multi-walled carbon nanotubes (MWCNTs). The catalytic runs were carried out atmospherically in a fixed-bed flow reactor. The effect of reaction temperature between 600 and 800 °C, and dilution of the NG feed with nitrogen as well as pretreatment of the catalyst with hydrogen were investigated. At a reaction temperature of 700 °C and dilution ratio of NG/N₂ = 20/30, the optimum yield of H₂ (∼80%) was obtained with higher longevity. However, using the feed ratio of NG/N₂ = 30/20, the optimum yield of MWCNTs was obtained (669%). X-ray diffraction pattern for the catalyst after the reaction showed that the MWCNTs were grown on the catalyst at all reaction temperatures under study. TEM pictures revealed that the as-grown MWCNTs at 600, 650 and 800 °C are short and long with a low graphitization degree. At 700 °C a forest of condensed CNTs is formed, whereas both carbon nanofibers and CNTs were formed at 750 °C. © 2012

IOP Conference Series: Earth and Environmental Science 2014年第3期22卷

Introduction of intermittent electricity production systems like wind power and solar systems to electricity market together with the consumption-based electricity production resulted in numerous start/stops, load variations and off-design operation of water turbines. The hydropower systems suffer from the varying loads exerted on the stationary and rotating parts of the turbines during load variations which they are not designed for. On the other hand, investigations on part load operation of single regulated turbines, i.e., Francis and propeller, proved the formation of rotating vortex rope (RVR) in the draft tube. The RVR induces oscillating flow both in plunging and rotating modes which results in oscillating force with two different frequencies on the runner blades, bearings and other rotating parts of the turbine. The purpose of this study is to investigate the effect of transient operations on the pressure fluctuations on the runner and mechanism of the RVR formation/mitigation. Draft tube and runner blades of the Porjus U9 model, a Kaplan turbine, were equipped with pressure sensors. The model was run in off-cam mode during different load variation conditions to check the runner performance under unsteady condition. The results showed that the transients between the best efficiency point and the high load happens in a smooth way while transitions to/from the part load, where rotating vortex rope (RVR) forms in the draft tube induces high level of fluctuations with two frequencies on the runner; plunging and rotating mode of the RVR.

International Journal of Environmental engineering 2013年第2期5卷 208-227页

作者： Rai, Chockalingam Lajapathi Raghav, Madhumitha Surianarayanan, Mahadevan Sreenivas, Vemulapalli Process Development and Scale-up Group Chemical Engineering Division Central Leather Research Institute Adyar Chennai - 600 020 India Chemical Engineering Division Central Leather Research Institute Adyar Chennai - 600 020 India Cell for Industrial Safety and Risk Analysis Chemical Engineering Division Central Leather Research Institute Adyar Chennai - 600 020 India

The objective is to study the effect of certain parameters on the degradation rate of the dye CI acid blue 113 by cavitation processes. Kinetic models have been developed and validated for ultrasonic and hydrodynamic cavitation treatment with hydrogen peroxide to enhance oxidation. The magnitude of effect of the reaction parameters in acoustic cavitation for geometric ratio, pH, ultrasonic density, initial dye concentration and hydrogen peroxide concentration were -0.4370, -1.2455, 0.1140, -0.3741 and 0.2788. In the case of hydrodynamic cavitation, values for initial dye concentration, pH, inlet pressure, power density and hydrogen peroxide concentration were -0.2562, -0.1494, 0.4556, 0.4807 and 0.1681. Finally, the energy efficiencies of the two processes have been compared. Hydrodynamic cavitation was found to be energy efficient than acoustic cavitation. © 2012 Inderscience Enterprises Ltd.

New titanium alloys have been developed for use in next-generation aircrafts by adding low-cost elements such as C, Fe, Al and Cr. Some of the newly developed alloys are Ti-4.5Al-2Mo-1.6V-0.5Fe-0.3Si-0.03C, referred to as KS Ti-9, and Ti-4.5Al-2.5Cr-1.2Fe-0.1C, referred to as KS Ti-531C. As opposed to the widely used Ti-6Al-4V (Ti64), KS Ti-9 can be rolled at much lower temperatures without employing pack-rolling, and the anisotropy in its mechanical strength is significant. Microstructural control process to reduce the anisotropy in the mechanical strength of KS Ti-9 has been investigated. Anisotropy controlling treatment (ACT) is found to be effective to reduce the anisotropy in the mechanical strength of KS Ti-9. KS Ti-531C, with good mechanical properties at room temperature, similar to those of Ti64, and high hot-workability with low flow stress during deformation at high temperatures, similar to that of commercially pure titanium (CPTi), has been developed for fabricating forged or extruded components. There still exists a possibility of the precipitation of titanium carbides depending on the kind of the microstructural control process used. The mechanical properties and the fatigue strength of KS Ti-531C with different microstructures have been investigated, (α + β)-annealed KS Ti-531C with an equiaxed α structure exhibits better ductility and fatigue strength than β-annealed KS Ti-531C with the Widmanstätten α structure because of the presence of titanium carbide precipitates in the β-annealed KS Ti-531C.

It is widely acknowledged that environmental literacy, in the early stages of education, can provide a strong foundation for future environmental behaviours, as well as help in the transition towards more sustainable societies. This paper is based upon an evaluation of the environmental attitudes of students in a primary school in rural Slovenia. The attitudes were assessed according to the students' behaviours in their family (primary) and school (secondary) and family contexts. The results show that traditional teaching, in this school, accounts for only one-third of the recognised factors that influence the students' environmental behaviours. The other factors that foster environmental behaviours include the primary and secondary social environments, the structural and infrastructural condition in the school, and gender, where emotional attitudes play a key role. The authors suggest that, in order to more adequately address the gap between learning and acting, school administrators, teachers, parents, and other stakeholders should integrate an array of sustainability issues throughout formal and informal efforts so as to more effectively encourage the development of positive environmental attitudes, and behaviours among their youth and among themselves as role models. Additionally, school principals are urged to improve infrastructural and structural, attitudinal and procedural parameters at the schools, and to change the curricula in order to foster pro-environmental behaviours. © 2011 Elsevier Ltd.
