Book Synopsis Bacteria and Virus Control by Electrochemical Coagulation and Microfiltration by : Charan Tej Tanneru
Download or read book Bacteria and Virus Control by Electrochemical Coagulation and Microfiltration written by Charan Tej Tanneru and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bench-scale experiments were performed to evaluate microorganism control by electrochemical coagulation and membrane microfiltration. Natural organic matter (NOM) present in natural waters appears to reduce the effectiveness of iron electrocoagulation pretreatment to microfiltration for MS2 virus control by complexing ferrous ions generated at the sacrificial anode during electrolysis. This inhibits (i) Fe2+ oxidation, precipitation, and virus destabilization and (ii) virus inactivation through reactive oxygen species intermediates or by direct interactions with Fe2+ ions. In contrast, higher reductions in MS2 virus concentrations were obtained when aluminum was electrochemically added to surface water. Sweep flocculation was the primary virus destabilization mechanism with secondary contributions from charge neutralization. Direct evidence for virus enmeshment in flocs was provided by two independent methods: quantitative elution using beef extract at elevated pH and quantitating fluorescence from labeled viruses. Monotonically increasing adhesion force between viruses immobilized on AFM tips and floc surfaces with increasing electrocoagulant dosage was measured by atomic force microscopy, which was accompanied by decreasing magnitude of the zeta potential (→ 0) and increasing NOM removal. Hence, virus uptake mechanisms also include charge neutralization and hydrophobic interactions with NOM on floc surfaces. Evidence for virus inactivation was also obtained during iron and aluminum electrocoagulation of synthetic water spiked with viruses. Free chlorine was produced during aluminum electrolysis of saline solutions via oxidation of chloride ions, which inactivated MS2 viruses. Capsid protein modifications probed using Fourier transform infrared spectroscopy (FTIR) revealed significant oxidative modification in amide I and II (1700-1500 cm-1) region. Evidence for genome damage was obtained using quantitative real time polymerase chain reaction (q-RT-PCR). Hence, alterations of capsid proteins and loss of genome structural integrity both contributed to inactivation. Separate experiments were performed to examine the rejection of spherical silica colloids and viruses as well as capsule-shaped bacteria by clean microfiltration membranes. Modeling efforts (performed by Prof. Ruth Baltus’ group at Clarkson University) focused on incorporating the convective hindrance factor for a capsule shaped particle in a cylindrical pore into predictions of the rejection coefficient. Short-term MF experiments were performed at the University of Houston to measure rejection of three Gram negative bacteria, two spherical viruses, and several spherical silica particles by a number of track-etched membranes with near cylindrical pore geometry in a stirred cell before the onset of fouling. Experimental rejections of spherical viruses, and particulate silica and several rod-shaped Gram negative bacteria with aspect ratio from 2 to 5 by clean track-etched membranes were in general agreement with theoretical predictions.

Book Synopsis Anaerobic Digestion Model No.1 (ADM1) by : IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes
Download or read book Anaerobic Digestion Model No.1 (ADM1) written by IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes and published by IWA Publishing. This book was released on 2002-02-01 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes was created with the aim to produce a generic model and common platform for dynamic simulations of a variety of anaerobic processes. This book presents the outcome of this undertaking and is the result of four years collaborative work by a number of international experts from various fields of anaerobic process technology. The purpose of this approach is to provide a unified basis for anaerobic digestion modelling. It is hoped this will promote increased application of modelling and simulation as a tool for research, design, operation and optimisation of anaerobic processes worldwide. This model was developed on the basis of the extensive but often disparate work in modelling and simulation of anaerobic digestion systems over the last twenty years. In developing ADM1, the Task Group have tried to establish common nomenclature, units and model structure, consistent with existing anaerobic modelling literature and the popular activated sludge models (See Activated Sludge Models ASM1, ASM2, ASM2d and ASM3, IWA Publishing, 2000, ISBN: 1900222248). As such, it is intended to promote widespread application of simulation from domestic (wastewater and sludge) treatment systems to specialised industrial applications. Outputs from the model include common process variables such gas flow and composition, pH, separate organic acids, and ammonium. The structure has been devised to encourage specific extensions or modifications where required, but still maintain a common platform. During development the model has been successfully tested on a range of systems from full-scale waste sludge digestion to laboratory-scale thermophilic high-rate UASB reactors. The model structure is presented in a readily applicable matrix format for implementation in many available differential equation solvers. It is expected that the model will be available as part of commercial wastewater simulation packages. ADM1 will be a valuable information source for practising engineers working in water treatment (both domestic and industrial) as well as academic researchers and students in Environmental Engineering and Science, Civil and Sanitary Engineering, Biotechnology, and Chemical and Process Engineering departments.

Available in PDF, EPUB and Kindle. Book excerpt: "Sanitation Safety Planning (SSP) is a step-by-step risk based approach to assist in the implementation of the 2006 WHO Guidelines for Safe Use of Wastewater, Excreta and Greywater in Agriculture and Aquaculture. The approach can be applied to all sanitary systems to ensure the system is managed to meet health objectives. SSP assists users to: systematically identify and manage health risk along the sanitation chain; guide investment based on actual risks, to promote health benefits and minimize adverse health impacts; provide assurance to authorities and the public on the safety of sanitation-related products and services. The SSP manual is targeted at a variety of users at different levels including; health authorities and regulators, local authorities, wastewater utility managers, sanitation enterprises and farmers, community based organizations, farmers associations and NGOs. SSP brings together actors from different sectors to identify health risks in the sanitation system and agree on improvements and regular monitoring and underscores the leadership role of the health sector."--Publisher's description.

Book Synopsis Electrochemistry for the Environment by : Christos Comninellis
Download or read book Electrochemistry for the Environment written by Christos Comninellis and published by Springer Science & Business Media. This book was released on 2009-10-15 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater treatment technology is undergoing a profound transformation due to the fundamental changes in regulations governing the discharge and disposal of h- ardous pollutants. Established design procedures and criteria, which have served the industry well for decades, can no longer meet the ever-increasing demand. Toxicity reduction requirements dictate in the development of new technologies for the treatment of these toxic pollutants in a safe and cost-effective manner. Fo- most among these technologies are electrochemical processes. While electrochemical technologies have been known and utilized for the tre- ment of wastewater containing heavy metal cations, the application of these p- cesses is only just a beginning to be developed for the oxidation of recalcitrant organic pollutants. In fact, only recently the electrochemical oxidation process has been rec- nized as an advanced oxidation process (AOP). This is due to the development of boron-doped diamond (BDD) anodes on which the oxidation of organic pollutants is mediated via the formation of active hydroxyl radicals.
