Available in PDF, EPUB and Kindle. Book excerpt: Laboratory studies were performed to determine if the addition of iron oxides throughout biosand filter (BSF) media would increase virus removal due to adsorption. The proposed mechanism is electrostatic adsorption of negatively charged virion particles to positively charged iron oxides formed during the corrosion of zerovalent iron. Initial tests conducted using continuous flow, small-scale glass columns showed high MS2 bacteriophage removal in an iron-amended sand column (5-log10) compared to a sand only column (0.5-log10) over 20 pore volumes. Additionally, two experiments with a column containing iron particles revealed 4 and 5 log10 removal of rotavirus in the presence of 20 mg/L total organic carbon. Full-scale BSFs with iron particles removed >4-log10 MS2 for the duration of the experiment (287 days), while BSF with steel wool removed >4-log10 MS2 for the first 160 days. Plug flow for the BSF was shown to depend on uniformity between the iron oxide material and sand media grains. The results suggest that the duration of effective virus removal by iron-amended biosand filtration depends on source water conditions and the quantity and composition of iron material added. Overall, this study provides evidence that iron-amended BSFs may advance the field of point-of-use technologies and bring relief to millions of people suffering from waterborne diseases.

Book excerpt: This book reviews principles, techniques and applications of metal, metal oxides, metal sulfides and metal-organic frameworks for removal and degradation of pollutants. Natural materials are often much more advanced than synthetic materials in terms of circularity and are functional, often biodegradable, recyclable and generate little waste. They are, therefore, a source of inspiration for new synthetic materials. In particular, recent research has focused on various types of functional materials such as organic, inorganic, nanostructured and composites for the remediation of environmental pollution.

Available in PDF, EPUB and Kindle. Book excerpt: Waterborne viruses are of great concern regarding drinking water safety because they are not always effectively removed by water treatment processes such as filtration and chlorination. Iron (oxyhydr)oxides are known to remove viruses from water, which suggests the potential of using zerovalent iron (ZVI) as a precursor of iron oxides to remove waterborne viruses. In this study, the mechanisms for virus removal and inactivation by ZVI and effect of dissolved organic matter (DOM) on the removal of viruses by ZVI were investigated through batch and column experiments using two bacteriophages, [straight phi]X174 and MS2, as model viruses. Batch experimental results indicated that removal of viruses from water by ZVI under anaerobic conditions was achieved through interactions of viruses with iron corrosion products, including aqueous Fe(II) and magnetite. Aqueous Fe(II) inactivated [straight phi]X174 but had no effect on MS2. Magnetite removed both viruses, where the removal of MS2 was mainly via reversible sorption, and for [straight phi]X174 the removal was due to both inactivation (or irreversible sorption) and reversible sorption. Column experimental results showed that DOM decreased virus removal by ZVI and that this effect was much more significant at 2.41 ppm dissolved organic carbon (DOC) compared to 0.34 ppm DOC. Competitive adsorption of DOM for the same adsorbing sites of iron corrosion products and DOM-facilitated virus transport are likely mechanisms responsible for the decreased virus removal observed in this study. Results from this study suggest that removal and inactivation of viruses by ZVI occur through multiple mechanisms involving different iron species, such as Fe(II) and magnetite. Different viruses may ix interact with iron species differently and hence are susceptible to inactivation to different extents. When ZVI is applied as a medium to treat viruses in water, pretreatment of DOM needs to be conducted to minimize its adverse effect on virus removal efficiency of ZVI.

Available in PDF, EPUB and Kindle. Book excerpt: Microbiology of Drinking Water Production and Distribution addresses the public health aspects of drinking water treatment and distribution. It explains the different water treatment processes, such as pretreatment, coagulation, flocculation, sedimentation, filtration, disinfection, and their impacts on waterborne microbial pathogens and parasites. Drinking water quality may be degraded in water distribution systems—microorganisms form biofilms within distribution systems that allow them to flourish. Various methodologies have been proposed to assess the bacterial growth potential in water distribution systems. Microbiology of Drinking Water Production and Distribution also places drinking water quality and public health issues in context; it addresses the effect of bioterrorism on drinking water safety, particularly safeguards that are in place to protect consumers against the microbial agents involved. In addition, the text delves into research on drinking water quality in developing countries and the low-cost treatment technologies that could save lives. The text also examines the microbiological water quality of bottled water, often misunderstood by the public at large.

Available in PDF, EPUB and Kindle. Book excerpt: This book argues, that without methods, there can be no research. Effective research requires effective methods, not always easy to come by. The development of methods in environmental virology became a focus of growing interest about two decades ago. Progress has been significant since that time in pure experimental systems, where there are no interferences, consistent high recoveries of viruses from environmental waters has been achievable for some time. In the natural environment, however, in relatively clean waters, substances such as humic and fulvic acids interfere with viral recoveries and average recovery rates probably do not reach 20%. With sewage sludges and shellfish, recoveries are undoubtedly much lower. Yet, even relatively low viral recovery rates have made possible the detection of viral hazards in drinking waters. The hazards that exist are undoubtedly much greater than those demonstrated with the relatively inefficient methods inefficient methods developed thus far. Improving methods, as they are developed in the years to come, will undoubtedly bring the true extent of the hazards into better perspective.

Book excerpt: The NATO Advanced Research Workshop "Role of Interfaces in Environmental Protection" has been held on May 27-30, 2002 in Miskolc, Hungary, under leadership of co-directors Prof Sandor Barany from the University ofMiskolc, Hungary, and Prof Nataliya Klymenko, National Academy of Sciences of Ukraine. The objective of the ARW was to highlight colloidal and biocolloidal aspects of environmental pollution and technologies to monitor, remediate, abate and prevent pollution. It is known that the solution of majority of environmental problems is closely connected with phenomena at the interfaces. The behaviour, transport of dispersed particles in the environment, the main phase separation methods in water treatment, purification of liquids, aerosols removal, many soil remediation processes as well as the methods of protection of human organisms from hazardous matters, are based on concepts of colloid chemistry, i.e. properties of interfaces and their behaviour in different media. Examples of these methods are: filtration, ultrafiltration, flotation, coagulation, hetero-coagulation and flocculation, adsorption, adhesion of micro-organisms to surfaces, membrane separation methods, etc. A very important and special aspect of the topic is the human protection using colloid-chemical approaches, i.e. the adsorption, aggregation and adagulation properties of differe~t materials. Examples are: adsorption of hazardous organic materials, drugs, heavy· metals and radionuclides on activated carbon, silica, cellulose derivatives, etc.
