Global environmental pollution is recognized as a serious problem that motivates the development of new technologies and mitigation of emissions from current ones. The civilian, commercial, and defense sectors of most advanced industrialized nations are facing problems related to remediation of hazardous wastes, contaminated soils and groundwater. In this communication, we describe results of a study indicating that the photo-efficiency of electrochemically grown porous TiO2-catalyst can be dramatically enhanced by an electrochemical approach that enables the development of a highly efficient water purification system. The dramatic efficiency enhancement of this process arises from deep understanding of the nature of TiO2-catalyst; intense and extreme electrochemical polarization would totally eliminates electron/hole pair recombination process, which is primary factor affecting photo-catalysis efficiency. Elimination of more than 99.9999% of E.coli bacteria (5–6 orders of magnitudes of inactivation) within 6 h was achieved by the use of this approach. It was found that immobilized grown porous TiO2-catalyst can repeatedly be used, achieving extremely high efficiency, without any need for regeneration or highly advanced filtration techniques for the removal of the TiO2 such as in the powder technology. 2007 Elsevier B.V.

The present study demonstrates different approaches towards MIC identification in three real cases of technological equipment failures. In the first case the failure of carbon steel heat exchanger as a result of tubes, lids, tube sheets, and connection pipes clogging was investigated. Chemical analysis of cooling water and precipitates, as well laboratory screening of deposits for bacteria, revealed that activity of iron-oxidizing bacteria present in cooling water led to heat exchanger blockage. The second case is related to MIC detection on floating roofs made of magnesium–aluminum alloy following a 3-weeks hydro-test. Corrosion tests carried out on the original and sterilized water used in hydro-test confirmed MIC process. In the third case the potential of MIC occurrence in engine cooling system made of cast aluminum alloy and filled with 20% ethylene glycol coolant solution was evaluated. The simulation tests allowed determining the real causes of the severe corrosion attack of examined system, including MIC high probability. 2007 Elsevier Ltd. All rights reserved.
Bacteriophage ecology in a small community sewer system related to their indicative role in sewage pollution of drinking water

In view of various studies looking for the merit of coliphages as indicators of water pollution with viruses originating from faecal material, a small agricultural community (population of approximately 1500 inhabitants of all ages, 2–3 km from Haifa) was selected in order to understand these bacteriophage ecology (F-RNA and somatic coliphages) in its sewer and oxidation pond system. Along the sewer lines, it was possible to isolate constantly both bacteriophage types (F-RNA and somatic coliphages) at 102-104 plaque-forming units (pfu) ml-1. The average numbers of somatic and F-RNA phages isolated from oxidation pond were 103-104 pfu ml-1; however, somatic coliphages were undetectable for several months (April–August). Significant high correlation (0.944 < R2 < 0.99) was found between increased anionic detergent concentrations and F-RNA coliphage numbers. Infants less than 1 year old excreted both phage types and few only F-RNA coliphages (at high numbers > 105 pfu g-1) for up to 1 year. The excretion of F-RNA coliphages was highly linked to Escherichia coli F+ harborage in the intestinal track as found in their faecal content. Finally, three bacterial hosts E. coli F+, F– and CN13 tested for survivability in sewage filtrate revealed that E. coli F+ had the highest survivability under these conditions. Presence of somatic and F male-specific phages in sewer lines of a small community are influenced by several factors such as: anionic detergents, nutrients, temperature, source (mainly infants), shedding and survival capability of the host strain. Better understanding of coliphages ecology in sewer systems can enhance our evaluation of these proposed indicator/index microorganisms used in tracking environmental pollution of water, soil and crop contamination with faecal material containing enteric viruses.
