  • Pathogen Inactivation by a Closed Alakaline System

    ABSTRACTThe efficiency of advanced alkaline disinfection in closed systems has been demonstrated to depend on the balance of ammonia concentration, pH, exposure time, temperature, total solids content, post-treatment storage time and mixing effectiveness. When the alkaline system is a closed one, an additional pathogen stressor is added: pressure. The effect of the alkaline dosing has been ...

  • Water for Southern California: water resources development at the close of the century.

    INTRODUCTION In 1999, California observes the 150th year of the Gold Rush.

  • Solar hot water system

    Solar hot water systems (e.g. residential) do not produce steam, for example. Thus, solar hot water systems cannot push a steam turbine and will not generate electrical power. Solar hot water systems are used for heating and hot water requirements, not electrical power. If this is offsetting electrical hot water or electrical heat, then these are more like 'negawatts' than Terawatts. Steam ...

  • Methodology for Forensic Investigation of Potable Water Quality in Municipal Distribution Systems

    Abstract During routine regulatory potable water quality sampling in distribution systems related to the Total Coliform Rule, utilities can sometimes experience anomalous detections of total coliform bacteria and/or fecal coliform bacteria in the distribution system samples. Frequently, the regulatory-required retesting of the same sample locations reveals no detection of bacteria, and thus ...

  • Removal of bacteria, protozoa and viruses through a multiple-barrier household water disinfection system

    Municipal water disinfection systems in some areas are not always able to meet water consumer needs, such as ensuring distributed water quality, because household water management can be a contributing factor in water re-contamination. This fact is related to the storage options that are common in places where water is scarce or is distributed over limited time periods. The aim of this study is ...
