  • Characteristics of pipe-scale in the pipes of an urban drinking water distribution system in eastern China

    Pipes that carry drinking water have gradually aged. Events occurring with increasing frequency, such as substandard water quality in residential taps, red water, and black water, reveal the deterioration of the chemical stability of a drinking water distribution system (DWDS). Pipes in the DWDS serving City S, located in eastern China, were sampled to analyze the concentration and ...

  • Haloacetic acid degradation by a biofilm in a simulated drinking water distribution system

    Haloacetic acids (HAAs) are disinfection by-products formed as a result of the reaction between chlorine and natural organic matter found in water. HAA concentrations have been observed to decrease at distribution system extremities. This decrease is associated with microbiological degradation by pipe wall biofilm. The objective of this study was to evaluate HAA degradation in a drinking water ...

  • Accumulated CFC-11 in polyurethane foam insulation: an estimate of the total amount in district heating installations in Sweden

    In rigid polyurethane foam used for thermal insulation, CFC-11 has been the main blowing agent for many years, but is now subject to phase-out regulations. During ageing of this foam, air diffuses into it and blowing agents leak into the atmosphere, resulting in a decreased insulating capacity. Determinations of the cell gas composition and the total content of CFC-11 in foam from district ...

  • Design and Operational Considerations to Avoid Excessive Anaerobic Digester Foaming

    Excessive foaming in anaerobic digesters has been a problem for many years. All anaerobic digesters will foam to some extent, but excessive foam can be problematic. Excessive foaming is defined as foam that interferes with flow through the gas piping system and/or is not contained within the digester. Causes of foaming include presence of excessive filamentous bacteria, extreme amounts of oils ...

  • Impact of plumbing age on copper levels in drinking water

    Theory and practical experiences suggest that higher copper levels in drinking water tap samples are typically associated with newer plumbing systems, and levels decrease with increasing plumbing age. Past researchers have developed a conceptual model to explain the ‘aging effect’ founded in the proposed evolution of copper(II) corrosion by-products on the pipe surface, based on theoretical ...

  • Response of epilithic diatom assemblages to urbanization influences

    Urbanization has long been recognized to alter the hydrology, water quality and channel form of waterways. Recently, consideration of urban impacts on waterways has expanded to include assessment of the aquatic biota, generally focusing upon the macroinvertebrate fauna. This study compares the impacts of urbanization on the structure of stream benthic diatom communities in 16 first- and ...

  • Lysimeter comparison of the role of waste characteristics in the formation of mineral deposits in leachate drainage systems

    A common operational problem in leachate collection systems is clogging due to the formation of deposits within pore spaces and collection pipes. The role of co-disposal of municipal solid waste (MSW) and combustion residues from waste-to-energy (WTE) facilities in clogging is evaluated in this paper. Five parallel lysimeters were operated in monofill or co-disposal mode using MSW, WTE combustion ...

  • What is water? A normative perspective

    In the modernist era, water is discussed as a single substance which has multiple uses. I argue that from a normative perspective water should be discussed in the plural term (‘waters’), as they constitute a variety of ‘things’ with a similar chemical composition. Waters are composed of multiple ‘needs’, which are uses with a normative rationale, and of ‘wants’, which are desires that should be ...

  • Hydrogel floc nature and biogenic constituents of drinking water discolouration deposits

    Loose deposits (LD) develop and accumulate in drinking water distribution systems' (DWDS) pipes and often lead to discolouration incidents, which are a major reason for customers' complaints. In addition, LD may accumulate contaminants, while discolouration may be accompanied by degradation of the water's microbiological quality. Along with iron oxides, organic compounds are ...
