  • Odorant screening and possible origin analysis of odor episodes in one reservoir in northern China

    Odorous drinking water problem occurred repeatedly in one city in northern China in recent years. The uniqueness of this odor episode lay in two aspects: (1) the odorous chemicals were quite different from common odorants, such as geosmin and 2-MIB; and (2) it occurred repeatedly in different seasons during a time span of more than 2 years. The screening of odorants was the first and one of ...

  • Characterization of organic fouling in reverse osmosis membranes by headspace solid phase microextraction and gas chromatography–mass spectrometry

    Adsorption of organic substances on reverse osmosis (RO) membrane surfaces may form an organic film on the membrane, known as organic fouling, and cause flow-rate loss. This problem is mostly unavoidable as no pretreatment method exists for perfect removal of possible foulants, including organic compounds resulting from undesirable bioactivity. Understanding the characteristics of fouling layers ...

  • Quantitative Determination of Volatile Organic Compounds in Drinking Water by EPA Method with Headspace Trap GC-MS

    Volatile Organic Compounds (VOCs) refer to a group of easily vapourised organic compounds. Under atmospheric pressure, these compounds boil below 250C. Studies have shown that prolonged exposure to the VOCs could increase the risk of various health problems, such as cancer. VOCs are commonly present in gasoline, dry cleaning solvents and degreasing agents. Due to improper storage, disposal or ...

  • Behaviour of different cementitious material formulations in sewer networks

    Sewer networks are subjected to degradation, including biodeterioration of materials, in the presence of biogenic sulfuric acid, leading to costly repairs. To ensure durable structures, it is essential to select the best adapted materials. Two cementitious materials based on ordinary Portland cement (OPC) or calcium aluminate cement (CAC), were subjected to biodeterioration in the headspace of ...

  • Determination of Bisphenol A in Drinking Water

    A comprehensive sample preparation and analytical procedure was developed for determining BPA in drinking water. This fast procedure employed materials and techniques selected in part for speed, but also those that would not contribute unwanted artifacts. The use of SPE allowed BPA to be extracted plus concentrated, which may result in greater method sensitivity compared to simple headspace or ...

  • H2 consumption by anaerobic non-methanogenic mixed cultures

    The impact of H2 consumption, by homoacetogens, on the overall hydrogen yield in mixed culture fermentation is the focus of this study. Batch reactors were used to test the ability of anaerobic digested sludge, heat treated to eliminate methanogens, to produce and consume molecular hydrogen. The measured average hydrogen production rate from 4.2 g glucose/L was 44 ± 4 mmol H2/L sludge · d, while ...
