  • Behaviour and adsorptive removal of siloxanes in sewage sludge biogas

    We investigated the behaviour of siloxanes, which adversely affect biogas engines, as well as their concentration levels in sewage sludge biogas in Japan. We also performed experiments on the absorptive removal of siloxanes using various adsorbents and determined the main adsorbent characteristics required for the removal of siloxanes. The results of our study on the concentration and composition ...

  • Tissue‐based risk assessment of cyclic volatile methyl siloxanes

    Cyclic volatile methyl siloxanes (cVMS) are important consumer materials that are used in personal care products and industrial applications. These compounds have gained increased attention in recent years following the implementation of chemical legislation programs worldwide. Industry‐wide research programs are being conducted to characterize the persistence, bioaccumulation, and toxicity (PBT) ...

  • Development of a low‐density polyethylene‐containing passive sampler for measuring dissolved hydrophobic organic compounds in open waters

    A passive water sampler with low‐density polyethylene (LDPE) as the sorbent phase was built and field‐tested for sensing freely dissolved concentrations of hydrophobic organic compounds (HOCs) in fresh and coastal water. Based on the measured LDPE–water partition coefficients (Kpew) of 12 polycyclic aromatic hydrocarbons (PAHs) and dichlorodiphenyltrichloroethane (DDT) and its seven metabolites, ...

  • Case study - Purification of biogas in EDAR Mapocho

    BIOCONSERVACION: Integral solution for biogas purification in WWTPs Biogas is mainly composed by methane and carbon dioxide as a result of organic matter fermentation in the absence of air by the action of a microbial consortium (anaerobic digestion). The composition of biogas depends entirely on the nature of the waste processed and the conditions under which takes place the anaerobic digestion. ...

  • Synthesis and characterisation of nano silica-based coatings for protection of antique articles

    Antique articles are endangered by environmental effects such as humidity, UV and variation of temperature. Improved physical surface resistance is in an increasing demand in protection of cultural heritage. One possible way is their protection by suitable hydrophobic coatings. In this work, the experimentation of protective treatments on the soda glass, mud brick and copper, characteristic ...

  • Contact Lens Permeation Testing from Systech Illinois

    A contact lens design using a particular material will require the measurement of Oxygen Permeation.  Materials with higher permeation rates together with thinner lenses will perform better, providing greater comfort during use.  However, simply choosing the material with the highest permeation rate and making the lens thin is not an easy option.  The lens shape and thickness ...

  • Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

    To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...
