  • Chemical Air Pollution in the Clinical Research Environment

    There has been a revolution in awareness of chemical air pollution in research laboratories. I could tell you several 'horror stories' of casual exposure to mercury vapour, benzene and chromic acid (the ultimate glassware cleaning agent) among innocent biomedical PhD students (including myself) in the 1970s. But researchers in hospitals, and other laboratories can never afford to be complacent ...

  • Legionnaires is an Air Quality Risk

    The recent Bronx, NY outbreak of Legionnaires infections is a grim reminder of the deadliness of this strain of pneumonia. Like many of the outbreaks, cooling towers caused this one. Twenty have been identified but the search is still going on. Over 120 people were infected and 12 have died. Tragically it affects the most vulnerable people–people with one or more immune system deficiencies. ...

  • Chemical wastewater treatment applying a membrane bioreactor (MBR)

    IntroductionAt the current time Membrane Bioreactors (MBR) are the primary focus of wastewater treatment technologies. MBR is a combination of biological activated sludge process for the removal of nutrients and a membrane filtration for separation of biomass and treated water. In industrial wastewater treatment MBRs have proven to be a particularly reliable technique [Cornel et al., 2006]. The ...

  • How Serious are the Issues of IAQ?

    In a recent report, UL’s scientists estimated that there are 80,000 chemicals in international commerce today, with only 3% having been fully evaluated for health impacts. The danger is exacerbated by sealing building envelopes to conserve energy and trapping some of these chemicals inside buildings. The increase in awareness of mold as a cause of human health complications has catalyzed an ...

  • Industrial Wastewater Treatment: Priority pollutant behaviour in on-site treatment systems for industrial wastewaters

    The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ‘process waters’ can include mother liquors, washing waters from the purification of products, ...

  • TB 56: Power plant in thailand uses liqui-cel® membrane contactors to remove co2 from water

    A major power plant in Thailand is using Liqui-Cel® Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel Contactors are being used to lower the CO2 inlet into an Ionpure EDI system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. ...

  • Membrane-integrated hybrid bioremediation of industrial wastewater: a continuous treatment and recycling approach

    A new membrane-integrated hybrid treatment system was investigated to turn highly hazardous coke wastewater reusable. This could protect both air and surface water bodies from toxic contaminants such as ammonia, phenol, cyanide, thiocyanate and other carcinogenic aromatic compounds which are normally released into the environment during discharge of coke wastewater and during quenching of coke ...

  • Replacement of hazardous chromium impregnating agent from silver/copper/chromium-impregnated active carbon

    Activated carbon (AC) is widely used as an effective adsorbent in many applications, including industrial-scale air purification systems and air filter systems in gas masks. In general, ACs without chemical impregnation are good adsorbents of organic vapors but poor adsorbents of lowmolecular-weight or polar gases such as chlorine, sulfur dioxide (SO2), formaldehyde, and ammonia (NH3). ...

  • 5 ways to keep asthma in check

    Asthma rates have been on the rise for some time - in 2009 nearly 1 in 12 Americans were diagnosed with the long-term inflammatory disease that restricts airways and makes it difficult to breathe.
