  • Using Biological Filtration to Remove Arsenic from Drinking Water

    In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...

  • Vapor Intrusion Issues Risk Occupants’ Health

    Vapor intrusion occurs when a gaseous substance migrates into a building.  For example, volatile organic compounds and other gases can migrate from contaminated soils and groundwater through cracks in foundations or sewer lines and enter a building.  Vapor intrusion can create an indoor environment that damages structural materials and puts building occupants’ health at ...

  • Air uality in IVF Labs

    Since the birth of the first baby from in-vitro fertilisation (IVF) in 1978, Assisted Reproductive Technology (ART) has grown in importance as techniques and success rates have continued to improve. Put simply, IVF involves mixing sperm and egg in a lab to create an embryo which is then replaced in a woman's womb to develop normally with success being measured in terms ...

  • Case study - Paint spray

    Problem A major automotive component supplier needed to control the emissions from its paint spray process. The plant emissions had characteristics common to many paint spray plants: high air flow, low volatile organic compound (VOC) concentration and particulate. The company needed an emission control solution that had low operating costs and that could also fit in their limited space. ...

  • Indoor air quality can be improved by employing plants as walls

    The practice of planting ivy to climb up the walls of buildings has existed for centuries. Now, the trend towards sustainability and green building practices can lead to the development and use of living walls as a means of filtering and improving a building’s indoor air quality. Green walls are a living, breathing, regenerating type of cladding that can be as simple as a living art installation ...

  • Case study - Deodorization at waste water treatment plants

    The presence of microorganisms in wastewater causes a decrease in dissolved oxygen levels due consumption by the organisms’ metabolic processes. The more microorganisms there are, the greater the biological demand for oxygen. When this demand exceeds that which can be provided by the exchange of air, an anaerobic process begins, thus creating a reducing environment that favours the ...

  • Project profile - Blue Rhino Hamptonville, NC

    Background In 2007, Blue Rhino, located in Hamptonville, NC, contacted AdEdge Technologies, Inc. (AdEdge) to install an iron and manganese treatment system. The amount of iron (5.6 mg/L Fe) and manganese (0.6 mg/L Mn) were well above the maximum contaminant levels of 0.3 mg/L Fe an 0.05 mg/L Mn respectively. The pH of the Blue Rhino site (6.10) was quite below the maximum contaminant ...

  • What is the size distribution and sources of particles in ambient air?

    The particle sizes in the ambient air are ranged from 1 nanometer to slightly more than 10 micrometers. There are three modes: coarse, fine and nano. The course mode particles are road dusts, spores and pollens. The minimum sizes of these particles are 1 to 3 micrometers. The fine mode particles are generally secondary particles formed from reactions such as smoke, sulfates, nitrates, ammonium ...

  • Solutions for Safe Drinking Water Through Biological Water Treatments

    Most people across the U.S. expect to turn on their faucets and have immediate access to clean drinking water. The truth is, it wasn’t until 1974 that Congress passed the Safe Water Drinking Act with the goal of regulating the nation’s public water supply. Over the years, the SWDA has been amended to include water sources as well, such as rivers, lakes, springs and groundwater wells ...
