  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • Gas Hydrate Breakdown Unlikely to Cause Massive Greenhouse Gas Release

    The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester. Methane hydrate, which is also referred to as ...

  • Activated Carbons and Manufactured Gas Plants

    The purpose of this paper is to discuss the pros and cons related to each of these factors when using one of three accepted options in conjunction with the "hog and haul" method of remediating a site. The options are the use of (1) minimal controls, (2) extensive onsite monitoring and (3) a fabric structure with limited air testing. As we are all aware, the government continues to react to ...

  • Characterization of air plasma-activated carbon nanotube electrodes for the removal of lead ion

    Carbon nanotube electrodes were prepared by pressing a mixture of carbon nanotubes and polytetrafluoroethylene (which acted as a binder) on a stainless steel net collector, and the electrodes were subsequently activated in our self-designed plasma apparatus, using air plasma. The morphology and surface functional groups of the electrodes were characterized using scanning electron microscopy and ...

  • Application of air stripping to powdered activated carbon adsorption of geosmin and 2-methylisoborneol

    Removal of odor-causing compounds (OCCs) including geosmin and 2-methylisoborneol (2-MIB), well known to cause the musty and earthy odor in drinking water, was investigated using powdered activated carbon (PAC) adsorption and air stripping processes. Removal by air stripping was mainly affected by aeration flow rates with volumetric mass-transfer rates of 0.002–0.005 min−1. Aeration also proved ...

  • The Dangers of Hydrogen Sulfide and Filtration with Activated Carbon

    Hydrogen sulfide (H2S) is a poisonous, highly flammable, colorless gas that is associated with a ‘rotten egg’ odor. As stated by cchealth.org, “hydrogen sulfide is created naturally by decaying organic matter and is released from sewage sludge, liquid manure, and sulfur hot springs.” It also is a by-product from industrial processes such as natural gas processing, ...
