  • What is Activated Carbon?

    Adsorption with activated carbon can apply. The more awareness people have of the Earth, the more applications activated carbons will have. is thus a commonly seen process in applications such as gas masks, space capsules, nuclear plants and so forth, in which the removal of gases is highly needed. ...

  • The Phase 1 Environmental Assessment

    In today’s world where every property is subject to potential environmental risks a Phase 1 Environmental Site Assessment or ESA is an appropriate action to take. An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property.  Lenders ...

  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Odour Control at Pesticide Facilities: Eliminating volatile compounds

    Chemical formulation plants are susceptible to emissions of unpleasant and malodorous volatile compounds, a fact which makes the implementation of efficient odour control measures essential. North-western Spain is home to one of the country's oldest industrial sites for the manufacture of phytosanitary products, with some facilities located relatively close to populated areas. Recently, the ...

  • Following the fuel: How portable biomass energy generation may help rural communities

    The forests that surround many of California’s mountain communities tend to have an abundance of woody biomass and a pressing need for thinning to reduce fire danger. Revenue from selling forest residues to biomass power plants could help to support fuel reduction activities, but in many cases the nearest plant is so far away that hauling costs are prohibitive. The remoteness of such ...

  • 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 ...

  • Overheating Damage at Activated Carbon Filter

    At one of the DMT’s plants recently a safety incident occurred. An Activated Carbon Filter overheated due to an incorrect mode of operation, causing damage to the installation. This led to a significant financial loss including business interruption impacts. To raise awareness for correct operation of Activated Carbon Filters, DMT publishes this S.H.E. bulletin to prevent this from ...

  • Top 3 Uses of Activated Carbon

    Activated carbon is an effective purifier. It is used to remove organic pollutants from different gaseous, liquid and solid substances. By removing the undesirable organic compounds, activated carbon can successfully remove the odour and taste of these compounds from a wide range of things.  Unlike other purification agents that react with organic compounds and change their nature, activated ...

  • 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, ...

  • Activated Carbon Applications Excel at PCB Removal

    TIGG’s GAC adsorption equipment is used to remove PCBs from groundwater. For more than 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban of ...

  • Capturing Organic Vapors from Non-Condensable Gases Using Activated Carbon Adsorption Technology

     There are many established uses of vapor phase carbon adsorption technology in the chemical industry. The majority are to capture organic vapors from non-condensable gas streams, such as process exhausts. Other applications include process gas separations such as the removal of oxygen from air in the production of nitrogen. This article focuses on the capture of organic vapors from ...

  • 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). ...

  • Worldwide Activated Carbon Market is expected to grow at a CAGR of 13.3% from 2014 to 2020: Grand View Research, Inc

    The global market for activated carbon is expected to reach USD 5,305.0 million by 2020, according to a new study by Grand View Research, Inc.
