  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • Common Treatment Technologies for Nonhalogenated VOCs in Air Emissions/Off-Gases

    Three technologies that are most commonly used to treat nonhalogenated VOCs in air emissions/off-gases are carbon adsorption, catalytic oxidation, and thermal oxidation. Carbon adsorption is a remediation technology in which pollutants are removed from air by physical adsorption onto the carbon grain. Carbon is 'activated' for this purpose by processing the carbon to create porous particles with ...

  • Biofilter Removal of VOCs and Toxics from Airborne Emissions

    Abstract Sewage treatment plants can emit significant quantities of volatile organic compounds (VOCs) and toxic air contaminants, but emission control by conventional methods has been difficult to achieve. The biofilter technology developed in a previous contract can satisfactorily control emissions from these plants and possibly from other sources of high-volume, low-concentration emissions ...


  • Stack gas VOC monitoring

    POLLUTION S.r.l. manufactures POLARIS FID analyzer, a cutting-edge technology for the measurement of total hydrocarbons in ambient air and stack emission monitoring in accordance with EN 13526 and EN 12619. This analyser is based on Flame Ionization Detection (FID), a reference method technique to measure total hydrocarbons (THC, VOC, TOC). Polaris FID is a very handy instrument because it allows ...

  • An assessment of urban VOC emissions and concentrations by comparing model results and measurements

    From September 1994 to June 1996, the city of Antwerp carried out a volatile organic compound (VOC) measurement campaign in the urban agglomeration of Antwerp. The results were used to further validate a traffic emission model for the city of Antwerp and to evaluate the performance of three different "street canyon" models that were applied to calculate benzene concentrations at ten ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...

  • Air Emissions/Off-Gas Treatment

    A number of technologies have been widely applied for removal of VOCs from off-gas streams. However, the application of these technologies to off-gases from site remediation may be quite limited. Biofiltration has been widely applied for VOC destruction in Europe and Japan, but it has only recently been used in the United States. Catalytic and thermal oxidation are widely used for the destruction ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • Relation between ozone levels and NOx and VOC emissions in the Sao Paulo Metropolitan Area for an episode of August, 1998

    At present, major efforts in air pollution control for urban areas are oriented to reduce ozone levels to below standards. Models are a useful tool for air quality assessment and they can help to select the best strategy plan to reduce ozone levels in a polluted area. Like other large cities in the world, Sao Paulo Metropolitan Area (SPMA) has registered high levels of ozone and particulate ...

  • Controlling Hazardous Air Emissions With A Catalytic Oxidizer

    As the full effect of the Federal Clean Air Act (CAA) Amendments continue to impact today’s industry, many companies will be required to install new or additional air pollution control equipment. With well over twenty years of proven success, catalytic oxidation is a popular method for controlling volatile organic compound (VOC) emissions.During the past 25 years, industry has made progress in ...

  • New NSPS OOOOa Regulations Affecting Methane and VOC Emissions from the O&G Sector Finalized as of June 3, 2016

     The EPA has issued three final rules that will curb emissions of methane, smog-forming volatile organic compounds (VOCs) and toxic air pollutants such as benzene from new, reconstructed and modified oil and gas sources, while providing greater certainty about Clean Air Act permitting requirements for the industry. The EPA’s amended and new regulations affecting methane (CH4) and VOC ...

  • Can Composting BMPS Reduce Air Emissions?

    Imagine a scenario where all yard trimmings collected for recycling have to be received, processed and composted under the cover of a building. It would be tough for most yard trimmings composting facilities to survive the expense. Yet this situation could have occurred in Southern California. At one point, the South Coast ...

  • Control of VOC emissions from a flexographic printing facility using an industrial biotrickling filter

    The study of an industrial unit of biotrickling filter for the treatment of the exhaust gases of a flexographic facility was investigated over a 2-year period with the objective to meet the volatile organic compound (VOC) regulatory emission limits. Increasing the water flow rate from 2 to 40 m3 h−1 improved the performance of the process, meeting the VOC regulation when 40 m3 h−1 were used. An ...
