  • 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 ...

  • Water treatment helping cars stay cool - automotive industry: Orlando, Florida

    A manufacturer of air-conditioning line connectors for automobiles was required by the city to meet new sewer discharge standards. They had been using a system of gravity separation which did not address suspended solids or soluble metals. Their wastewater is generated from 3 sources; mop water, parts deburring and polishing, and floor scrubber water. They generate approximately 6,000 gpd of ...

  • Ultraviolet Light Oxidation of Free-Chlorine in Water

    Chlorine is the most frequently used chemical for water disinfection. Many industrial and commercial manufacturing facilities cannot tolerate the introduction of chlorine into the process because of contamination and unwanted chemical reactions. Chlorine affects the flavour and odour of drinks and fluids, accelerates corrosion on process vessels and piping, and can also damage delicate process ...

  • 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 ...

  • 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 ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • Chlorinated solvents: methylene chloride and TCE

    Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. Phase I began with refrigerated condensation (C3) in order to achieve high mass removal rates to reduce lifecycle costs and time ...

  • The Use Of UV For Dechlorination

    For many years chemical disinfection techniques have been used to provide microbiologically pure water for industrial and domestic use. Free chlorine, typically introduced by municipal water treatment plants in gaseous form, has been employed for many decades as a primary oxidising agent for the control of microbiological growth. Free chlorine can also be introduced through the injection of ...
