  • Wet Dust Collectors: Options and Operations

    Wet Dust Collectors: Options and Operations

    A wet dust collector comes in the choice of three variations and these are: gas/liquid contact, gas/liquid separation and gas humidification. The difference between the three is based on how the dust is collected and separated inside the system. A wet dust collector, also known as a wet scrubber, ...

  • An Update on the Columbus Wet Weather Management Plan

    An Update on the Columbus Wet Weather Management Plan

    ABSTRACTUndergoing a system wide program for a metropolitan area of over 1 million people to address SSOs is a challenge. The same can be said for addressing CSOs throughout a system. Columbus is addressing both at once, creating a particularly daunting challenge. Columbus submitted one large report, the Wet Weather Management Plan (WWMP), to the Ohio EPA on July 1, ...

  • Keep your air clean with Wet Dust Collectors

    Keep your air clean with Wet Dust Collectors

    Wet dust collectors use liquid — often but not always simple water — to capture and separate dust, mist, fumes, and other particulate matter from a stream of flowing gas — often but not always simple air. Some wet dust collectors spray liquid in a sheet across the stream of gas; others bubble the gas through ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • Catalytic wet hydrogen peroxide oxidation of a petrochemical wastewater

    Catalytic wet hydrogen peroxide oxidation of a petrochemical wastewater

    Continuous Catalytic Wet Hydrogen Peroxide Oxidation (CWHPO) for the treatment of a petrochemical industry wastewater has been studied on a pilot plant scale process. The installation, based on a catalytic fixed bed reactor (FBR) coupled with a stirred tank reactor (STR), shows an interesting alternative for the intensification of a continuous CWHPO treatment. Agglomerated SBA-15 silica-supported ...

  • Treatment of hydraulic fracturing wastewater by wet air oxidation

    Treatment of hydraulic fracturing wastewater by wet air oxidation

    Wastewater produced by hydraulic fracturing for oil and gas production is characterized by high salinity and high chemical oxygen demand (COD). We applied a combination of flocculation and wet air oxidation technology to optimize the reduction of COD in the treatment of hydraulic fracturing wastewater. The experiments used different values of flocculant, coagulant, and oxidizing agent added to ...

  • Whirl/Wet Dust Collectors Preferred for Pharmaceutical Overspray Collection

    Whirl/Wet Dust Collectors Preferred for Pharmaceutical Overspray Collection

    A major multi-national manufacturer of pharmaceuticals and vaccines chose Whirl Wet technology for a new pill coating operation. The aqueous-based sugar solution created heavy loadings of sticky overspray in the 3 micron range. This blinded the existing baghouses after just six batches despite the use of PTFE cartridges – (the best available option for baghouses used in this type of application.) ...

  • Long-term Atmospheric Mercury Wet Deposition at Underhill, Vermont

    Long-term Atmospheric Mercury Wet Deposition at Underhill, Vermont

    Section 112(m) of the 1990 Clean Air Act Amendments, referred to as the Great Waters Program, mandated an assessment of atmospheric deposition of hazardous air pollutants (HAPs) to Lake Champlain. Mercury (Hg) was listed as a priority HAP and has continued to be a high priority for a number of national and international programs. An assessment of the magnitude and seasonal variation of ...

  • Elimination and accumulation of polycyclic aromatic hydrocarbons in urban stormwater wet detention ponds

    Elimination and accumulation of polycyclic aromatic hydrocarbons in urban stormwater wet detention ponds

    The concentrations of polycyclic aromatic hydrocarbons (PAHs) in water and sediments of seven wet detention ponds receiving urban stormwater were investigated. The ponds comprised traditional wet detention ponds with a permanent wet volume and a storage volume as well as ponds that were expanded with sand filters and other means to improve the removal of micropollutants. The concentrations of ...

  • Evaluation of wet air oxidation variables for removal of organophosphorus pesticide malathion using Box-Behnken design

    Evaluation of wet air oxidation variables for removal of organophosphorus pesticide malathion using Box-Behnken design

    This paper deals with finding optimum reaction conditions for wet air oxidation (WAO) of malathion aqueous solution, by Response Surface Methodology. Reaction conditions, which affect the removal efficiencies most during the non-catalytic WAO system, are: temperature (60–120 °C), applied pressure (20–40 bar), the pH value (3–7), and reaction time (0–120 min). Those were chosen as independent ...
