  • Wastewater and groundwater

    Nearly 25 percent of the population in the United States—in more than 25 million homes—disposes of wastewater through onsite, or unsewered, systems that return treated effluent to the ground. This is an important public health issue because many of those same homes use wells that rely on groundwater for the drinking water supply. With ...

  • Controlling Fugitive Emissions, Part 1: Close Capture Hooding

    Fugitive emissions, in their simplest form, are the uncontrolled release of gases to the atmosphere. Each one of us may contribute fugitive emissions when we fill our automobile gas tanks. The displacement of air inside the gas tank causes gasoline vapor emissions (hydrocarbons) to exit out the fill spout (un-controlled) to ...

  • Unpleasant Odors Successfully Removed Using Biological Waste Water Treatment

  • Odor removal by powdered activated carbon (PAC) in low turbidity drinking water

    The potential of powdered activated carbon (PAC) adsorption for odor removal in low turbidity drinking water was investigated. The batch experiments were conducted under various conditions including PAC species, dosage, contact time and dosing point. The effects of pre-chlorination and PAC dosage on turbidity were also studied. Results showed that adsorption was quite vulnerable to initial ...

  • 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, ...

  • Hydroxyl-Radical Odor Control

    In-Pipe now offers the IPTC(OH-), a hydroxyl radical based odor control option for Lift Stations and WWTP headworks that requires no chemicals, needs only a small footprint and uses minimal electrical power. The IPTC(OH-) chemical free scrubber system connects to the existing lift station vent to oxidize hydrogen sulfide outside of the lift station environment in order to scrub odors before ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • Are membranes the answer to odor?

    ABSTRACT A microporous hollow fibre membrane operating in non-wetted mode has been applied to the removal of hydrogen sulphide from gas streams. The case studies under investigation were (i) H2S absorption within single passage through the membrane and (ii) H2S absorption with recycle. Counter-current flow configuration was considered with the test contaminant passing through the shell-side of ...

  • Mercaptan odor control - case study

    Background In municipal and industrial waste treatment, hydrogen sulfide is not the only offensive gas generated from anaerobic decomposition. Mercaptans (RSH) are the organic equivalent to hydrogen sulfide and more odorous at 1/1000th the concentration. Mercaptans are naturally occurring from the degradation of sulfur containing organics (proteins, etc.).   A table of ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...

  • An odor predictive model for Rendering applications

    Abstract The rendering process consists of crushing and heating animal remains to produce by-products. The U.S. produces approximately 30 billion pounds of inedible animal by-products annually, exporting a market value of US$ 1.5 billion. Benefits of the rendering process include reducing total waste material, and helping the livestock industry stay competitive over vegetable protein ...

  • Compact scrubber for biosolids odors saves $500,000

    A new scrubber at a Camden, NJ bio solids processing facility uses advanced technology to cut the cost of odor control. The system was designed, built and installed by Bay Products with process design assistance from Lantec Products. A single tower is used to remove malodorous gases from air in two stages having separate sumps for the recirculated scrubbing solutions. The lower stage absorbs ...
