  • 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 ...

  • 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 ...

  • 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 ...

  • The use of potassium permanganate, ozone and associated coupled processes for odor removal in drinking water: bench and pilot scale tests

    Bench and pilot scale experiments were conducted to investigate and compare the preoxidation effects of potassium permanganate (KMnO4) and ozone (O3) for odor removal in drinking water. The effects of dosage, contact time, pH, as well as couple treatment with a granular activated carbon (GAC) filter were examined using bench experiments, while the effects of KMnO4 dosing ...

  • Case Study: Odor Abatement Solutions

    Odor issues related to industrial processes are not uncommon.  An odor is caused by one or more volatilized organic compounds (VOCs) that humans can perceive by the sense of smell.  The challenge is that “odor is subjective, and what is sweet to some, can be a nuisance to others.   In most cases the ...

  • Optimization of Fenton's reagent coupled to Dissolved Air Flotation to remove cyanobacterial odorous metabolites and suspended solids from raw surface water

    Ferrous salts are commonly used as coagulants in Water Treatment Plants (WTPs). When these salts are combined with hydrogen peroxide in acidic conditions – besides coagulation – an additional Advanced Oxidation Process (Fenton's reagent) can take place. Using a response surface methodology, this paper presents the optimization of a novel treatment system constituted by Fenton's reagent (FE) and ...

  • Odorant screening and possible origin analysis of odor episodes in one reservoir in northern China

    Odorous drinking water problem occurred repeatedly in one city in northern China in recent years. The uniqueness of this odor episode lay in two aspects: (1) the odorous chemicals were quite different from common odorants, such as geosmin and 2-MIB; and (2) it occurred repeatedly in different seasons during a time span of more than 2 years. The screening of odorants was the first and one of ...

  • 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 ...

  • Case study - Meat processing odor control

    Overview For its first two years of production, a food manufacturer based in South Wales, England, focused its production on potatoes. Neighborhood residents voiced no complaints about odors during this time period. However, as new production lines (including barbequed meats and curried chicken) were added, the complaints began, and it became clear that odor abatement equipment was needed ...

  • Odor Control at Biodiesel Plant - Case study
