  • Food Processing: Odor Control in Edible Oil Processing

    Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen ...

  • 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 ...

  • Hydrogen Sulfide Continuous Emission Monitoring of Odor Control Systems

    ABSTRACT This paper discusses the use of the Sycamore Continuous Emissions Monitor (CEM) for monitoring Hydrogen Sulfide Gas concentrations within odor control systems. The CEM is configurable as a single, two or three point system and can measure from 5 ppb to 2 PPM, 0.1 – 20 PPM, and 0 – 200 PPM and is designed for monitoring of scrubbers, carbon adsorbers, biofilters and biotrickling ...

  • What makes an effective odor control cover system design?

    Background A common side effect of wastewater treatment processes is the unpleasant odor that can linger near the plant, annoying neighbors, who then complain. Often, the wastewater treatment plant was built many years ago in an isolated part of town.  Over the years, the town’s population grew until subdivisions were developed next to the treatment plant.   ...

  • Continuous emission monitoring and control of packed tower odor control systems using the sycamore CEM

    ABSTRACT Packed-tower chemical scrubbers, with sodium hydroxide (caustic) and sodium hypochlorite (bleach), are commonly used to treat foul air from wastewater treatment processes. The available control mechanisms include a pH probe and controller for the sodium hydroxide feed, an oxidation reduction potential (ORP) probe with a controller toestablish the bleach feed, and proprietary ...

  • Advancing Odor Control to New Levels Gurnee Sewage Treament Plant North Shore Sanitary District

    ABSTRACTThe North Shore Sanitary District (District) owns and operates a 24-mgd sewage treatment plant located in Gurnee, Illinois.
