  • 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 ...

  • 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 ...

  • To Automate Where no Plant has Automated Before: Acid Washing of Packed-Tower Chemical Scrubbers

    ABSTRACTThe Orange County Sanitation District (Sanitation District), under a capital improvement project, developed an automated procedure to perform acid washing on packed tower chemical scrubbers. Packed-tower chemical scrubbers operate with an alkaline solution, composed of sodium hydroxide, an oxidant, and make-up water. The make-up water may be chlorinated secondary treated wastewater or ...

  • Growing water shortages, air & water pollution challenge US to take a sustainable approach to the environment

    With 36 states expected to experience moderate to extreme water shortages by the year 2013, the time has come for the United States to rethink its approach to the treatment, storage and reuse of water on a residential, industrial, and municipal level, according to Bord na Móna Environmental Products U.S. Inc. President Shane Keaney. “The aging United States water treatment infrastructure now ...

  • Experiences diagnosing a poorly performing bioscrubber and developing solutions

    ABSTRACT The City of Escondido owns and operates the Hale Avenue Resource Recovery Facility (HARRF) located at 201 North Broadway in Escondido, California. HARRF receives and treats wastewater from residential, commercial and industrial properties in Escondido. An odor control system consisting of a bioscrubber and mist scrubbers treats 66,000 cubic feet per minute of foul air from the primary ...

  • Application Data for Dry-Scrubbing Media in Collection Systems

    Abstract Dry-scrubbing systems have been used for many years to control odors in wastewater applications. The systems have ranged in size from larger multiple bed scrubbers for force mains and large pump station applications to smaller single bed systems and modular systems in small wet wells, motor control centers, and other areas. Two reasons for their continued use are simplicity of ...

  • Longer Life For Biofilters

    Biofilters are the odor control system of choice at composting facilities. Despite similar capital costs, the biofilters are generally less costly to operate than chemical scrubbers. The key to keeping operating costs in check, however, is to get the maximum use out of the biofilter media, thus avoiding the time and money needed to do media replacements. Allen Boyette, senior engineer and manager ...
