  • 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 ...

  • Managing Ponds for BOD Reduction and Odor Control

    A large number of food processors utilize ponds to treat their wastewater. Most of the time these ponds are aerobic in which they use oxygen to degrade the wastewater biological oxygen demand (BOD). Fruit and vegetables contain a high amount of simple sugars and other organic compounds that when exposed to water are released into the water stream. These organic compounds require oxygen to degrade ...

  • The effect of direct addition of iron(III) on anaerobic digestion efficiency and odor causing compounds

    The role of iron addition to sewage sludge prior to anaerobic digestion was evaluated to determine the effect of iron on digestion performance and generation of odor-causing compounds. Hydrogen sulfide (H2S) and volatile organic sulfur compounds (VOSCs) were the odorous gases evaluated in this study. Samples were obtained from seven municipal wastewater treatment plants (WWTPs), and batch ...

  • 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 ...

  • Control of biosolids cake odors using the new biosolids odor reduction selector process

    ABSTRACT Recent introduction of more efficient dewatering devices that generate higher solids concentrations in dewatered cake has been plagued with the non-desirable side effect of more odorous dewatered biosolids. Previous research has shown that the production of volatile organic sulfur compounds (VOSC’s) such as methanethiol (MT), dimethyl sulfide (DMS), and dimethyl disulfide (DMDS) ...

  • Case study - Asphalt plant odor control in North Carolina

  • Using UV for Simultaneous Disinfection and Control of Unpleasant Tastes and Odors in Drinking Water

    Algae blooms in surface water sources often lead to off-tastes and odors in finished drinking water. Because public confidence in overall drinking water quality is closely related to aesthetic quality, there is increasing interest in solving taste and odor issues.  UV-oxidation, the combination of UV and hydrogen peroxide, offers the ability to treat taste and odor (T&O) while simultaneously ...

  • Data Based Management of an Odor Control Program – A Case History in Program Improvement
