  • 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 ...

  • Biotreatment of Odors from the Zimpro Sludge Conditioning Process

    Management of odor emissions generated during thermal sludge conditioning is a well known disadvantage of the “Zimpro” process. Traditional methods of using chemical oxidation and high temperature destruction result in the formation of secondary products, such as chlorine gas, organic halocarbons or nitrogen oxides. In this study, biotrickling filter technology was evaluated at the Villa Hills ...

  • 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 ...

  • Controlling Odors from Waste Water Treatment Plants

    INTRODUCTION In recent years, there is growing public awareness of odors from waste water treatment plants, which mainly stems from the following observed trends: The public is less tolerant of objectionable odors from waste water treatment plants; Many waste water treatment plants have seen residential, commercial, or other developments established near the facility ...

  • Effects of Anaerobic Digester Sludge Age on Odors from Dewatered Biosolids

    Dewatered sludge cakes from bench scale anaerobic digesters operated at mesophilic temperatures and solids retention times (SRT) ranging from 10 days to 40 days were evaluated for their sulfur odor generation potential. Extracellular Polymeric Substances (EPS) extraction for digested sludge samples was also carried out. Static headspace sulfur gas analysis was successfully used to compare ...

  • Case study - Stainless steel RTOs for ethanol emissions and odors

    Overview A 42 million gallon expansion at an ethanol production plant in Nebraska was certain to put the dry mill out of emission compliance for Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs), carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM), all regulated by the EPA. Ethanol production facilities in the United States are permitted to operate ...

  • Bio-Solids Process Enhancements Resulting From the Use of Hydrogen Peroxide for Hydrogen Sulfide Odor Control - The San Antonio Experience

    ABSTRACTThe paper will present results of a trial initiated in February 2004 by the San Antonio Water System (SAWS) to quantify the impacts of hydrogen peroxide injection prior to dissolved air flotation thickening of wastewater sludges. Since February 2000, the San Antonio Water System has successfully used iron salts (FeSO4) for odor and ...

  • The effect of iron and aluminium for phosphorus removal on anaerobic digestion and organic sulfur generation

    The addition of iron or aluminium into activated sludge basins for phosphorus removal is likely to impact both the efficiency of the anaerobic digestion process and the generation of odor-causing compounds following digestion and dewatering. In this study, the impact of iron and aluminium addition on digestion and odor-causing compounds was investigated by using batch digestion of combined ...

  • Understanding biogenic sulfide corrosion

    It is widely understood that wastewater collection and treatment systems are a source of malodorous odors. The most prevalent odorous gas is hydrogen sulfide (H2S), a toxic and corrosive gas with a characteristic rotten egg odor. What may often be overlooked, however, is that fact that H2S is also a precursor to the formation of sulfuric acid, H2SO4, which causes the destruction of metal and ...

  • Effects of UVGI filtration on indoor air contaminants and HVAC systems

    Proprietary High Intensity UVC (Germicidal 254 nm) Mercury Vapor Quartz Lamps designed to prevent and destroy mold and other microbial growth on the A/C coil and eliminate biological contaminants and chemicals in the air. Ultraviolet light destroy biological & chemical contaminants TOMIES proprietary High-Intensity Mercury Vapor Quartz Lamps produce UVC and UVV (both ...

  • Effect of Secondary Aerobic Digestion on Properties of Anaerobic Digested Biosolids

    ABSTRACTIn this study, the performance of sequential anaerobic-aerobic digestion was compared to conventional anaerobic digestion for sludge from the Blue Plains Advanced Wastewater Treatment Plant. Volatile solids removal, polymer conditioning demand for dewatering, and biosolids odor characteristics following anaerobic digestion and sequential anaerobic-aerobic digestion were monitored. Aerobic ...

  • Humid, corrosive and malodorous waste gases - Case Study

    Example: Production of bio-ethanol Similar tasks: Dryers, Fibre board industry The production of bio-ethanol - fermentation, distillation, pelleting and drying - generates odorous and humid waste gas. Upstream lamellar demisters reduce both drop formation - causing lower VOC destruction efficiency - and solid matters. The regenerative thermal oxidiser (RTO) ...

  • Ultrasonic Waste and Sludge Treatment

    Biogas is generated from sources, such as municipal organic waste, sewage sludge, muck or manure. Ultrasonication improves the digestibility of such organic material leading to more biogas and less residual sludge. Biogas is a byproduct of the decomposition of organic matter by anaerobic or aerobic bacteria. It consists primarily of methane, carbon dioxide and hydrogen sulfide. This makes biogas ...

  • The Effect of the Microsludgetm Treatment Process on Anaerobic Digestion Performance

    ABSTRACT Thickened waste activated sludge (TWAS) from biological treatment processes is less amenable to anaerobic digestion than primary sludge. This is due to TWAS being composed mostly of cellular material and extracellular polymeric substances (EPS) instead of more easily digestible carbohydrates and fats that are typically found in primary sludge. In an attempt to improve TWAS digestion ...

  • Case study - Catalytic oxidizer catalyst replacement

    Overview A New Jersey pharmaceutical company purchased a thermal incinerator to treat the heptane and hexane exhaust from their capsule wash system. The thermal incinerator"s "tubular" design was modified with a catalyst bed in order to reduce the system"s operational costs. Unfortunately, when operating in the catalytic mode, the oxidizer failed to provide the required ...
