  • Clearing the air: the use of bio-oxidation for industrial air emissions control

    The wood products industry began rather ardous road to emissions control in the early 1990s with the first installation of a thermal oxidizer (an RTO) at a California MDF facility, for volatile organic compound (VOC) control. During the ensuing years, virtually every panel board facility has had to control emissions of VOCs, and up until the last few years, always with some sort of thermal ...


  • The next generation biological odour control systems

    Odour is usually caused by the presence of hydrogen sulphide, mercaptans (Organic sulphur components) and ammonia, but also multiple other VOC’s (volatile organic compounds) bringing numerous odour complaints at e.g. WWTP’s, pumping stations and composting plants. An odour control system therefore will have to treat not only hydrogen sulphide, but also other pollutants to reduce the total ...

  • Air Emissions from the automobile manufacturing industry: a bio-oxidation pilot study of paint emissions control

    Bio•Reaction Industries (BRI) was contacted by Toyota to assess the abatement potential of an engineered bio-oxidation system (biofilter). The proposed intent of the pilot was to evaluate the effectiveness of biofiltration as available alternative to traditional VOC removal technology on an existing 3 stage wheel paint booth. A pilot unit consisting of a biotrickling filter and a separate ...

  • Modeling of air stripping from volatile organic compounds in biological treatment processes

    The removal of volatile organic compounds from biological treatment processes occurs through several mechanisms. These include biodegradation, adsorption onto solids, and air stripping or volatilization to the atmosphere. Volatilization results in fugitive emissions to the atmosphere, which is largely uncontrolled. Recent regulations have called ...

  • Biofiltration - A Disruptive Technology for Sustainable Air Pollution Control

    ABSTRACTAir Pollution Control has emerged over the past 40 years as a significant industrial sector helping industrial facilities reduce emissions to comply with environmental regulations, reduce costs, and improve their public image. A variety of technologies have been developed to meet the needs of both the industries and the regulatory agencies.  Engineered biofiltration is a sustainable ...


  • The Whole Plant Approach to Air Emission Modeling for NESHAP Compliance

    ABSTRACTLong overlooked, the air emissions associated with biological treatment of process wastewaters continue to be further scrutinized and regulated. The common approach is to utilize EPA’s Water9 as a model to present findings and support permitting activities. It is essential when using a model that not only is the facility modeled appropriately, but also that the specific compound ...

  • 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, ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Control of Aerosol Contaminants in Indoor Air: Combining the Particle Concentration Reduction with Microbial Inactivation

    ABSTRACT An indoor air purification technique, which combines unipolar ion emission and photocatalytic oxidation (promoted by a specially designed RCI cell), was investigated in two test chambers, 2.75 m3 and 24.3 m3, using nonbiological and biological challenge aerosols. The reduction in particle concentration was measured size selectively in realtime, and the Air Cleaning Factor and the Clean ...

  • Shipping Emissions - The Environmental Case for Sea Water Scrubbing

    The romantic image of a luxury liner cruising blue seas amid blue skies and trailing a plume of smoke is too close to the truth for comfort. The emissions from shipping make an increasingly conspicuous contribution to air quality, health and environmental problems of Europe, and indeed, the world. Yet an effective and safe technology to dramatically reduce these emissions is being discouraged, ...


  • 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 ...

  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • 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 ...

  • 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 ...

  • Hydrogen Sulfide control in a municipal sewer collection system case study

    Odor and Corrosion Control in Pump Stations Using Microcat – ANL BioBlend – BSE 104 Problem Hydrogen sulfide generated in sewer systems can cause safety and maintenance problems including toxicity to humans, odors and corrosion. Several methods are used to control hydrogen sulfide in collection systems. While many have proven to be at least partially ...

  • Removal of methyl tertiary butyl ether (mtbe) vapour from contaminated air streams using different bacterial cultures in biotrickling filters.

    Methyl tertiary butyl ether (MTBE) was firstly introduced in the Islamic Republic of Iran in the end of 2001 as gasoline octane enhancer. Ordinary, reformulated gasoline contains 11-15% (v/v) of MTBE. Because of its low production cost and excellent blending characteristics, its production has been grown exponentially in the world, reaching a value of over 33 million tons per year (Fortin and ...

  • Biotreatment of Organic and Inorganic Odors

    Air emissions from manufacturing operations and waste treatment plants often consist of a combination of odors and volatile chemicals. Odors are inorganic or organic compounds, which are present in low concentrations, typically 20 ppmv or less, which have an unpleasant odor. Volatile chemicals are often present at higher concentrations than odors, but may or may not have any odors associated with ...
