    Odor control for composite

    A Single Solution To Manage Composite Odors: Many resins used in the composite industry emit styrene vapors which are considered hazardous in high concentrations and whose odor is an unpleasant nuisance. This gas is categorized as a volatile organic compound (VOC) and listed by the United States Environmental Protection Agency (US EPA) as a Hazardous Air Pollutant (HAP). Styrene is considered highly reactive in the atmosphere and may contribute to smog formation and the production of secondary air pollutants.

    Elimination of mercaptan odor for wastewater lagoons

    Wastewater lagoons are utilized to collect and stabilize wastewater. Approximately one third of all U.S. secondary waste treatment facilities employ some type of pond system. Lagoons can become septic, or contain compounds that product significant odors.

    Odor control for refining/petroleum

    You refine the fuel, we’ll remove the odors. Oil refineries and petrochemical plants may generate large volumes of odor from the processing and refining of different fuels. Sulfides, mercaptans, and hydrocarbon compounds are all closely related to the oil industry. The odors generated from these industrial compounds are of a high nuisance value and generally create concern among local air boards and the public. Ecosorb odor removal products may be used in a variety of areas around the refinery including water treatment facilities, sludge ponds, sulfur recovery units, and API separators. To remove odors during tank cleaning and maintenance operations, portable dispersion systems can be used in the immediate work area to control malodors. Ecosorb products can be directly injected into flues and stacks and may be used as a substitute scrubbing solution in some applications.

  • Odor control solutions for industrial sector

    Malodors can commonly be the by-prodcut of many industrial and manufacturing processes. Oil refineries and petrochemical plants may generate large volumes of odor from the processing and refining of different fuels. Sulfides, mercaptans, and hydrocarbon compounds are all closely related to the petro-chemical industry. The odors generated from these industrial compounds are of a high nuisance value and generally create concern among local air boards and the public communities which surround these plants.

    Waste water treatment plants Air quality control by TRS MEDOR Online Odor Monitoring

    ontext & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. Odors are very distinct air contaminants as they generate nuisances. The factors playing a role in the determination of odor annoyance are: odor concentration and intensity, frequency, appreciation, duration, synergy and location. CHROMATOTEC® proposes an automatic solution to well identify the origin and the level of odors.

  • Chlorine dioxide treatment for rendering

    Odor Control: Chlorine dioxide controls odors by destroying hydrogen sulfide through chemical oxidation.  Using an odor scrubber, chlorine dioxide solutions may be added directly to water containing the odorous compound for quick and cost-effective oxidations.

    Waste water treatment plants Personnel Safety & H2S filter management

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and Methylmercaptan increased. Safety of employees on such working sites has therefore become of major problem. To fight this hazardous pollution, air filtering systems have been installed. For the station managers, personal safety coupled with the need for constant air quality control and filter change has been a heavy task.

These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. To ensure the safety of operatives in the screening building/area of waste water treatment works an H2S analyzer has been installed in the main building to complement the protection provided by individual monitors. Chromatographic measurements show that other sulfurous compounds including Methylmercaptans are present in the air in addition to H2S.

  • Potable water treatment

    As a selective oxidizing agent, chlorine dioxide possesses several chemical advantages when compared to the traditional use of chlorine in wastewater treatment. Chlorine dioxide does not hydrolyze in water, and thus it retains its biocidal activity over a broader range of pH. It is also non reactive with ammonia and most nitrogen-containing compounds, and thus effective at lower dose levels than chlorine. It also eliminates phenols, simple cyanides and sulfides by oxidation. Likewise it is effective at odor control and will oxidize sulfides. Chlorine dioxide is also effective at oxidizing iron and manganese compounds.

  • Mold Control

    Controlling mold spores and bio-contaminants is a challenge for indoor gardeners that requires attention to detail and specialized equipment. An average cubic foot of air has around 100,000 mold spores. When sufficient moisture is available, mold grows. AgriAir Purifiers control and eliminate Aspergillus and many other types of spores, mildew, odors, and VOC as well as sanitize the air and hard surfaces from biological contaminants generated by organic decay during the entire growing process. AgriAir Purifiers generate ionized-hydro-peroxides, which result in a proactive method of indoor air sanitation and promote organic garden production. This purification method eliminates the need for the use of additional chemicals or biocides that generally contain toxic compounds. AgriAir products can safely be used in occupied spaces throughout the entire grow cycle all while effectively destroying mold spores and other harmful bio-contaminants.

  • Painting & Coating

    Paint fumes are Unbreathable. Spray Painting VOCs and Powder Coating dust are both harmful pollutants which are produced during painting operations. The volatile organic compounds (VOCs) emitted from paint can cause respiratory issues and require proper ventilation to remove harmful gasses from the work area. Powder Coating lines and spray painting produce dangerous fumes and dusts which need to be filtered or exhausted outside your facility. Industrial coatings and chemicals can produce toxic VOCs and foul odors which can effect worker`s health and reduce productivity. Some of the most common coatings are polymers which include polyurethane, epoxy and moisture-cure urethane. Many different industries required the use of glues, adhesives, solvents and different chemical agents in their production process, but are unsure of the best way to handle this nuisance. Exhausting fumes outside may be an option when VOCs are extremely dangerous and odorous but companies must also comply with EPA guidelines which regulate which gases can be emitted. In cold climates and in air-conditioned facilities, capturing, filtering and recirculating fumes can provide huge energy savings preventing costly heat loss and energy intensive air makeup systems. Utilizing activated carbon granules can allow operators to filter VOCs and odors from painting and cutting applications. Different quantities and types of carbon modules are required depending upon the contaminant.
