    Air pollution control (APC) equipments for pharmaceutical industry

    The pharmaceutical industry worldwide is facing a major challenge. The productions of desired chemicals leaves an amount of by-products, some of them dangerous to both humans and the environment. An incinerator is usually used to deal with the challenge to reduce the volumes of hazardous substances. This process, however, creates sub-micron particles that conventional filter technology cannot handle. By using EnviBAT’s technology for gas cleaning – the best in the industry – such issues can be greatly reduced.

    Air pollution control (APC) equipments for metal industry

    In the production of metals from ore or recycled products there are many processes where pollutants form. Smelters require high amount of energy and depending on the source of this energy and where production takes place, energy consumption can also contribute to the amount of pollution in your flue gas. In processes for metals, the metal should be purified from unwanted materials. It is inevitable that these materials as well as small amounts of the metals end up in the flue gas. Our technology is unique in its approach. It does not matter if your pollution is particulate matter, even if they are the smallest possible fraction of PM2.5, or if they are aerosols. Our patented technology handles them all. Because of the cost of production disruptions, the reliability and the high availability of our solutions provide benefits that further enhance the benefits of our technology solutions.

  • Independent particle characterization services for environmental industries

    Particle size, particle concentration and other physical characterization analyses are critical to many environmental applications. Regulatory agencies in the environmental sphere demand strict compliance to standards and discharge regulations. Physical testing of samples for parameters such as particle size and concentration can give insight to the process control engineer on how effective and compliant a discharge handling system is operating. Particulate loading from both air emissions and waste water discharge are monitored in many industry sectors and PTL testing provides valuable supporting data in this monitoring process.

  • 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.

  • Grinding & Deburring

    Grinding & Deburring dusts are Unbreathable. Many industrial processes generate contaminants in the air in the form of dust and particles. Airborne dust and fine particulate can be hazardous to human health, and should be extracted before it reaches the worker`s breathing zone.? Typical sources of these pollutants arise from cutting, grinding using an angle grinder or die grinder, automated grinding machines, deburring work and many other abrasive processes. Robotic grinding machines generally create a large volume of particulate which can require more filtration media to handle increased dust loads. Whereas other applications such as deburring can create very fine submicron particles that require the use of a high efficiency HEPA filter to capture the fines.? Metal, composite, fiberglass and rubber dust can be extremely dangerous to inhale and can be associated with many different lung conditions and health problems. Diversitech offers a diverse range of dust collectors, extraction arms, filter cleaning machines and downdraft tables for your grinding dust filtration requirements.???

  • Sulfide Oxidation with Hydrogen Peroxide (H2O2)

    Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L. Sulfide Treatment Alternatives There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application. Treatment with Hydrogen Peroxide While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective. H2O2 may control sulfides in two ways, depending on the application: Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.
