Mazda Limited designs and manufactures industrial air pollution control equipment for controlling and removing particulates, acid gases, fumes, and other contaminants from industrial process exhaust streams. Our portfolio includes jet venturi fume scrubbers, packed tower scrubbers, high energy fume scrubbers, and wet electrostatic precipitators (WET ESP) — engineered around each application’s gas composition, particulate size, and required removal efficiency rather than supplied as fixed configurations.
Mazda Limited has been engineering and manufacturing process equipment since 1977, with expertise spanning air pollution control, vacuum, and heat transfer technologies, and holds ISO 9001, ISO 14001, and ISO 45001 certification along with PED, IBR, ASME, and U-Stamp compliance.
Air pollution control equipment removes particulates, acid gases, and fumes from an exhaust or process gas stream before it’s released to atmosphere, helping plants meet emission compliance requirements and reduce environmental impact. Different pollutants call for different removal mechanisms – wet scrubbing uses a liquid to capture and absorb contaminants, while electrostatic precipitation uses an electric charge to capture fine particulates and mist that scrubbing alone may not fully remove.
The right technology depends on the pollutant type (particulate, gas, or both), particle size, gas flow rate, and the removal efficiency required to meet emission limits. Mazda evaluates these conditions before matching an installation to a jet venturi scrubber, packed tower scrubber, high energy scrubber, or WET ESP — often used in combination for multi-stage treatment.
Use a liquid, typically water or a chemical solution, to capture particulates and absorb gaseous pollutants from the exhaust stream.
Jet Venturi Fume Scrubbers – use high-velocity liquid injection through a venturi throat to capture particulates and absorb acid gases and fumes such as SO2, HCl, HF, NH3, and SiF4 in a single stage, with no conventional moving parts in the scrubbing section.
Packed Tower Scrubber – passes gas counter-current through a packed bed irrigated with scrubbing liquid, giving high mass-transfer efficiency for gas absorption duties involving suitable soluble gaseous contaminants such as acid gases.
High Energy Fume Scrubber – a high-pressure-drop venturi scrubber designed to capture sub-micron particulates and fumes that lower-energy scrubbers cannot effectively remove.
Captures fine particulates and acid mist using an electric charge, commonly used as a polishing stage after wet scrubbing.
WET ESP – a wet electrostatic precipitator that captures sub-micron particulates and acid mist at low pressure drop, typically used downstream of a scrubber for final-stage emission polishing.
Selection depends on the pollutant type and particle size distribution in the exhaust stream, required removal efficiency, gas flow rate, and whether the application needs gas absorption, particulate capture, or both.
| Application Requirement | Suggested Equipment |
|---|---|
| Combined particulate capture and acid gas absorption in one stage | Jet Venturi Fume Scrubber |
| High-efficiency gas absorption for suitable soluble contaminants with relatively low particulate loading | Packed Tower Scrubber |
| Fine or sub-micron particulate and fume capture | High Energy Fume Scrubber |
| Final-stage polishing of sub-micron particulates and acid mist | WET ESP |
Mazda’s engineering team evaluates the exhaust stream’s composition and the plant’s emission targets before recommending a configuration – often a combination of stages – rather than offering a fixed, off-the-shelf system.
captures solid and liquid particulates from process exhaust before discharge to atmosphere
absorbs acid gases such as SO2, HCl, and HF from exhaust streams
captures fine fumes and aerosol mist that standard scrubbing may not fully remove
supports industrial processes in achieving applicable particulate and gas emission requirements
treats selected odor-producing gases where the contaminants are suitable for wet scrubbing
appropriately designed wet scrubbing systems can treat gas streams at elevated temperatures, subject to process-specific design
Mazda’s air pollution control equipment can support applications across:
Mazda’s Air Pollution Control Division engineers scrubbing and precipitation systems around each plant’s specific exhaust composition and emission targets, backed by ISO 9001, ISO 14001, and ISO 45001 certification, PED compliance, and IBR, ASME, and U-Stamp accreditation across the company. Customers get in-house engineering and after-sales technical assistance for both domestic and export projects.
A fume scrubber removes particulates and absorbs gaseous pollutants from an exhaust stream by contacting the gas with a liquid, helping plants meet emission compliance requirements before discharge to atmosphere.
Common industrial air pollution control technologies include venturi scrubbers, packed tower scrubbers, high-energy scrubbers, and wet electrostatic precipitators. The appropriate technology depends on the type and concentration of pollutants, gas flow rate, particle size, operating conditions, and required removal efficiency.
A jet venturi scrubber uses high-velocity liquid injection through a venturi throat to capture particulates and absorb gases such as SO2, HCl, HF, NH3, and SiF4 in a single, compact stage, suited to combined particulate and gas removal. A packed tower scrubber passes gas counter-current through a liquid-irrigated packed bed, giving higher mass-transfer efficiency for gas absorption but is less suited to high particulate loads due to fouling risk.
A high energy fume scrubber uses a high-pressure-drop venturi design to capture fine or sub-micron particulates and fumes that standard, lower-energy scrubbers cannot effectively remove.
A WET ESP (wet electrostatic precipitator) uses an electric charge to capture fine particulates and acid mist from an exhaust stream at low pressure drop, commonly installed downstream of a scrubber as a final polishing stage.
Selection depends on the pollutant type (particulate, gas, or both), particle size distribution, gas flow rate, and the removal efficiency required to meet emission limits. Mazda's engineering team evaluates these factors before recommending a configuration, which may combine multiple stages.
Yes. Mazda's scrubbers and WET ESP systems are engineered to each plant's exhaust composition, flow rate, and emission targets, including retrofits and multi-stage system integration.
Both. Mazda supplies complete multi-stage air pollution control systems as well as individual scrubbers and WET ESP units for existing installations.
Yes. Scrubbing and precipitation technologies are often used in sequence where a process generates multiple contaminant types or a range of particle sizes — for example, a venturi or packed tower scrubber for bulk particulate and gas removal, followed by a WET ESP for fine particulate and mist polishing. The appropriate combination depends on the specific gas stream and required removal performance.
