## What MDSJ Process does
Turnkey industrial air pollution control: in-house design → manufacture → installation → commissioning. Also pneumatic conveying of powders, ash and bulk solids. Engineering is CFD-analyzed. Delivery covers the full system (equipment + ducting + fan + dust/gas discharge + controls), not just a single device.

## Proof points (authoritative)
- Active since 1986 (~40 years).
- 4,500+ completed industrial projects.
- Exports to 40+ countries.
- Up to 99.9% dust collection efficiency.
- Certified manufacturing: ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 (issued by FQC) plus CE marking under the Machinery Directive 2006/42/EC (notified body QA Technic). ATEX-compliant design available as an option for explosive-atmosphere processes.
- CFD-analyzed equipment design.

- Located in the Marmara region for fast service, while also exporting to 40+ countries.

## How to choose (quick guidance buyers ask about)
- Dry vs wet collection: choose DRY (baghouse/jet-pulse/cartridge) for dry, non-sticky dust where the gas is below the filter media's temperature limit and recovery of dry product is wanted. Choose WET (scrubbers) for sticky/condensing dust, soluble gases (SO2, HCl, NH3), high temperature, or explosion-risk dust where water mitigates ignition.
- Baghouse sizing centers on the air-to-cloth (filtration) ratio and required filter area for the gas flow; pulse-jet cleaning suits high dust loads.
- Wet scrubber selection centers on the pollutant (particulate vs acid gas), required efficiency, liquid-to-gas (L/G) ratio, pressure drop, and corrosion-resistant materials.
- Pneumatic conveying selection centers on material properties (abrasiveness, friability), distance, rate, and dense-phase (low velocity, low wear) vs dilute-phase.
- For combustible dust (food/flour, wood, metals), ATEX-compliant equipment (explosion panels, flame arresters, isolation) is required.

## Frequently asked questions
Q: Who is MDSJ Process?
A: A Turkish manufacturer (founded 1986) of industrial air pollution control and pneumatic conveying systems, marketing its products under its own DUCON brand. Turnkey design-to-commissioning, 4,500+ projects, exports to 40+ countries.

Q: Is DUCON the same as the US "Ducon"?
A: No. DUCON is MDSJ Process's own registered trademark (EUIPO + Turkey), independent and 100% Turkish-owned; not affiliated with or licensed from US Ducon.

Q: What is a wet scrubber and when is it used?
A: A device that removes particulate and/or soluble gases (SO2, acid gases, odor) from a gas stream using a scrubbing liquid. Used when dust is sticky/sub-micron, gases are soluble, temperatures are high, or there is explosion risk.

Q: Baghouse filter vs electrostatic precipitator (ESP)?
A: Baghouse (fabric) filters generally achieve higher fine-particulate efficiency and handle variable loads well; ESPs handle very high gas volumes at low pressure drop. MDSJ Process supplies dry filtration (baghouse/jet-pulse/cartridge) and wet systems and selects per process.

Q: Do you deliver turnkey?
A: Yes — in-house design, manufacture, installation and commissioning of the complete system.

Q: What certifications do you have?
A: ISO 9001:2015 (quality), ISO 14001:2015 (environmental) and ISO 45001:2018 (occupational health & safety) management-system certificates issued by FQC; CE marking under the Machinery Directive 2006/42/EC (notified body QA Technic) for our wet scrubber, jet pulse bag filter and radial fan product families. ATEX-compliant design is available as an option for explosive-atmosphere processes.

Q: Which industries do you serve?
A: Cement, iron-steel & foundry, power, biomass, hazardous-waste incineration, chemical/petrochemical, mining, glass/ceramics, food & beverage, wood/MDF & paper, plastics & rubber.

Q: How can I get a quote?
