Industrial Waste Gas Treatment Systems
Custom-engineered exhaust gas purification for VOCs, dust, odors, acid fumes, and oil mist. Eight core technologies covering every industrial emission scenario. Factory-direct pricing, 40+ countries served.
Complete Waste Gas Treatment Solutions
Industrial emissions contain a complex mix of pollutants — VOCs, acid gases, dust, odors, and oil mist. Different pollutants need different technologies. That’s why we manufacture eight distinct treatment systems, each targeting specific contaminant types.
We treat all major waste gas types:
- VOC emissions from printing, coating, and chemical synthesis
- Acid fumes from electroplating, pickling, and battery manufacturing
- Dust and particulates from mining, cement, and metalworking
- Odor from food processing, animal housing, and wastewater plants
- Oil mist from machining, frying, and cooking operations
Often, a multi-stage system gives the best results. For example: dust collector + wet scrubber + UV photolysis + activated carbon — each stage removing what the previous one couldn’t.
Technology Guide
Which Technology Is Right for Your Gas?
Match your pollutant type to the right treatment technology. Many projects need a combination of two or more.
| Pollutant Type | Recommended Technology | Removal Efficiency | Typical Industry |
|---|---|---|---|
| VOCs (low conc.) | UV Photolysis + Activated Carbon | 85-95% | Printing, coating, chemical |
| VOCs (high conc.) | Activated Carbon Adsorption + Desorption | 90-98% | Chemical, pharmaceutical, solvent recovery |
| Acid/Alkaline Gas | Wet Scrubber Tower | 90-99% | Electroplating, pickling, semiconductor |
| Dust & Particulates | Baghouse Dust Collector | 99%+ (down to 0.1um) | Cement, mining, metalworking |
| Odor & Malodorous Gas | UV Photolysis + Bio-deodorization | 85-95% | Food, animal housing, sewage plants |
| Complex Mixed Gas | Low-temp Plasma + Catalytic | 80-92% | Chemical, coating, pharmaceutical |
| Oil Mist / Fume | Oil Fume Purification Unit | 90-95% | Machining, frying, restaurants |

Selection Process
How We Design Your Waste Gas System
From gas analysis to commissioning, we handle the complete engineering process in four steps.
1
Gas Analysis
Share your exhaust volume, gas composition, and emission limits. We review your data to understand what needs to be removed.
2
Technology Selection
We match the right combination of technologies to your pollutants. Single-stage or multi-stage — based on what gives the best result at your budget.
3
Manufacturing
All equipment is built in our Qingdao factory. We test each unit before shipment and provide photos and videos of the completed system.
4
Installation & Support
Detailed drawings, remote guidance, or on-site supervision — your choice. Plus 12-month warranty and ongoing spare parts supply.

How do I know which waste gas treatment technology I need?
Start by identifying your main pollutants (VOCs, acid gas, dust, odor, oil mist) and their concentrations. Send us your gas analysis report or tell us about your production process. Our engineers will recommend the right single or multi-stage system based on your specific conditions and emission targets.
What is the typical lead time for a waste gas treatment system?
Standard units typically ship in 2-3 weeks. Custom-engineered systems take 4-8 weeks depending on size and complexity. We provide detailed drawings within 3 days of order confirmation and keep you updated throughout manufacturing.
Can you handle installation and commissioning?
Yes. We offer three options: detailed installation drawings with remote guidance, video call supervision, or on-site installation by our engineers. Most systems are straightforward to install with our guidance. We also provide commissioning support to ensure everything runs correctly.
What is the maintenance requirement for these systems?
Maintenance varies by technology. UV lamps need replacement every 8,000-10,000 hours. Activated carbon needs replacement or regeneration every 6-12 months. Baghouse filters last 1-3 years. Wet scrubbers need periodic pump and nozzle checks. We provide a detailed maintenance schedule with every system.
Do you offer OEM or custom branding services?
Yes, we offer OEM services for distributors and system integrators. We can manufacture systems to your specifications and with your branding. We also provide technical training and marketing support for our OEM partners.
