Zhengzhou Enviro Solutions is the international brand of Guangdong Zhengzhou Environmental Protection Technology Co., Ltd., a Foshan-based manufacturer and engineering provider for industrial waste gas treatment systems. We configure equipment for VOCs, acid mist, odors, dust, smoke and corrosive exhaust according to the actual process conditions—not a one-size-fits-all removal claim.
For faster selection, send airflow, pollutant composition, inlet concentration, temperature and the required outlet limit with your enquiry.
Choose the treatment process by pollutant and operating condition
The same pollutant name can require a different system at another plant. Our first step is to define the source, concentration range, airflow variation, chemistry, safety constraints and compliance target.
| Pollutant / source | Typical examples | Candidate process | Key selection point |
|---|---|---|---|
| Acid and alkaline mist | HCl, H₂SO₄, HF, NH₃ and pickling or plating exhaust | Packed wet scrubber or cyclone-hybrid spray scrubber | Selected by gas solubility, reagent chemistry, corrosion risk and mist loading. |
| VOCs | Coating, printing, chemical and solvent exhaust | Activated carbon, zeolite concentration, catalytic oxidation or RTO | Selection depends on concentration, airflow, composition, temperature and safety limits. |
| Odor | H₂S, NH₃ and biodegradable wastewater or process odors | Biofilter, chemical scrubber, carbon polishing or ionization | Humidity, biodegradability, variability and required redundancy drive the treatment train. |
| Dust, smoke and aerosol | Dry particulate, sticky dust, fumes and fine liquid droplets | Pulse-jet baghouse, wet scrubber or wet electrostatic precipitator | Particle size, resistivity, moisture, temperature and fire risk determine the separator. |
| Laboratory exhaust | Variable acid, alkaline and organic fume-hood streams | Corrosion-resistant ducting, scrubber, dry filter and carbon stages | A source-by-source review avoids incompatible chemicals entering the same treatment stage. |
Published equipment ranges from our supplied catalog
These figures describe standard model ranges in the current manufacturer catalog. They are useful for early screening, but they are not a final guarantee: pressure loss, residence time, reagent demand, fan duty and emissions performance must be recalculated for each project.

Information required for equipment selection
A quotation based only on duct diameter or total airflow is incomplete. Provide the following inputs so the engineer can define the process train, materials, fan duty, controls and operating cost.
- Airflow for each operating condition (m³/h)
- Pollutant names and inlet concentrations
- Gas temperature, humidity and particulate loading
- Required outlet limit or applicable local standard
- Operating hours, batch cycles and expected variation
- Corrosive, flammable, explosive or condensable components
- Available footprint, duct route and stack arrangement
- Site voltage, frequency, installation location and climate
- Destination country, delivery scope and commissioning needs
Typical engineering scope
Source review, process selection, equipment and duct sizing, corrosion-resistant material selection, controls, fabrication, delivery documentation, installation guidance and commissioning support.

Waste gas treatment system FAQ
Which system should I use for industrial waste gas?
There is no universal process. Airflow, composition, concentration, temperature, humidity, safety risk and the required outlet limit must be reviewed together. A wet scrubber may suit soluble acid gas, while VOC exhaust may require adsorption, concentration or oxidation.
Can you quote from airflow alone?
We can give an initial equipment range, but a responsible proposal also needs pollutant data, temperature, operating schedule, corrosion and explosion risk, site voltage, footprint and discharge requirement.
Do you supply individual equipment or a complete treatment line?
Both scopes are available. The supply can cover a scrubber, biofilter, adsorption unit or fan, or an engineered train including pretreatment, core treatment, ducting, controls and installation guidance.
Are catalog airflow ranges guaranteed for every application?
No. Catalog figures identify available standard sizes. Final airflow, pressure loss, materials, media volume, reagent demand and performance requirements are confirmed in the project-specific technical proposal.
