The textile industry is characterized by a wide range of processes, including fiber production, spinning, weaving, knitting, dyeing, finishing, and printing. These processes often involve the use of numerous chemicals and generate significant amounts of waste gas containing various pollutants. These pollutants can include:
| Technologies | Principle | Features | Applications |
| Absorption | This method uses a liquid absorbent to capture soluble pollutants from waste gas by selective dissolution or reaction. | Highly effective for removing acidic gases (e.g., sulfur dioxide, hydrogen chloride) and some VOCs. Customizable with different absorbents for target pollutants. | Suitable for treating waste gas from dyeing, finishing, and chemical processing. |
| Adsorption | This technique employs solid adsorbents like activated carbon to trap pollutants on their surface through physical or chemical forces. | Versatile for removing a wide range of VOCs and odorous compounds. Adsorbents can be regenerated for reuse, improving cost-effectiveness. | Widely used for VOC emission control in dyeing, finishing, and printing, as well as odor control in wastewater treatment. |
| Catalytic Oxidation | This method uses a catalyst to accelerate pollutant oxidation into less harmful substances (e.g., CO₂ and H₂O) at lower temperatures. | Efficient for VOCs and odorous compounds. Operates at lower temperatures than thermal oxidation, reducing energy consumption. | Suitable for waste gas from dyeing, finishing, and coating processes. |
| Biofiltration | This environmentally friendly approach uses microorganisms to degrade pollutants into harmless byproducts in an organic bed. | Sustainable and cost-effective for treating VOCs and odorous compounds. Minimal secondary waste generation. | Effective for dyeing, finishing, and printing waste gas, and also for odor control in wastewater treatment. |
| Advanced Oxidation Processes (AOPs) | AOPs utilize powerful oxidizing agents such as ozone or hydroxyl radicals to break down and mineralize a wide range of organic pollutants. | Highly effective for recalcitrant pollutants resistant to conventional methods. Handles fluctuating concentrations and diverse pollutant mixtures. | Suitable for complex waste gas streams containing VOCs, odorous compounds, and inorganic pollutants. |
