The Honeycomb Wet Scrubber achieves over 95% removal efficiency for various mixed acidic gases over a 3.5-year period.

The system operates with a very low pressure drop (49–78.4 Pa) while maintaining minimal scaling.

It outperforms traditional packed wet scrubbers by requiring a shorter height and offering lower resistance.

The technology is proven to be a practical long-term solution for semiconductor exhaust treatment.

Research on Taiwan night markets reveals that cooking fumes contain hazardous carbonyl compounds and polycyclic aromatic hydrocarbons (PAHs).

Fume toxicity and emission levels increase significantly during grilling and when sauces are added to food.

Formaldehyde dominates carbonyl emissions (71 - 96%), while naphthalene accounts for over 70% of total PAHs.

Controlling these fumes is crucial because they pose exposure risks to vendors and nearby populations, highlighting the need for better urban air pollution policies.

Near-zero emission of PM2.5, SO2, and white smoke technique for practical industrial application.

Exhaust gases ( and ) from a sintering plant are treated sequentially through a cooling tower, a honeycomb wet scrubber, and a novel WEP with PJWF.

The honeycomb wet scrubber effectively targets  gas, achieving an impressive removal efficiency of 99.7%.

The novel WEP with PJWF captures charged fine particles () with a high removal efficiency of 99.3%.

The multi-stage system achieves near-zero emissions, reducing  to 0.33 ppm,  to , and opacity down to 0.13%.

A survey of 21 incinerators in Taiwan showed high startup POP emissions (chlorinated and brominated) driven by ash deposits, flue-gas bypass, and combustion instability.

Low-cost operational measures were introduced, including cleaning ash deposits, shortening heating time, eliminating flue-gas bypass, and advancing activated carbon injection.

Full-scale trials demonstrated over 92% reduction in chlorinated POPs and over 88% reduction in brominated POPs, suppressing de novo reformation and adsorptive memory effects.

Feasible startup procedures enable simultaneous control of persistent organic pollutants from waste-to-energy incinerators in an operationally simple manner.
