Dry Reactor (DR)
Alongside its filter bag manufacturing, Micro-one Co., Ltd. designs and builds waste incinerators, flue gas treatment systems and power plant dust collection equipment on an EPC basis. Designs are checked with CFD flow analysis and 3D modeling, and every system can be fitted with Micro-one’s own DuraFill™ and CataFill™ filter bags.
We offer cost-effective consulting tailored to each customer and provide after-sales service once the plant is handed over.

A DR (dry reactor) injects dry hydrated lime and activated carbon powder into the flue gas to neutralize acid gases (HCl, SOx, HF) and adsorb dioxins and heavy metals. It uses no water, so there is no wastewater or sludge, and the structure is simple; the injected sorbent reacts again on the surface of the downstream baghouse filters before it is captured. Micro-one’s DR injects solid lime and activated carbon to remove residual acid gases and dioxins together as a secondary treatment stage.
As a dry process, it produces no wastewater or sludge, reducing wastewater treatment costs
Effectively removes acid gases such as SO₂, HCl, and HF
Works with the downstream baghouse, which captures fine dust at the same time
The simple design suits small installations and a wide range of industries
Lower corrosion risk than wet systems keeps maintenance relatively simple
Removal efficiency may be lower than semi-dry (SDR) or wet systems; sorbent consumption may be higher
Lower installation and maintenance costs
Acid gas treatment for municipal and medical waste incinerators
Boilers, power plants, steel mills, and various industrial sites
Processes that emit acid gases
Where acid gas concentrations are low, a DR can be used alone. It is less efficient than an SDR and can use more sorbent, so incinerators usually place it after an SDR as a secondary stage.
To adsorb dioxins and heavy metals such as mercury. The spent carbon is captured in the downstream baghouse.
Yes. The sorbent builds up and reacts in the dust layer on the filter surface. DuraFill™ ePTFE membrane filter bags capture dust at the surface and keep the pressure drop low.
