Below 150mm Aq |
over 350mm Aq |
| Secondary pollution & Noise |
Low (Non fly ash) |
High (Fly ash generated) |
| Installation cost |
Low due to small-size facility(High initial cost acc. the absorbent material price) |
High due to large-size facility (Low initial cost, but additional cost increases) |
| Maintenance cost |
Low by reusing of generated absorbent materials |
High due to the exchange cost of total activated carbon |

Adsorption
The adsorption is one of deodorization methods to remove odor substances by solid adhesions with simply equipment, but not suitable for high concentration and large volume of treatment.
Activated carbon, which is applied to most gases, is used as adsorption materials. Equipment is classified to regeneration type and non-regeneration type depending on the adsorption materials.
Applications & Features
-
Regeneration type
-
: 1. High removal Rate
: 2. Various application from low to high grade in concentration
: 3. Not suitable for odor substances with non-condense components due to the necessity of a seperated process to treat gases from adsorption materials
-
Non-regeneration type
-
: 1. Regular exchange necessary of adsorption materials
: 2. Low installation cost & easy maintenance
: 3. Suitable for sites with irregular odor generation
Absorption
The absorption is an odor removal method by absorption liquid, which is the most widely used in industries.
It has low installation cost, easy maintenance and high stability, but less effective than ACF's.
Correct absorption liquid selection and appropriate equipment is the most important part for maximized result.
| Neutralizing absorbent |
Acid : Dilute sulfuric acid, Hydrochloric acid
Alkali : Caustic soda
|
| Oxidizer |
Hypochlorous Acid Water, Chlorine water, Chlorine disxide, Porassium permanaganate etc. |
| Solvent |
Nonvolatille petroleum, Esters |
