1. Outline of Equipment

There are two major approaches in deodorization. One utilizes adsorption to remove odor, and the other changes odorous substances into something else to reduce or eliminate odor. The former is represented by adsorption using activated carbon and the latter by the oxidation of the odorous substances.
In oxidation, chemicals are commonly used for the adsorption and oxidation of odor by scrubbers. In addition to feeding of chemicals and intricate operation, this method causes environmental burden as it produces effluent water.
Plasma deodorizer generates high-voltage corona discharge within the odorous atmosphere, generating active molecules, radicals and ozone to oxidizes odorous substances. It does not use oxidizing chemicals or water used in the conventional deodorizers. It only requires electricity, the clean energy, creating no burden on environment in itself.

2. Features

1. Easy operation and maintenance
On-off switching is the only procedure needed for operation. It can be operated without an operator, or can be controlled remotely by discharge monitoring.
2. Low environmental burden
There is no emission of chemical, CO2 or NOx.
3. Low operating cost
Oxidation of normal odor uses only 250-500W per 1,000m³/h of treatment.
4. Small footprint
It occupies a small floor area, as there is no peripheral equipment.
5. Easy installation
The unit is built on top of a standard pallet as a package. Shipping and installing is easy.

Specification

Stainless steal is its main building material.

3. Performance

The combination of the following four reactions of "DEODOLESS"oxidizes odorous substances.
1. Generation of active molecules by the corona discharge. The corona discharge energizes the molecules of the gas, generating active molecules and radicals.
2. Deodorizing by the radicals
The active molecules and the radicals collide with the odorous substances and oxidize them.
3. Direct oxidation of odorous substances by the collision of electrons The electrons discharged from the Discharge collide with the odorous substances and destroy them.
4. Oxidation by the ozone
Ozone, a by-product of corona discharge, oxidizes the odorous substances.

4. Application

- Food-processing odor from garlic, onion, cocoa beans and fish
- Feed-processing odor
- Fertilizer-producing odor
- Exhaust odor from amino-acid extraction plant
- Odor from effluent-water treatment facility of food-processing factory
- Odor from landfill for wastes
- Odor from digesters
- Other kinds of odor
