Simple Rock-Wool-Type Deodorizing Equipment1. Equipment overview
Population in suburban areas is growing, making the odors generated from stock-raising facilities an increasingly important problem.
This equipment removes odors generated from stock-raising facilities by utilizing bio-decomposition. It eliminates the shortcomings inherent in the conventional soil deodorizing process.
The odor-causing gas (ammonia) generated from a stock-raising facilities is made odorless through bio-decomposition by being blown upward from the bottom of the equipment.
Stable deodorizing performance is maintained by using a special rock wool mixture as the microbe carrier. It does not need replacement as it is made from inactive material, and can be used semi-permanently.
The extremely low filtering resistance results in very low operating costs compared with other deodorizing equipment.
2. Features
a. Microbe-assisted odor removal utilizing biological decomposition
b. Reliable conversion of unacceptable odors into odorless gas
c. Low fan operating cost by employing rock wool deodorizing material with low air resistance. Conforms to the Agriculture, Forestry and Fisheries Ministry's Urgent Development Requirements
d. Required installation area is less than one fifth of that needed for conventional soil deodorizing equipment.
e. Fully automatic operation eliminates the need for operation personnel
f. Deodorizing performance is maintained even in cold climate areas
g. Re-circulation of drainage water results in very limited environmental impact.
