Deoriser makes a difference compared to other scrubbers!
Four features of Deoriser
1 Capturing odors and dust
To say nothing of various odor-causing substances, fine powder dust can be captured reliably as well by the water film.
2 Capturing with water film
Water film formed on the screen realizes 100% gas-liquid contact efficiency.
3 Easy maintenance
Compared to conventional-type scrubbers, running costs are greatly reduced.
4 Minimizing sludge generation
The air diffusion device Aquablaster is installed. Water putrefaction is prevented to minimize sludge generation.
Water film type Scrubber Deoriser is an earth environment-friendly high performance scrubber equipped with a circulating water purification unit.
1 Capturing odor components and fine powder dust
Odors and dust are captured without fail.
2 Realizing 100% gas-liquid contact with water film
About 40 mm of water film shuts exhaust gas out.
3 Adopting a cartridge-type screen
Replacement is easy with a screen 50 cm square.
4 Incorporating the Aquablaster
Water putrefaction is prevented to enable long-term use of circulating water.
Next-generation deodorizing system that revolutionized the traditional concept of deodorization “Water film type Scrubber Deoriser”
Employing water film, high gas-liquid contact efficiency is realized to capture odor components without fail.
The interior of the tank is equipped with a diffusion pipe Aquablaster unit that biodegrades organic matter added to the water,
which minimizes circulating-water putrefaction and sludge generation, enabling long-term closed water circulation.
Water film type Scrubber Deoriser is a next-generation ultra-high-performance dust collection and deodorization unit that completely eliminated the weak points of conventional water cleaning scrubber type deodorizing equipment.
Unbelievable capturing power! Compare with other scrubbers!
Up to this volume was captured only in a few hours!
Here's the difference with other scrubbers!
- Capturing with water film ensures that odors and dust are captured without fail!
- Cartridge type contact material makes maintenance easy.
- Built-in high-performance diffusion pipe Aquablaster minimizes sludge generation and prevents water putrefaction!
Features of the Water film type Scrubber Deoriser cleansing deodorization unit
High gas-liquid contact efficiency is realized by forming water film on screens.
Easy-to-replace cartridge type
Hard to clog and makes pressure loss hard to change
The water film type Scrubber Deoriser prevents water from putrefying and makes sludge generation difficult.
The water film type Scrubber Deoriser responds to a wide variety of odor-causing substances in diverse plants.

Why is water film necessary? Necessity of water film
Examining things at the microscopic level…
The width of net-type infill material is approximately 2 mm and the openings approximately 5 mm. Looking at the microscopic level, odor-causing particulates have a diameter of one to five microns, and the water droplets that dislodge these particulates are about 150 microns in diameter.
If we multiply these measurements by 1,000, we can visualize the particulates as 1 mm to 5 mm specks, and the water droplet the size of a softball, 15 centimeters across.
Now visualize the infill material as being the width of a narrow road – two meters – while the openings are five meters in width, and it is easy to see why the gas-liquid contact is poor.

*An organic solvent may melt FRP and PVC.
*Including Deoriser, there is no perfect deodorization method. We recommend carefully checking and determining a treatment method by eliminating ineffective ones.

By clarifying at which point the customer can be satisfied in a demonstration, various risks can be resolved.
Deoriser circulating water treatment methods
1 Settling tank purification method
This is a method in which water that has finished circulating is transferred to a separate tank and gradually treated. For example, five tons of circulated water treated over 90 days means that only 55 liters of water needs to be treated per day, minimizing the load on wastewater treatment facilities and enabling diluted discharge.
2.Water-treatment system simultaneous use method
This method entails installing an Aience unit tank side by side with the Deoriser and regularly purifying and discharging water. Depending on the rate of water circulation, oil separating system or coagulator may also be used. This method is geared toward businesses without wastewater treatment or sewage water facilities.
3.Sewage water discharge method
Circulating water is discharged at appropriate intervals at levels permissible under sewage water discharge standards. At first, it is necessary to perform a series of data measurements and determine the length of use that will result in levels exceeding the sewage water discharge standards. However, once these have been performed this is a highly labor saving method.
|Application||Duration between circulating water exchanges|
|Paint drying furnace exhaust gas treatment||1 to 4 months|
|Chemical factory exhaust gas treatment||1 to 4 months|
|Food factory exhaust gas treatment||1 to 4 months|
|Restaurant exhaust gas treatment||3 to 6 months|
4.Industrial waste method
Circulating water is used continuously for as long as possible, and then disposed of as industrial waste. This method does not meet zero-emission targets, but it is suitable for businesses without wastewater or sewage water treatment facilities. The cost is reasonable as well, with five tons of circulating water being used for five months resulting in a per-ton cost of 35,000 yen, or 1,170 yen per day.
5.Fixed-quantity water injection method
Fixed quantities of water are injected, controlled by a solenoid valve, keeping the circulating water continually overflowing and water being discharged within the permissible water discharge standards. This method is largely geared toward businesses with access to groundwater or other reasonably priced water sources.
