Biodeoriser is a revolutionary scrubber that captures odors and dust with a waterfilm and filters air through circulating water for purification.



Deoriser is the next-generation system that revolutionizes the entire concept of deodorization.

The water film provides excellent gas-liquid contact efficiency, reliably capturing odor-causing substances. The interior of the tank is equipped with an Aquablaster unit that biodegrades organic matter added to the water, which minimizes circulating-water putrefaction and sludge generation, enabling long-term closed water circulation. The next-generation, ultra-high-efficiency dust collection and deodorization system that does what water cleansing scrubber deodorizers can’t, Deoriser is the clear choice for your deodorization needs.



Deoriser acts on a wide variety of odor sources in all kinds of factories and businesses.

Deodorization methods and business applications


*Deoriser technology combines cleansing and biological deodorization.


Examining things at the microscopic level…

The width of net-type infill material is approximately 2mm and the openings approximately 5mm. 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 1mm to 5mm 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’s easy to see why the gas-liquid contact is poor.

Bio 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.

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.
