is a tough andlow running cost product.
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 aswell by the water film.
This picture shows the sludge collection section.

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 sludgegeneration
The air diffusion device Aquablaster is installed.
Water putrefaction is prevented to minimize
sludge generation.

We recommend carefully checking and determining atreatment method by eliminating ineffective ones.

It is possible to carry out a demonstration experiment in the actual place.
By clarifying at which point the customer can be satisfied in a demonstration, various risks can be resolved.

■ Deoriser circulating water treatment methods
Settling tank purification method

Water-treatment system simultaneous use method

This is a method in which water that has finished circulating istransferred 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 andenabling diluted discharge.

This method entails installing an Aience unit tank side by sidewith 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 isgeared toward businesses without wastewater treatment or
sewage water facilities.

Industrial waste method

Fixed-quantity water injection method

Fixed quantities of water are injected, controlled by a solenoid
valve, keeping the circulating water continually overflowing andwater 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.

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 forbusinesses without wastewater or sewage water treatment
facilities. The cost is reasonable as well, with five tons ofcirculating water being used for five months resulting in a
per-ton cost of 35,000 yen, or 1,170 yen per day.

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 datameasurements and determine the length of use that will resultin levels exceeding the sewage water discharge standards.
However, once these have been performed this is a highlylabor saving method.
