the system design status quo?

Everything is functioning as designed…
but unpleasant odors and large amounts of sludge
are generated anyway. That’s because wastewater
isn’t being treated effectively!
Contact Aience without delay. We’ll tell you about
our optimal system that offers a “new definition”
of wastewater treatment for the future!

Were you aware that no matter how impressive a system is,
if it is generating more unpleasant odors and sludge more than necessary,it is basically not achieving treatment of wastewater?
With the innovative Aquablaster diffuser developed by Aience,and our design theory based on a "new definition,” putrefactionthat is the source of foul odors does not occur, andsludge treatment is no longer necessary for sewage discharge,.
Although it seems to do something impossible according to conventional wisdom thus far,our system is backed by technical strength cultivated through collaborative researchwith universities and enterprises, and an extensive track record in and outside Japan.
Furthermore, its outstanding wastewater treatment power has been recognized internationally,
and it was adopted as a model ODA project for Vietnam in 2016.
Aience is redefining wastewater treatment for the future,and the message is reaching the world.

“New Definition”:
Activate microorganisms by increasing
the concentration of dissolved oxygen in the tank,and finely pulverize sludge so
the microorganisms easily decompose it.
“New Definition”: Protrusions are locatedin the center of the diffusing tube.
The closer liquid gets to the center, the faster it moves… in otherwords, the higher its energy. However, for some reason, thus fardiffusing tubes have had protrusions located in outer areas whereliquid flow is slow. For this reason, the patented technology ofAquablaster has protrusions located at the center and generates
microscopic bubbles with powerful force.

If we adhere to conventional system design, it is impossible to❶ "New definition" of required air volume
Q●
Why are unpleasant odors (hydrogen sulfide) emitted even though
the required air volume meets design specifications?

A●

This is because according to conventional calculations,“it is not possible to supply enough air for microorganisms toconvert organic matter into energy.”

When calculating the necessary amount of air with conventional
design guidelines, the air volume required is approximately 20 to 25
liters per min per cubic meter of the tank, but with this air volumeindustrial wastewater with a higher load than sewage cannot be treated effectively, and hydrogen sulfide and excess sludge are generated.
Since Aience calculates the amount of air required specifically foreach worksite using a “new definition” reverse-calculated based on
empirical values, we are able to minimize hydrogen sulfide generation
and reduce organic matter to the greatest extent possible with aerobic degradation.

“Set your mind at ease.”
Even if air volume is increased, with low-pressure-loss
Aquablaster, electricity bills will scarcely change,and ifanything will be lowered.

Caution

The above values are air volumes when Aquablaster isused. Treatment efficiency will not increase if this amountof air is delivered to an existing installed diffuser.

❷ "New definition" of oxygen dissolution efficiency
Q●
Why are there no standard figures for oxygen dissolution efficiency even though
there are systems with excellent oxygen dissolution efficiency?

A●

Do not be deceived by oxygen dissolution efficiency figures:
because “the higher the wastewater load,
the more difficult it is for oxygen to dissolve.”

The numerical values for oxygen dissolution efficiency are freely calculated by each manufacturer using their chosen method, without aconsistent measurement standard such as JIS. What is important is
not oxygen dissolution efficiency, but whether or not wastewater istruly treated effectively. As evidence of this, in wastewater treatment
at a chicken processing plant (see section below), we did not use anypressurized flotation equipment, and met the standards for sewage
discharge with only Aquablaster and bio treatment.

When load is high, as shown in the figure, oxygen does not easily
dissolve and the DO value differs even with the same air amount. We
could say that it is dangerous to overemphasize dissolution efficiencyof the diffuser when designing the system. *DO: dissolved oxygen concentration

❸ "New definition" of microorganisms
Q Why are results not improving despite introduction of optimal microorganisms?
●A●Because attention must be paid not only to the type of microorganism,
but also to what kind of metabolizing is performedby microorganisms in the tank.

No matter what high-performance microorganisms are introduced, if insufficient oxygen isavailable for decomposition, no effect will beobtained. How to induce “metabolism with totally aerobic respiration” is an extremely crucialfactor.

JIS (Japan Industrial Standards) do not set any standard foroxygen dissolution efficiency. As a result, currently each manufacturer measures it independently and publicizes the figures.
This is not a problem in and of itself, but when these figures aresuperimposed on the graph at left, the contradictions cannot
be denied. Aience calculated oxygen dissolution efficiency inthe corner area of a water tank measuring 1800 width x 1800
horizontal depth x 5000 water depth (unit: mm), but the results
are only an indicator. Please be aware that “it is not oxygen
dissolution efficiency that performs water treatment.”
Please refer to the power differential table on p.6.
