Air diffuser for water treatment, chemical reaction.OHR AERATOR


OHR AERATOR is the only air diffuser in the world
that lives up to the name “The ultimate Air Diffuser”.

As you know there are many air diffusers on the market for wastewater treatment.
Unfortunately most of these air diffusers require replacement, cleaning and
maintenance constantly. As a result many wastewater treatment facilities have to
deal with constant serious after care problems.
OHR AERATOR is the best air diffuser on the market. It has the only mixing function
in the world and a unique mechanism. It is the “ultimate air diffuser” .


Never clogs.

Only one large diameter (30mm) hole for air discharge opening.

Most air diffuser manufactures claim “no clogging” or “reduced clogging”
for their equipment. However if you have ever worked in a wastewater
treatment facility, you will have experienced clogging with these air diffusers.
It’ s hard to find the true no clogging air diffuser. Please see the reasons
why OHR AERATOR doesn’t clog, and find out whether our explanations
are true or not.


OHR AERATOR generates many fine bubbles.

Only one large diameter (30mm) hole for air discharge opening.

OHR AERATOR and rubber porous air diffusers are operated under the
same conditions, OHR AERATOR generates 3.3 times the amount
of fine bubbles (approx. 100μm size) than rubber porous air diffusers.
Why OHR AERATOR generates many fine bubbles even though the
air discharge opening is only one large diameter hole?
The reason is OHR AERAOTR has strong Gas-Liquid mixing function.

Alpha Value=1.0.

Strong mixing function which is also used for chemical reaction.

OHR AERATOR’ s big advantage is it is aggressively used for chemical
reaction acceleration when no conventional air diffuser can be used
because the OHR AERATOR has a very strong mixing function.

Therefore, for wastewater treatment, Oxygen Transfer Rate of OHR
AERATOR doesn’ t change between clean water and actual wastewater.
(Alpha Value is the important indicator to demonstrate true air diffuser
efficiency in wastewater. OHR has been using the Alpha Value=1.0 for
over 30 years in real cases in the field.)
The OHR AERATOR’ s high performance is unmatched in harsh conditions.

Only Air diffuser that has two functions.

Both “gas dissolving” and “sludge accumulation prevention” simultaneously.

OHR AEARTOR generates both coarse bubbles and microbubbles
simultaneously. The coarse bubbles generate a very strong upward
water flow which prevents sludge accumulation. The microbubbles
contribute to increase DO value. These two kinds of bubbles are
absolutely imperative for effective wastewater treatment.
In addition, strong upward and spiral water flow in the OHR AERATOR
will wash and clean continuously. Thus, no scale formation after 15
years use.

We will show you the required installation layout plan necessary in order to use OHR AERATOR.

Our installation layout plan is based on over 3,400 previous set ups.

Installation layout plan is critical for the most effective air diffuser use.
The unique OHR AERATOR air diffuser must be installed correctly to perform effectively.
We will draw up and submit to you the best installation layout plan without charge based on the tank size (length/
width/water depth) you want to install and other information.
Please be assured if you install the OHR AERATOR strictly according to OHR’ s installation layout plan you will achieve
the best results.
