MixAirTech System
- What exactly is the
MixAirTech System? It is a clean, oil-less air blower system that
furnishes volumes of air (SCFM) to a continuous open spiral multi-plane
membrane diffuser.
- What is the mechanism by
which the product performs? Non-contaminated (oil-less) gas greater
than 1–2 SCFM is run through MAT’s micro-porous diffuser. This diffuser
contains 10 times the surface area and 14 times the linear lift area of
most diffusers. This causes an increase in the number of bubbles and the
flow pattern caused by them. It also enhances the natural efficiency of
oxygen transfer and turn over (inversion). There are other outside factors
that effect performance: toxicity, temperature, depth, contaminate type
and level, holding time and surface area.
- Why is it important to use
clean, oil-less air? Air or gas that contains dirt, dust or oil will
foul the transport system as well as clog the diffuser over a period of
time. Also the oil-less air should not further contaminate the effluent
that is being cleaned up by the system.
- What makes the MixAirTech
diffuser work so efficiently? The MAT design allows for the
unrestricted low headloss delivery of gas evenly over the multi-plane
surface of the continuous membrane. Once the gas overcomes the surface
tension of the effluent and membrane, numerous small bubbles are emitted
uniformly over the entire surface of the membrane. They then rise slowly
to the surface. These small bubbles:
- Rise more slowly than
larger bubbles.
- Have greater
cumulative surface than larger bubbles, and are emitted over the total
membrane.
- Create increased
interface over larger bubbles.
- Coalesce less than
larger bubbles.
- Channeled correctly by
design, affect a larger volume and surface area than larger bubbles.
- This natural
phenomenon along with the fact we have 10 times the surface area and 14
times the linear lift area of conventional devices assures superior
performance. All of this explains why MAT’s Twister TA22TM
diffusers have better certified test results than other diffusers on the
market today (see below).

- Another phenomena of
MAT’s design that cannot be measured, are the effects of continuous turn
over. There are no accepted certified tests currently available from the
mixing or aeration industries that measure this added benefit. Nature and
successful wastewater processing plants are dependent on continuous turn
over. There is additional air uptake from the surface of a body of water
that is not taken into account. Common sense dictates that MAT’s
diffuser efficiency is substantially greater than its certified ASCE
test results (ASCE recognized testing does not measure the effects of
surface absorption). This phenomena is due to our design, which causes
rapid continuous turn over. This helps eliminate stratification by
bringing bottom water to the surface and aggressively promotes increased
air absorption from an active agitated surface. In unrestricted clean
water it is estimated that these diffusers move 50,000 GPH per SCFM
between 2-10 SCFM.
- Why is the MixAirTech System considered relatively trouble free?
By using noncorrosive foul resistant materials that shed debris by design,
the MAT system will withstand nonstop heavy-duty applications. By having a
preventative maintenance program of increasing the PSI and CFM through the
diffuser on a regular basis, the biological/mineral build up is minimized.
The flexible membrane acts as a filter when you shut your system off. This
is another reason that the system resists fouling.
