is well suited for golf course ponds, dugouts, wastewater treatment
lagoons, aquaculture systems and other applications where
aeration systems are required.
How does it work?
O 2 b2 Aeration Tubing is a unique dual, self-ballasting,
thermoplastic elastomer compound extruded tubing. The
primary tube has a multitude of tiny holes, arranged in a
specific pattern, emitting and controlling a steady stream
of air bubbles ranging from 1/100" to 1/16" when
pressurized. The secondary tube is filled with
environmentally friendly silica sand of various
compositions, serving as ballast for the dual assembly.
The O 2 b2 is laid out
strategically in the water body and is powered by a
low-pressure compressor. As tiny bubbles are released from
the tubing at the bottom of the pond, they rise at a rate of
less than one foot per second (laminar flow). At this rate
of ascent, the bubbles do not cause turbidity. As these
bubbles rise, they expand and thus give off energy. As we
know, when energy is given off, so then is heat. Therefore,
by aerating in this fashion we are gently reducing the
temperature of the lake. This is then the first stress we
place on the algae and plants in the water. We also know
that cooler water retains more oxygen than warmer water,
which is a benefit to all marine creatures in the lake.
Why a bottom aeration
One benefit to a bottom aeration system is the mixing
capability. As the bubbles rise and expand, they increase
their surface area and a vacuum is formed below each bubble.
This draws the water from the bottom of the lake towards the
top, and then as the bubble bursts at the water surface it
breaks the surface tension of the water. This allows more
oxygen to transfer back into the water. It is in the mixing
process that the thermoclines in the lake are eliminated,
allowing fish and insects to live in the entire water
column. Also, hydrogen sulphide and methane are no longer
produced as the sludge layer changes to aerobic conditions.
This eliminates odours and dangerous gases.
Once I have the system in
place, what’s next?
After Aquatech installs the aeration system, we then
augment the water with beneficial non-pathogenic bacteria.
The bacteria flourish in all the excess nutrients that the
sludge provides. As the many strains of bacteria devour
these nutrients, they break them down into carbon dioxide
and water as well as inert ash and single elements. The cell
bodies of the bacteria then become part of the food chain,
eaten by zooplankton and small insects, which in turn are
eaten by larger animals such as fish and birds. It is with
this process that the nutrient load of the lake is channeled
away from plants and algae and toward higher life forms.
