DynamOx efficiently introduces oxygen (and
only oxygen) into the offending liquid without driving
off the offending odors. This allows superior odor
control as anaerobic wastewater can instantly shift
to an aerobic state without "stripping"
noxious gases from the waste stream. In some difficult
wastewater, the chemical reaction can be accelerated
using standard, non-toxic catalysts.
All of the oxygen delivered is also available
for rapid BOD, ammonia, and phosphorous reduction.
When organic materials are consumed by bacteria,
an electron is released. The metabolic process
that consumes BOD generates electrons so compounds
that serve as electron acceptors are required.
In an aerobic liquid, that electron would prefer
to attach to an oxygen molecule. If no oxygen
is available, it attachs to other compounds. Without
discussing the "maximizing the yield of free
energy" it suffices to say that material
such as ammonia, hydrogen sulfide, and methane
are formed. The addition of oxygen shifts the
ORP (oxygen reduction potential) and changes the
form of these materials and, for example, Hydrogen
Sulfide gas is eliminated and becomes a less noxious
form of sulfur. The accompaning figure depicts
how ORP affects the form of sulfur in a liquid.
The process of increasing the ORP to eliminate
H2S has been well known for years but typical
aeration equipment used bubbles to introduce the
oxygen. The aeration process encourages the H2S
to "off-gas" and increases the H2S concentrations
in the air.
