Most wastewater treatment processes are based on
the natural assimilative capacity of our lakes,
streams, and waterways. This natural cleaning process
is based on aerobic bacteria consuming wastes and
rendering them harmless. By and large the effectiveness
of these processes is limited by the ability to
deliver sufficient oxygen to the bacteria to continue
the assimilative process. In the over 100 years
that these processes have been operated, great strides
have been made in the technology to get oxygen to
dissolve into water for use in the treatment process.
Unfortunately, the solubility of oxygen is quite
low (on the order of 10 mg/l) when compare to the
Biochemical Oxygen Demand (BOD) exerted in municipal,
industrial and agricultural wastewaters (typically
between 180 mg/l up to 200,000 mg/l of BOD). Since
a pound and a quarter of oxygen are required to
consume a single pound of BOD (and 4.6 pounds is
required to consume a pound of Nitrogen (TKN)),
high volumes of air (only 20% O2) must be introduced
into the wastewater to encourage bio-degradation.
The efficiency of this transfer is fraught with
challenges.
DynamOx assures that every pound of oxygen delivered
to the process is made available to the consuming
bacteria with no loss to the atmosphere. While
the technology is applicable to all biological
wastewater treatment process, it is particularly
attractive to those situations in which the physical
constraints make standard aeration equipment unattractive.
These include high strength wastewaters, shallow
water applications, wastewater with odor concerns
and groundwater.
