The IC-SEP* system
exploits the density difference between two phases primarily by
attaching air bubbles to one phase and floating it away for collection.
This idea is not new, but the method by which it is achieved using
the IC-SEP* is set to revolutionize how we think about DAF systems.
The IC-SEP* works by dissolving
free air from the atmosphere in a cyclone within the unit, which
allows up to five times more air to be dissolved than a traditional
DAF system. The pressures and forces created ensure intimate mixing
of the air and the fluids to be separated, which causes the air
to be fully dissolved rather than entrained. The pressures generated
within the IC-SEP* are up to two times that created in traditional
DAF systems thereby, further increasing the amount of air available
to strip out suspended solids.
The IC-SEP* unit was designed
with no moving parts. The fluid spins itself through specially designed
channels, and because this is achieved without moving parts, maintenance
costs are reduced significantly.
To realize effective effluent
separation, it is often necessary to adjust the electro-potential
(pH) of the wastewater, in addition to utilizing an air floatation
system. It is also possible to use chemicals such as coagulants
and flocculants to help create surfaces or structures that can easily
attach to the air bubbles. Coagulants are used to bind the particulate
matter together and flocculants are used to change the surface tension
on the liquid/solid and or liquid/gas interfaces. The combination
of all three regimes will almost always bring about separation.
However, using the IC-SEP* technology, it is usually sufficient
to utilize one or two of these regimes and still accomplish a satisfactory
result. |
