Regarding the use of a vortex for reducing minerals in
seawater.. the vortex created by the high speed rotating member on the mixer
acts as an enhancement to a complex set of events that we have finally been able
to replicate. We actually achieved a sustained oxidation reduction of minerals
in water. The vortex produces the
"oommph" . Inducting air at the periphery of the
rotating ( 110 f/p/s velocity) member permits a velocity shear sufficent
to partially oxidize the entrained minerals in the water. An active cavitation
event is present at this time. The trick was to keep the cavitation bubble in
suspension and away from the inner shroud wall or the wall dissappears rapidly
The vortex swirl is sufficent to perform this balancing act. Based on the
residual in the bottom of the test tank, we calculate we had a
mineral reduction of 10-15%. Why such high hopes for
achieving 40% or more ?
Most seawater desal plants use a battery of
filters upstream of the reverse osmosis battery of membranes.
Some are experiencing clogged filters on 2 hour
intervals so they add an expensive chemical for descaling. Any reduction of
minerals prior to filtering is money in the bank. We have a long difficult path
to traverse to reduce the electric power used but that again is mostly grunt
work.
Best guess why the vortex gives the "oommph" is it "
triggers" the cavitation event. Add to that is the shape of the
parabolic shroud and it becomes an " echo chamber" similar to a
speaker.
Please do not misunderstand.. we are NOT making a claim
that the vortex has " magic" powers.
