So really, it's just sort of a short circuit.
Rather than go through the indoor space where the swimmers and the spectators and the lifeguards and everybody else is, it's just going straight outdoors.
Rather than going through the lungs of all those people I just listed and then outdoors.
That's exactly right.
So if you're familiar with pools and it sounds like you are, typically what will happen is water will flow over a gutter or over the edge of a gutter and it'll be fairly shallow in this gutter and then it'll move to a treatment system.
It'll be treated and then it'll be pumped back into the pool.
It's recirculated that way.
In this system, what they did was they designed intentionally a deep gutter so that there is quite a bit of depth to the, the water was maybe six or eight inches deep, something like that, but much deeper than you normally have in the gutter around a pool.
And then they put perforated pipes in the bottom of that gutter and they introduced compressed air to generate bubbles.
So those bubbles then would move through that six or eight inch deep water column.
And then they applied a
negative pressure or a vacuum to what's called the headspace.
That's basically the air above that water column and then draw that air off and then vent it to the outside.
And again, the idea there is it strips those chemicals, but does so in a manner that bypasses the place where people are breathing.
Yeah, it worked really well.
Yeah, it was quantifiably better.
So we had instrumentation set up at the Olympic venue in Paris and
And we were able to demonstrate that this system worked well.
I think that's an accurate statement.
I would say that when we first started this work, we identified 11 compounds that we found in every chlorinated pool that we looked at, one of which was trichloramine.
