Reverse Osmosis (RO) Filtration (w/ Matt Mueller)

What we're doing is we're taking the water in the pool.

We're running it through an extremely fine...

You could think of it as a filtration.

It's not exactly correct to think of that because it's actually like molecular transfer through a membrane.

So it's...

Your pool filter is... particulate filtration.

So it's going to filter things that are large.

You can think of reverse osmosis as a filter for total dissolved solids.

So things that actually get dissolved into the solution of the water, like your TDS, your calcium, phosphates.

CYA, phosphates.

Yeah, CYA, exactly.

And those are the main four that I look at because those are the problem childs that you can't really deal with as effectively.

So that's our main focus.

Well,

hold on, hold on, hold on, hold on.

Those may be the main four that you look at, but- There are big problems that can accumulate.

I'm thinking things like nitrates that most people don't test for.

Nitrates are a pain.

That's food for algae and there's no other way to get rid of them because that's its final oxidation state for nitrogen.

So they're in there just like phosphates.

Chlorine doesn't interact with them either.

So nitrates, sulfates, then you have other nitrogen compounds.

Can it remove combined chlorine? I would imagine it could.

Yeah.

Yeah, it can.
