PO->LOX->O can be made as fast as you want it but if you're not using the glitch it's insanely power hungry. Assuming use of hamster wheels, a dupe has hard time to make enough energy to generate oxygen he consumes.

Even with the glitch, PO->LOX->O requires a large and complex machine while electrolyzer is just a simple device.

I know.  I've made them in my base

You need a very large production of PO, which can only be sustained by having lots of Morbs.  If PO is generated through polluted water, you will have issues collecting enough of it due to the sublimation rate.  You would need a large surface area which will have issues with mass flow.

The polluted water will let out polluted O2, and polluted O2 could be cooled down to liquid O2 and then change to clean O2

Polluted water does not just emit polluted O2.  It converts clean O2 to polluted. So, this cycle does nothing.  You can verify this by putting some polluted water in a closed container with either a vacuum or any gas other than O2.  No new O2 will appear in the container.

For the polluted water, I've tested something about making O2 from it

Which every step is 1:1 on mass, so this maybe the way that cost least to make O2...

Hah, dat is lots of energy... And also, it takes very very long time and space to turn polluted water into PO² I may not say correct numbers, but it something like 0.5 kg/cycle per tile. For that purposes better use morbs (which can be duplicated using dupe corpses), about 12 kg/cycle.

How's that going to work?  I thought the liquid vent for clean water don't work when submerged.

Dirty water is moved to the tile with dirty water when clean water is vented in. Then clean water is contaminated.

Yes, this system will give you additional 12% O² if compare it to electrolyzers, but lmao there no space to build such systems, just imagine, you have 60 dupes with diver's lungs (which is also insane). Even with compact setup 1x2 you will need about 2700 PO² per cycle, which means something like 5400 raw water tiles or 10800 farm tiles 108x106 with borders and vent shaft:

Not small, yeah? And also... it will cost you dozens of raw metal something like 500k (if there is a way to find such amount, huh)

It emits polluted O² if there is a block of O² or PO² above it.

According to my testing, it does both.  Polluted water will transform into PO if there is some O as catalyst.  The mass converted is more than the O input.  There is a very very small mass loss for O.  Once this the transformation started, the PO will also serve as catalyst such that over time more and more polluted water will transform into PO.  The mass loss for polluted water is very small but noticeable over periods of say a dozen cycles.  The transformation does pause if there are more than 5kg of PO above the polluted water.

The best thing to do is to add some pufts to this system.  They wander all over the room and will suck up PO as it is being created.  The slimes dropped can be recovered and stored in storage containers and allowed to sublimate in another room.  The sublimation rate here is better controlled and can be packed better than liquid.

Acturally, I've tested it

Dirty water itself becomes polluted O2
