Polluted Oxygen

[thejohn1567]

Now that pufts got the buff they needed, what are good ways to get polluted oxygen? Is a wide polluted water pool going to off gas enough or is it better to bottle everything up?

Also is polluted dirt off gassing worth it?

The volume of Polluted O2 created is relative to the volume of the source, whether it be Polluted Water, Polluted Dirt, or Slime.  So generally Polluted Water is the best source, since it has the highest per-tile mass.

The easiest way to manufacture large quantities of Polluted O2 from Polluted Water is to build a "comb" shaped structure out of Airflow Tiles, and fill it with Polluted Water.  The larger the "comb", the larger the bubbles of Polluted O2 it will make, since it counts the entire volume of the pool, not just the surface tiles where it will emerge.  However, the interval at which the bubble will off-gas is determined at random, and as such is not a constant (or even predictable) manner.

This is where Bottled Polluted Water comes in.  Bottled Polluted Water will off-gas dramatically faster than a pool will.  The drawback is that it is usually a hefty amount of legwork to set up a system to generate lots of bottles of Polluted Water.  But as has been demonstrated, there are several builds that can be used to facilitate that, the least of which is to simply use Algae Terrariums and not collect the bottles of Polluted Water they produce.  Let them off-gas in place.  There are a few builds that use automation to force Dupes to drop bottles into a pit, as well.

Thanks, I might try dripping water into a shallow pool and having my least favorite dupe mop it eternally.

You should have your favourite dupes do it instead, because they are gonna level up strength like crazy =v Being locked whole cycles inside the putrid gym is a small price to pay for such a blessing.

Morbs.

Will feed both pufts and dense pufts.

A full tile of PW produces 2.4 kg of polluted o2 per cycle. That’s 21 full tiles per new puft. Not so bad. Keeping the tiles full can be tricky. The comb structure is best. The basic idea is you want a one tile high space filled with PW and topped with an airflow tile.

250 of these can feed a full PO2 gas line.

And this is why I use bottled polluted water... 

Or at least overpressure the polluted water in the airflow tile offgasser.

just dont collect the pWater from Algae terrarium, and sooner than enough your base will be over pressured. Of course this is only valid in map with access to Algae, otherwise you can set up a wide array of tile and drip the pwater then mop it and let it be there. 

I personally never bother with such setup since most of the time, by the time i am accessing any biome with pool of pwater, the amount of pO2 is just way to much and enough for me to survive out of it for as long as I can remember.

Polluted water off gasses if left in bottles much faster than if on the floor.  So there are some easy solutions to get that. 

Terrariums.  Drip clean water on them and feed algae via sweeper arms.  One dupe can come empty them when full and you can either leave the bottles or use doors to push them where needed.  More or less automatable but requires dupe interaction every once in a while.

Empty pipe command.  You need on dupe who has the plumbing skill.  Feed polluted water through a pipe and end it with a bridge or something so water continues to flow.  Use 1 empty pipe command at the end and the dupe will continuously empty that pipe.  Since the pipe keeps refilling due to the water flow though, it's an endless task.  Stop him or stop water flow when the desired output is reached.  Semi automatable but requires a dupe interaction constantly and for you to re-label the pipe every time.

Continuous mopping.  Similar to above.  Drip water on a surface and send a dupe to mop it.  With the right flow they will do this forever.  Dupes get stressed from wet feet though.

Liquid storage containers.  Similar to above, fill a liquid reservior full of polluted water then deconstruct it.  Now you are left with a 5t bottle of polluted water in the floor.  Repeat as necessary.  Not really automatable.  You have to build and destroy the reservoir every time but produces results much quicker.

 

I haven't tested this to know for certain, but it appears like polluted water also off gasses when exiting a liquid vent.  So if you have the power to sustain it, you could try to continuously use pumps to suck up water and drip it above.  Unsure if this works but there is an animination of it giving off polluted oxygen sometimes so possibly.

Additionally, compost piles emit polluted oxygen and algae distillers used to (not sure if they do now) and sieves output polluted dirt that off gasses as well so you could gather these into a room to siphon off some from them.

Morbs work too but I'm unsure how efficient they are for this task.

Just tested this by dripping polluted water from the top of a completely vacuumed map.  It only offgasses once it hits the ground.

Wouldn't this mess up the offgassing of the bottles since they would be considered to be in a water tile?

I set up an auto door drop system and it worked wonderfully well, but if it got a water spill on it then the system broke.

Yes, if you get water on the polluted water bottles, they stop off gassing.  However, you can use this to your advantage and move the bottles where you want them via door conveyors and use the oxygen produced for dupes or atmosuits or LOX.

What I recommend doing is set your terrariums on top of horizontal doors.  Open the doors after the terrariums have been emptied so that the bottles drop down and the water goes with them.  Another set of horizontal doors 1 tile below the previous ones catches the bottles and water while preventing the oxygen from leaving the above room or any contaminates for entering.  Close the upper level of doors, the open the bottom layer of doors to deposit the polluted bottles into your puft farm.  If you make the bottom of your puft ranch out of mesh tiles, the water will drop down and can be recollected at the bottom to be pumped back up to the terrariums.

@Neotuck made a post on this a while ago and I over automated it on page 3 of that post if you are interested.  The automation could probably be refined but up until now it wasn't worth ranching pufts so I never worried about it.  Instead of having the puft room below your terrariums you could put it to the side and push all the bottles into an area that dupes can't access to ensure they don't sweep up the bottles accidentally and so you don't have to micro manage door access.

Here is also a post of his base oxygen setup if you want to use it in a base vs for pufts.
