Possible to clean slime without getting infected?


Recommended Posts

Is it possible to clean slime without getting infected?
I struggle some time to clean a relatively tiny area of slime lung without getting infected. So far I had no success and I really wonder if it is possible to swipe slimelung-slime completely without getting sick.

So far I tried:  

1. WATER + Chlorine
I left 1 row of water on the ground, so that all infected slime dropped right in the water without emitting pO2. Leaving the slime behind is not an option here.
So I placed a locker in chlorine atmosphere 1 tile away: However as soon as my dups remove the slime (touch it), they get sick.

2. CHLORINE
I filled the room completely with chlorine and continued to pump chlorine in. Any potential O2 is pumped out. Additionally I spammed the ground with deodorizers. As soon as infected debris falls in the chlorine the gems wear off. However on slime it doesn’t as the slime continues to produce enough PO2 to keep the chlorine away. What I get in the end is infected O2. Great ;)

3. COLD WATER
I tried to fill the row of 10x1 tiles with cold water (target -5°C). However the logistic setup went totally off limits and the Thermo Aquatuner broke several times. When submerged elsewhere it took ages and the pipes broke meanwhile.  So it did not prove feasible to implement on large scale.

Do you have any solutions how to clean slime away without being infected?
Or how to cool down water easily and efficient?

Use ore scrubbers between harvest position and storage locker.
Watch (overlay) how your storage lockers get infected. Don't use that material inside your base to build stuff, while it's germy.
Store slime in storage lockers, 1/4 deep in clean water (no pollution)
Cooling

Define sick?

Your handlers/dupes have to fall below to 0 immunity before they actually contract the slimelung in its full form. 

Venture to the purple biome and get some bleachstone. The hand sanitizer will remove germs ...they can pass by while carrying the slime and reduce the germ burden... occasionally they can carry germy stuff after doing so without getting any more germs.

well, with sick I meant actually contaminated. Sorry.

It's true that they are not directly diseased. However as germ hosts they start spreading the germs everywhere in my base. 
I want to prevent that they bring them back in.
I did not use  sanitizer  yet,  but I assume that they will only remove surface germs, right?  

And as I understood it: as soon as my dups breathe pO2 emitted from the slime they will get the slimelung...

So the question would be, is it possible to clean slime without being contaminated?

 

 

My preferred way is to use wheezeworts to push the infection away from the digging surface. It's not lightning fast but it works. The only problem are chambers filled with infected polluted oxygen or if there are blobs of slime produced by pufts, then you need to deal with the airborne infection - possibly again by freezing the oxygen (and waiting till germs die out) or using deodorizers and waiting till germs die in clay. Storing it in cold place again helps. Dug slime needs to be stored in cold place, then it'll stop outgassing and the germs will eventually die as well.

For instance this area originally contained slime with about one million germs per tile. It's almost completely dug out without digging a single infected tile.

And here's my slime storage. No germs, no outgassing.

No, but surface germs can be solved with strategic gasses and placement of sanitizers, and ore scrubbers if needed.

A baseline duplicant has a immunity recovery rate or 15% per cycle - I think this translates to removal of 15% of internal germs per cycle... this is explained somewhere in the forums or game  ( not making this up but the number is fuzzy right now ) it's a direct correlation to internal germ kill rate none the less.

Surface germs spread, internal germs affect that particular dupe. Just catch your dupes before they fall below 50% and they should recover their immunity, you'll have to watch their stats, it should give more detailed information on the rate of change for that particular dupe.

They can be sent to the medbed on high priority if need be, this should distract them at least...

Things are a bit different in the oil upgrade in this regard.

You can set up a water delivery building and send a thin skim on clean water over polluted water to keep it from outgasssing ... some people drop slime into PW like this and store slime in polluted or clean warer until it needs to be run through a scrubbing line.

Minimizing or eliminating outgassing of slime is paramount if your working in heavy polluted O2.

What I mention here is mostly hot handling of infected slime. There are other passive ways to deal with it as mentioned by @Kasuha.

Thanks for the quick and comprehensive expansions,  @The Plum Gate. Understanding the spreading (surface vs host) will make it easier to tackle the gems!

Also the approach of @Kasuha looks really nice.  However in Cycle 61, whilst expanding the boundaries of my base...  I guess I will save that one for later ;)

You can expand through caustic biomes and leave slime for later. There's a lot of algae in caustic biomes and to dig the little gold amalgam you may need for your heat resistant machinery, snatching a few wheezeworts from the closest ice biome is sufficient.

If you can incorporate some cooled surface liquid - just a thin layer of it along with your wheezeworts, this becomes ridiculously easy.

Using cold temps was the first thing I tried to get rid of slimelung filled areas, and it's still the easiest early game method now. Have all of your storage in a chlorine filled room and you can forego the ore scrubber and just cleanse everything you sweep within minutes.

I just throw everything in there, an initial chlorine chamber, deoderizer, carbon skimmer, lots of ore scrubber, washbasin, and finally an overpressurized chlorine storage chamber. It's probably overkilling it, but I hate having even the tiniest bit of slimelung in my base.

Stay away from PO2 is main thing. As to your specific question,

1. Build a tank in ice biome, fill with PW (and if you want a small amount of water on top to stop PO2) (Below pic I had too much ice/snow melt in the tank causing it to over fill; no need for this much water)

2. Put in trash compactors covered with the PW.

I have one set for slime only (stops slime from making PO2 and kills off slimelung).  This one is set to 6 priority so slime is picked up to prevent PO2 generation in the dig out area.

Rest have all components in slime biome set to sweep (sandstone, gold, algae, etc).  Just sweep it up when you want to.  After a while, empty out the compactor and repeat. I just let the resources pill up on floor inside the tank.  Just don't have any compactors in your base set to those components (at least, when actively digging.  You can "transfer" them from the tank once all the slimelung is dead if you want; just make sure those base compactors are full to avoid mistake loading of slimelung there)

The cold (-5C) will quickly clean all contaminated ore,
