Liquid reservoir gas exposure: bug or feature?


Recommended Posts

So I use liquid reservoirs to buffer my diseased polluted water. And by chance, this group of reservoirs happened to be in a place with lots of chlorine gas. (I built it in a part of the base where I hadn't yet tamed the atmosphere.)

And the chlorine very rapidly killed all the germs in the water, cheaply turning it into much-more-valuable "clean" PH2O.

This feels too easy. Is this the intended behavior or a bug?

Hmm... so is chlorine suddenly useful? :D

There are already some settings for purifying polluted water and oxygen using this feature. It does feel a bit strange, there is question however, if killing germs truly makes polluted water "much-more-valuable". You can use PH2O with germs for everything, even H20 with germs doesn't affect plants in any way. The only device you need germ-free water for is water cooler.

By the way, germs are so harmless right now (especially in the mid-game), that I'm wondering if there is even a need for a method to remove them from pretty much anything. Maybe slime, if you want to put mushroom farm inside the main base.

That's a separate topic

If food poisoning germs remains as harmless as it is now then it kinda makes the game feel unbalanced, I expect will have another "outbreak" update

another reason I believe this is there are other germs listed in debug mode that are not yet added to survival

How long does it take to decontaminate?

I think a simpler version of Neotuck's setup would just be if the tanks rotated outputs, with enough downtime on each tank to purify the water.

also if you sieve the water first

normal water decontaminates faster than PW

I don't know how to quantify it? But, plenty fast enough for my purposes. I daisy-chained four reservoirs in a room with mostly NG and a little chlorine sloshing around the bottom, and piped in the outflow from showers, sinks, toilets, and algae refineries. So long as at least one of the tanks was completely full, the germs were found only in the partially full tank nearest the input. Germ-free water flowed out the back.

I'm not sure how long it takes for all the germs to die, but to your second point, I do believe that's exactly how Neotuck's setup works.  As I've said, I use the modified version I posted.  Basically, one tank is always filling, one is decontaminating and one is draining.  The automation rotates these around every 200 seconds.  Also, decon tank allows the gas to rotate, otherwise the germs in the pipes don't die.  This setup allows 10Kg/s processing and the only flaw I've found is that it breaks when you load the game unless you add the germ sensor on the output, due to buffer/filters resetting on load.

edit: oops I didn't post in this thread, it was over here:

 

Gas/liquid reservoirs interact with the gasses they are surrounded in, but something to note is they also interact with the tiles they sit upon.

I recall someone making a LH2 setup with a gas reservoir of chilled hydrogen, and the method of preventing all thermal interaction was mesh tiles, because mesh tiles take on the properties of the gas/liquid they contain. Placing the mesh tile and reservoir in vacuum gave perfect insulation.

Germs use half-lives, it takes approx 120s to fully disinfect water in a reservoir. Shouldn't depend on the amount of water, but with this game everything's possible.

Have to incorporate the time it takes fresh germy PW to fill the tank 

It's true my build doesn't need the full 200s, the extra time is just to be sure all germs are dead before the tank empties

I'm talking the time after the input shutoff has been closed. The cycle is "input desired amount of water, close input shutoff, wait 120s, enable the reservoir's door".

A basic setup using a clock sensor as water counter disinfects 2400kg of water per cycle per reservoir in ideal conditions.

I'll run some tests on debug mode and get back to you
