Boiling water vs purifying it

[TheEvilMango]

What r the benefits of boiling PW into steam and than condensing it back into water over just using the water purifier?

[Kabrute]

using the purifier wrong can cook your base and needs a steady supply of sand while using a pw boiler needs a regular supply of heat......

[0xFADE]

You get dirt from it too.  you also get to cool another liquid off with the aquatuner(s) and boil the polluted water as a free side effect.

The only real con is that it uses more power.

[ButterStuffed]

Boiling polluted water produces dirt.

@Kabrute can you elaborate a bit more into detail on why, it has to do with the change in thermal capacity doesn’t it?

[Kabrute]

the purifier takes in any temp pwater and converts it to 40c water, that is always a loss in thermal energy from the pwaters perspective but that 40c then usually goes running to the toilets and plants jacking the real heat up.

I've been using abyssalite pipes and havn't had any heating up from toilets/sinks.  Have not tried plants in awhile.  Pretty sure the box heats up.

The Toilet and Sink themselves will hold a quantity of the warm water, and since they are made from metals they will not only themselves become hot, but will radiate that heat to the area around them.  Fortunately the internal reservoir of these buildings is on the small side, so it's not a short term problem and you can usually counter it with an adequate air conditioner.  But it's a reasonably large loss in efficiency overall which will cost you power or other resources elsewhere.

Yeah I thought so too, maybe it is a bug.  I've had very hot geyser water going through all my toilets/sinks and it only stifled some of my mushrooms in one spot because I didn't use abyssalite pipes there.  It has all been fine now after fixing that mistake.  Anyway even if there is heat bleeding out it is insignificant enough to ignore.

While we r on the subject of boiling water. Ik that the best way is to use a aquatuner. IIRC the aquatuner out puts heat based on the heat of the water it is cooling. Is this correct? If it is would it be best to preheat water than pipe it through the aquaturner?

[Kabrute]

preheat the water before running it through a co2 scrubber, the only point in "preheating" your water is if you are preparing to send 15c or cooler water towards the tuner...... preheat that first, otherwise a tuner removes 14c heat from its contents, converts that to joules then dumps that heat into itself and surroundings at 99% efficiency. ::creates a negligible amount of cold over time in closed systems under every condition applicable::  As such only keeping your water from freezing on exiting the tuner is the only major consideration for the water being fed into it..... in my opinion

[SkunkMaster]

If you boil water you can potentially remove 1/3 of the heat in the pwater.

If you purify it you can remove up to 2/3 of the heat in the pwater. 

 

If you boil it you get dirt out.

if you purify you use sand. 

 

If you boil it you can use the aquatuners to cool other things.

If you purify you can use the polluted dirt and make fertilizer out of it.

 

Both have pros and cons, and i think both should be used, instead of just either one.

Let´s say you run ~ 123C (396K) Water to both system:

- The boiler will always remove 1/3 of the total heat (equivalent to 132 K)

-The water sieve will just remove 82-85 K (in a best case scenario)

no the water sieve will always put out the water at 40c, so you remove 83c if the water is 123c, so actually more then 2/3...

 

But you're right, the math from my side is simplified, the sieve removes way more heat if you consider mater change. 

 

[Lilalaunekuh]

Ok, seems we got a bit different view on energy here:

Let´s say we use polluted water at 396K(123C) and use the water sieve. It will remove 83K, so you got 313K(40C) water.

=> ~ 47% of total energy lost

 

If you run a boiler you will always convert max temperature polluted water into steam.

=> ~33% of total energy lost

but the sieve not only puts out the pwater at 40c, it also changes it into clean water. Are you taking that into consideration ?

My math:

1g of pwater at 123c = 738J

1g of water at 40c = 167,16j /// Wrong

 

1g of pwater at 123c (396,15k) = 2376,9J

1g of water at 40c (313,15K) = 1308,7J

 

That removes 1068.25J for each gram of pwater turned inside a sieve.

 

If you boil pwater into water 

 

1g of pwater at 123c (396,15k) = 2376,9J

1g of water at 123c (396,15k) = 1655,5J

so you remove in total 721,4J with each gram of pwater that you boil.

 

738 / 167,16 = 4,415 or in other words the pwater holds more then 4 times the thermal energy. And therefor it's more then 2/3 and actually just above 3/4 of the thermal energy that the sieve removes.

 

If you want specifics: The sieve removes a grand total of 77.35% of the thermal energy.

 

So the sieve removes close to 2x the thermal energy available in the pwater, compared to boiling

Nobody finds it worth mentioning the sieve does not removes germs, while boiling does? No?

Does anyone have a few screen shots of what they do to boil polluted water? I assume most people use aqua tuners so they can cool other liquids?

not "other liquids" but the clean water after condensing, no one want's 90c+ water in their base

Well, it really does depend.

 

90c water is fine for showers and such. 

 

But some of the water for plants and such has to be cooled. I find it more efficient to use sieves for plants and cool the sieved water, then to cool boiled water.

Use the boiled water for showers etc and let the cycle rotate there. And ofc boilers give of free dirt also

I find myself linking @Saturnus's 10kg/s distiller build all over.

Built before Automation, so it can probably be redesigned again to make use of Metal Tiles, Tempshift Plates, and Refined Metals in general for more efficiency.  The initial version in the thread ouputs clean water at 58 C, no indication if that changes to the improved model down the page.
