How to filter multiple fluids at once

[ICKA]

So I saw this video from Brothgar and decided try my own take at a zero energy liquid filter. I was just hoping to make one that could be 2x2 but I ended up making a system that can separate many fluids at once. So far I've tested up to four, some screenshots below.

 

Polluted water, crude oil, petroleum, and clean water kept separate in different tanks. The blob at the bottom is a mixture of the four liquids, arranged by density.

Breaking open each tank at the same time.

All the liquids are now nice and separated!

So to make this you need to have the center blob arranged by density, as mentioned earlier. Each liquid layer needs 3 tile spaces to rest on, two from the liquid layer below it, and one being a regular tile or airflow tile. If the tile is between liquids it should be made out of airflow tiles in order to prevent gas bubbles from stopping the flow. This is also possible to do 3 wide if needed. I am not sure if it would work with the center blob only being one tile space wide.

To make this in survival mode you should only need a single bottle emptier and simply drop enough fluid for each layer to flow one tile space in to their respective tanks, starting with the most dense fluid and ending with the least. This should seal off each tank and prevent other fluids from entering.

If you flood the center with a large amount of a single fluid, the blob will disappear, however it will still filter to each tank fine. After enough time has passed for the liquid to filter the blob will start to reform.

This is my first time posting here and I've been loving the game so far! Hope this helps anyone who needs it!

This is interesting use more space but 0 energy

[Saturnus]

Mind you. You can also do it with liquid mechanical filters. Likewise zero energy use but a lot more useful as it's done with liquid in pipes.

[ICKA]

Yeah, one of the reasons I made this was because the liquid filter actually produces a significant amount of heat (I think 20 W). It's also useful that this can filter many fluids at once.

Edit: I realized later you were talking about this 

I think I'll try this out later, although in a lot of the experiments I was running I needed one liquid to be dropped in a nearby tank and the other to go to a farther location.

An improvement I found for the mechanical filter is to place 2 bridges on the main pipe; have a valve in the 2x1 space between the outputs and the inputs (doesn't matter which direction); set the valve to 0.1gr; connect the outputs and the filter input and output (no pipe between the filter input/output); this method will send the first gas/liquid the system encounters through the valve output, and rest of gases/liquids down the main pipe and also deal with full packets

That is in the original thread as well.

My suggestion is an improvement over Kasuha's as it is more compact and has less pipe in the mechanism - so it is less often confused during the priming stage (if being done without a temporary priming valve)

Maybe provide a picture like those in the original thread so we can see what the difference is, and why it should be an improvement. As you explained it sounds to be exactly the same, maybe with the filter turned 90 degrees to save space like most build it in game.

Just to illustrate. This is how most would build the @Kasuha filter in a practical build. His drawing is stretched it out for clarity as it would otherwise be difficult to see exactly what is going on. (Save file below).

This filter all 6 naturally occurring gases in the game. Technically there's a 7th; steam; but if you have that in your gas pipe system you have bigger problems than needing to sort gases.

Thanks for this, was making much bigger version of this with 3 bridges to make sure nothing gets left out. These compact versions seem like they will do the job.

I use the mechanical filters fairly often except when the final output can become blocked, like when outputting to NGGs for example.

You guys have any tricks for these types of situations? I end up using regular filters.  I guess I could also pre-filter gases in separate tanks with high pressure vents, but then I need to use more pumps.

Wow, amazing. Watching the gasses go in circles indefinitely via the Gas Valves is like magic.

The filter I posted actually have an overflow tank at the end. The idea is that you put a sensor in it to turn on a remotely located blockage warning light and turn on the recirculation pump above a certain pressure level.

If one of your gas lines becomes blocked on a regular basis then you should make an overflow buffer tank. Here's how in the most compact space possible. Naturally you should adjust size to suit your needs.

The gas flows in at the red arrow. If the output is blocked, it overflows the bridge and vent out into the buffer. The pump immediately tries to clear the buffer but can only do so when both the buffer output and buffer input is cleared due to the output of the pump flows into the line via a bridge after the overflow bridge.

I use this type of buffer on my polluted water line all the time.

Thanks Saturnus, seems like a great trick indeed!  I don't see the overflow tank in the save file though.

I think I get most of what you are explaining except for the part about a sensor turning on a warning light?  This is all automated right, it's not just turning a light so that the player knows he has to do something?

It's all automated. I didn't connect it up in the save but the overflow buffer is the bottom room at the end of all the filters. The function is simple, it catches gases that for some reason did not get filtered. Usually because one of the outputs are blocked. Just put an at atmo-sensor in the rrom and connect it to the pump... and alternatively to a warning light. The logic is that if enough gas has overflown the filters, it might be a good idea to see why, and then recirculate the gases through the filter to retry filtering them.

ah ok thanks, didn't recognize it without the bridges.

That's because the filter overflow buffer serves a different purpose than the in-line overflow buffer with the bridges. The in-line overflow buffer can serve several different purposes depending on what you use it for.

Fascinating, I'd just seen the gas filter topic a long while back, I'd started trying to use it on water, realized the pipe shouldn't be running through. (Took me a while.)

A few days ago I discovered I could use the overflow buffer chamber for a different application, to evenly distribute gasses with a top down priority with a single gas line. Depending on the length, throughput, consumption, size of area, it can take a bit for the packets to back up in the gas line top down, but it sure is efficient for my purposes of evenly distributing oxygen without bursting my dupes ear drums. (SAD) Turned my entire base into the overflow chamber.

I noticed recently, unless I'm oblivious, that gasses now are in grams in terms of safety, kg not good for dupe ears. IMO terrible for debug gas value input typing, it dispenses in kg..
