Pre-1.0 I had aluminum factories that took the waste water from aluminum scrap and fed it back to the alumina solution refineries. However, in my new 1.0 world I can’t seem to get it to flow correctly.

I’ve tried several solutions, including:

  • putting the waste water lower in the junction than the fresh water
  • adding a valve to the waste water to prevent backflow
  • adding a valve to the waste water to only supply the amount not provided by the fresh water

The only think I have not done yet is decrease the water extractor rates, mostly because I don’t recall having to do that before when I used a valve.

Any tips? Anyone else had success in 1.0

Update: I believe I may have found a solution - I’ve added a fluid buffer just after the waste and fresh water merge.

waste       fresh
    \      /
     buffer
        | 
     refinery

This seems to give the pipeline a little wiggle room to settle, whereas without the buffer the fresh water would slowly fill in whenever the waste water wasn’t at full production. The waste water would then back up, which meant production of aluminum scrap would back up, which meant that alumina solution would back up, and then meant the water would back up leading to a sort of deadlock With the buffer there’s a little more wiggle room in the pipeline for excess water

    To be honest, I usually dedicate some refineries to using waste water - the Satisfactory fluid mechanics are too janky and all the fluid logic gates you might see creators discuss are based on specifics of how fluid calculations are done which could be changed without warning (especially for things like putting a hump in a line - that relies on the engine not doing some specific optimizations).

    Having waste go into refineries that get priority on bauxite means you’ll need to pay a few minutes to build a buffer initially and then your output should be consistent as long as the refinery capacity and bauxite flow are sufficient.

        This is what I do, maybe not optimized to the best but if you looked at my factories they are not optimized but they will never clog because of by products.

        I tried using the waste yellow stuff (I’m not at a computer lol) from making uranium cells to process the nuclear by product but it kept getting clogged and I ended up setting up a package and sinking it for full reliability.

        This was all my first blind playthrough. I learned a lot but there is something to be said for reliability

        Oh, my suggestion is just to have some of your aluminum factories use waste water exclusively… then it’s impossible to have a backup.
