With "Add acids to ore refining and mining of infinite ores" OFF, Water Treatment 2 technology no longer unlocks purification recipes for chloric, fluoric, and nitric waste waters. Only sww purification is available:
However all four waste waters are still in use and can be both produced and consumed by other recipes.
This feels off, but might be intended.
In this configuration, sodium nitrate cannot be made, but two recipes use it as an ingredient:
I see several ways to fix this:
purification recipes should always be available when the waste waters can be produced,
all recipes involving sodium nitrate should be hidden
force use of acids for mining and refining, maybe only if Bioprocessing or Industries is loaded
