angel+bob struggling to void purified water

[wheezil]

I'm using angel+bob mod pack, and I've checked the option "do not hide void recipes", but I'm just not finding the void recipe, or what to machinery to use. In the crafting menu, searching for "void" comes up empty. FNEI also comes up empty for "void". I got here because I'm trying to make chemical science, which needs sodium hydroxide, which I can make from saline water, which comes from hyrdo plant. But how to get rid of the purified water for which I have no use?
Thanks

In angels clarifier is used to void fluids.
And recipes are hidden to not spam the list.
