Thanks

Most acid scrubbers - and I assume you are scrubbing acids - use sodium hydroxide and try to maintain a pH >12, usually a concentration of >8% NaOH is recommended. Some scrubbers also use sodium sulfide.

I have not run across anyone using soda ash, I think maybe because the pH of a soda ash solution is too low.

I'm a cheap skate, I use limestone gravel mixed with lime water and soda ash. The limestone renews the soda's strength.
I sieve off the small rocks to leave the stones with plenty of porosity lest they harden like cement. The limestone makes up 99% of the alkali. The end product is calcium chloride, great for de-icing and keeping the EPA off my back. :lol: Dr. Poe
