Wastewater Issues with Saponifiers

#26276

Wastewater Issues with Saponifiers | 5 November, 2003

Although the supplier of our saponifier claims their product is safe to go down the drain, our local wastewater code will not allow affluent with a pH >9.0. In it's spent form (from a batch cleaner) the cleaning solution is at a pH of 10.1.

Luckily, we are setup with a holding tank and have an oppurtunity to treat the stuff before sending to drain. My question is, what is the easiest way to adjust pH without spending serious $$?

I would like to hear from folks with direct experience.

Thanks.

Consider adding measured amounts of muriatic acid to the holding tank. Muriatic acid is used as a pH reducer and is available at pool supply stores. An alternative to muriatic acid is granular sodium bisulfate, also available at some pool supply stores.

Add some orange juice! Seriously, with a high PH adding almost any form of acidic soluble material will bring it down
