Possible off-topic question about using Ro/di waste water in manufacturing

creas · Jul 21, 2017

I have a question about using RO/DI wastewater. One of the products my company manufacturers is a line of alkaline industrial cleaners that are water-based. It is made in a 1200 gallon tank where I have my waste water line connected. Do you think there would be any adverse effects from using water (maybe 200 gals out of 800 gal total water) with much higher concentrations of minerals/dissolved solids from the waste line? In the formula are basic soaps, detergents, surfactants and sodium hydroxide.

The waste line should only be about 25% higher in dissolved materials than untreated water. Unless your water is really bad to begin with, I wouldn't think it a concern.
