Hi All,
So in section 4.5 it lists the groups of chemicals considered harmful to concrete. There is a note for group 3 that "the concentrations shown are weight percent, and are the typical maximum concentration of the chemical delivered and used at the facility."
So, I'm doing a clarifier that has some pretty bad chemicals in it (not your typical wastewaster). They are adding some ferrous chloride at 45% concentrations to help treat this stuff. However, they aren't storing that in the tank, they're just adding it to it. So the question is, is the intent of the statement the applied concentration, or the resultant concentration? IE, if I take 45% concentration and add it to a clarifier tank, it's a small, small percentage at that point. But, if it's the application that it's referring to, it seems like I need a protective lining.
I won't spoil your answers with my interpretation quite yet.
If I need a protective lining, any proprietary recommendations are welcome.
Thanks!
