Cooling Water Treatment Food Grade?

Has anyone successfully used food grade chemicals to treat cooling tower water. If not what controls have you put in place such as maintenance training, increase PM frequency, pressure differentials, etc.

Dear John,

Welcome to the forum !

I think there is an older thread on this topic on the forum. May be worth your doing a little searching.

Hi. Since you are located in the US, ZEP has a product called Peroxy Serve that works well for cooling water/direct container contact. I have attached their specification sheet for your information. Thank you.

Dear Ted,

I suspect the poster was looking for chemicals to treat the cooling water itself (eg biocides perhaps??) rather than the product/environment but I might be wrong.

I presume the same type of "guarantee" would be required as mentioned in yr attachment. The same kind of problem arises with lubricants, wall paints etc etc.

Thks anyway
