Hello folks,
I've done a bit of searching and wasn't able to find any good answer to this question.
We're designing a 50% caustic feed system for a water treatment plant in north Texas. Design flow is 50 GPH. The chemical skid will be outdoors and I believe completely exposed to the elements.
Questions are:
1) What temperature should we maintain in the chemical storage tank? I've read numerous sources that say to target 80*F but our lead engineer wants to go with 65*F. I've looked at the viscosity difference between the two temperatures which shows 80 cP vs. ~50 cP for 80*F and 65*F. Is there any additional rationale for the higher temperature? We're above the freezing point (54*F).
2) We are planning on using CPVC piping for the feed lines on this skid, 1" and 3/4". Is this a wise choice for a skid that is outdoors and unprotected? I know CPVC has a higher chemical resistance but can be rather brittle from my experience with continued UV exposure.
Thanks in advance for the help guys!
