Scale removal

++

Hi all,

This question is related to Scale removal. Please tell why we have scale around the tubing in the well. How can we remove this thing by chemical?

Thanks a lot,

I find your question a bit vague, Phan, but do you mean that you have scale from water hardness? Water contains dissolved impurities; when the water evaporates the impurities stay behind and build up. Any mild acid, even vinegar if you're patient enough, can remove that kind of scale.

I totally agree with what Ted had said. Water Impurity and Hardness is usually the major incentive which causes the scale in the water system. Incorporating the mild acids into the water is the good approach to work out this problem ,particularly the water hardness. Ted's put is absolutely right. Herein what i wanna say more is the acid's choice. I have no idea of what's ur well used for. what is the right acid i supposed to be selected is the organic acid with the good chelating power like the monohydroxy acid. if you are going to remove the scale , i suggest you may try the glycolic acid( hydroxy acetic acid). after the removal, adding a little glycolic acid into the well water can prevent effectivelly the scale, you may try it.

Good luck!
