How to maintain the pH of water in industry?

In our industries the water is acidic so we want to maintain the water pH to save our equipment. Because of this water the equipment where we are using this water is getting punctured so we have to maintain the pH of the water.
We are requesting you please suggest to us "How to maintain the pH of this water".

Look at using RO water vs. tap water.
You can treat the water, but the added salts will tend to clog the water passages in the hottest areas. If there is no copper, you might try using ammonium hydroxide and raise the pH to about 6 and no higher than 8. This can be automated.
