Water treatment is a process that makes water more acceptable for a desired end-use. These can include use for drinking water, industrial processes, medical, and many other uses. The goal of all water treatment process is to remove existing contaminants in the water, improving it for subsequent use. There are many treatment processes for water, depending upon its application. Pharmaceutical and laboratory water usually requires ultra-pure water with extremely low levels of dissolved gases and other contaminants. Treatment, using degasification and decarbonation equipment, increases the life of process equipment by preventing or controlling corrosion.
