Purified water

Purified water is water from any basis that is physically processed to take away impurities. Distilled water and deionized water have been majority general forms of purified water, but water can also be purified by other processes including reverse osmosis, carbon filtration, micro porous filtration, ultra filtration, ultraviolet oxidation, or electron dialysis. In recent decades, a combination of the above processes have come into apply to generate water of such high purity that its sketch contaminants are measured in parts per billion or parts per trillion. Purified water has many uses, largely in science and engineering laboratories and industries, and is produced in a range of purities.
