Water is one of the most important substances on Earth, covering 71% of the Earth's surface, while the human body can contain up to 75% of water. Water is essential for a wide range of applications, including agriculture, science, medicine, transportation, heating, recreation, and food processing, as well as cleaning, and perhaps most importantly: drinking. Many common water problems can be solved by water purification systems. Laboratory ultrapure water equipment currently sold by ATO provides the highest quality pure and ultrapure water with multi-stage pre-filters, reverse osmosis(RO), ultrafiltration(UF), ion exchange, UV, final filters, and other technologies. In this blog, the ATO will take you through what a water purification system is and how it works.
