Ozone (O3) is increasingly used to purify water as an alternative to chlorination. There are four principle applications:
Historically, chlorination has been the preferred large-scale method of sterilization of water. However, there are significant health and safety risks involved in the bulk transport and application of chlorination systems. Also, chlorine can produce harmful, carcinogenic by-products. For these reasons the implementation of ozone sterilizers has gathered pace in recent years.
There are three main reasons to measure the moisture content of the feed air or oxygen in this process: Prevent arcing in the generator electrodes, prevent corrosion of system components due to nitric acid formation and Increase ozonation efficiency. If a high moisture level exists in the feed gas, arcing of the electrodes and, in extreme cases contact breakover to chamber walls, will occur. This arcing will damage the electrodes and the system walls and eventually lead to failure and expensive repair.
