The system 4 provides complete automation of the water disinfection process and chemical
treatment with unique capabilities for a “Hands Free” operation, allowing for true automation 24
hours a day. It works with any oxidizer such as Chlorine, Chlorine Dioxide, Bromine, Ozone,
Peroxide, or Peroxyacetic Acid. It also controls the pH with any process compatible acid such as
Citric, Phosphoric, Muratic or Sulfuric Acid.
