Chlorine is the most validated and used solution for water disinfection worldwide, because it is effective and guarantees a residual effect preventing microorganism growth in the water body before usage. Nevertheless, when organic compounds are contained in the treated water, potentially carcinogenic compounds can be formed. In order to prevent the risk of hazardous by-product formation, alternative disinfection technologies can be applied, e.g. based on ozone or advanced oxidants. Our solutions includes:

  • Capital Controls Gas Feed Disinfection
  • Capital Controls, ADVANCE, MicroChem Instrumentation
