Tertiary treatment

Tertiary treatment separates the floating and colloidal substances that may remain after the primary or secondary treatment. AQUA Industrial Watertreatment provides a few techniques to remove the remaining dirt.

  1. Curieau®
  2. Precipitation
    During precipitation, dissolved inorganic substances precipitate with the help of chemical reactions. This is a useful process to for example, extract phosphates and sulphides from the water by using Ferric and/or aluminium.
  3. Oxidation
    Pollutants which are difficult to degrade can be converted by strong oxidants into an easily degradable or extractable substance.
  4. Adsorption
    Certain pollutants can be extracted by adsorption with activated carbon.
  5. Ion replacement
    Harmful ions that are difficult  to remove will be replaced by harmless ions. The ion exchanger will become saturated after a period. After cleaning, a concentrated solution of harmful ions remains.
  6. Desinfection
    Viruses and bacteria can be eliminated or inactivated by oxidation or radiation with UV light.
  7. Bleaching
    The technique of bleaching is often part of the primary or secondary treatment. Depending on the die or vcolorant, AQUA Industrial Watertreatment applies one of the afore mentioned techniques.
