Distilled Water Treatment

Industrial distillation technologies that produce highly purified water.

Industrial distillation technologies that produce highly purified water.

Distillation uses a heat source to vaporise water and separate pure water molecules from contaminants with a higher boiling point. Here's how distilled water is made:

  • Water is heated until it boils and begins to evaporate
  • The water temperature is then kept at a constant
  • The stable temperature ensures continued water vaporisation, but prevents drinking water contaminants with a higher boiling point from evaporating
  • The evaporated water is then collected and sent through a tube system to another container
  • Finally, removed from the heat source, the steam condenses back into its original liquid form

Contaminants that have a higher boiling point than water stay in the original container. This process removes most minerals, bacteria and viruses, and any chemicals that have a higher boiling point than water, from the water.

Veolia Water Distillation Plant

Polaris is a range of high-capacity water distillation units producing water for injection and clean steam. Polaris systems are designed in accordance with strict worldwide regulations ensuring total compliance. Polaris can be beneficially combined with other packages to implement a complete high-purity water system, from source water through to high-purity water for injection and clean steam generation.

Water for Injection Specifications

Water for injection (WFI) is water that is intended for use in the manufacture of medicines where the solvent is water, or water that is used to dissolve or dilute substances or preparations for administration. Biopharmaceutical production methods often require large quantities of pharmaceutical-grade, ultra pure water. The microbiological, chemical and physical parameters that must be met are specified in the European Pharmacopoeia (Ph. Eur.) and elsewhere.
