Bore water contaminants are mainly mineral salts however ground water contamination may also create organic chemical issues.

Mineral salt treatments may include coarse filtration, 5 micron filtration, desalination by reverse osmosis, pH adjustment and disinfection.

Excessive levels of iron may sometimes be the primary concern. Generally, biological pathogens are low but this can be determined with laboratory testing.

Iron can present a special challenge for water treatment as ground water iron is usually clear until it is exposed to air. Contact with air over several hours will cause the clear, ferrous iron to change to a reddish brown ferric iron through the process of oxidisation.

Ferric iron coagulates into small particles and fouls most water treatment systems. Water treatment for iron involves accelerated oxidation before settling or media filtration.

Vertex Hydropore have a variety of technologies to use in the case of bore water treatment including;

  • Oxidation, in the case of iron, involving aeration, chlorine and chlorine dioxide
  • Coarse filtration or backwashing multimedia filtration and additionally bag filter or cartridge filter
  • Fine filtration with 1 micron cartridge filter
  • Mineral salt reduction that will reverse osmosis @ 15 to 25 Bar
  • pH adjustment with a sodium hydroxide injection or calcite filter
  • Disinfection using chlorine, ozone, ultraviolet irradiation
