Aqua-juraperle JW®

General
Aqua-juraperle JW is a granular filter medium with a purity of 99.1 % calcium carbonate. Because of its micro-crystalline structure, it is superior to ordinary limestone. Aqua-juraperle JW keeps its activity for pH-adjustment even after removal of high concentrations of iron and manganese.

Applications
Aqua- juraperle JW is commonly used for:

  • CO2-removal and remineralisation of soft water,
  • remineralisation of distillate and/or R.O.-water,
  • removal of iron and manganese as well as aluminium.
