Aqua-juraperle TWA / Limestone, Calcium carbonate, Marble
Aqua-juraperle TWA 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 TWA keeps its activity for pH-adjustment even after removal of high concentrations of iron and manganese.
Applications
Aqua- juraperle TWA 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.
