Aqua-mandix / Manganese dioxide

Aqua-mandix is a natural, crushed manganese dioxide without additives and free from contamination. Used as a joker for catalytic removal of dissolved iron and manganese in one filtration step. The product will do a very good job already at pH 6,5 and even in presence of NH4. Aqua-mandix will also remove “parts of” As, Al and H2S if present next to Fe and Mn.

Applications:

Filtermedia for catalytic removal of dissolved iron and manganese with the following advantages:

  • passes its activity on to the surrounding sand grains,
  • does not require ideal pH environment,
  • does not require regeneration by KMnO4.
  • works even in presence of NH4
  • will also remove “parts of” As, Al and H2S
