Filtralite egner seg godt til vannrensing, enten det er drikkevann, avløpsvann eller forbehandling før avsaltning. Filtralite 0,8-1,6 med mer brukes i det nedre laget i det patenterte MonoMulti® filteret. Høy densitet og knuste leireaggregater.

  • Enkel å installere i filtre
  • Stor overflate for bakterier å vokse på
  • Effektiv partikkelfiltrering
