This is a plastic substrate that replaces the traditional mineral substrates and river substrates. They have several advantages:

This is a plastic substrate that replaces the traditional mineral substrates and river substrates. They have several advantages:

  • Large useful surface area in relation to the volume, enabling the biomass to fix itself to it.
  • Large free volume: perfect effluent circulation across the biological bed.
  • Its free layout follows several planes in different directions: first, it ensures homogeneous contact, avoiding preferential paths and, second, it increases stay time.
  • Irregular, rough surface: higher contact time between the two phases.
  • Biofilm thickness: self-adjustable by means of the anaerobic part inside it.
