  • Humidification – dehumidification

OVERALL OPERATION

Biorings are hollow tubes of plastic or metal fitted with rings on which bacteria can attach. They have a considerable specific surface area (approx. 200 m2 / m3) as well as maximum free space and guarantee permanent flow because they do not clog up. The biorings are quite light, very easy to maintain and are often used in the final filter chamber. Biorings are also widely used in trickle filters.

RANDOM PACKING

Filtermat’s Plastic Random Packing is specially designed for biological wastewater treatment.

APPLICATIONS

  • BOD reduction
  • Nitrification process, including fish farming
  • Polishing
  • Biological wastewater treatment
  • Aerobic or anaerobic treatment of wastewater with high concentrations

HIGH CAPACITY AND EFFICIENCY

Two sizes (ETEP120 and ETEP210) allow for optimization of capacity and efficiency based on application requirements.

HIGH MECHANICAL STRENGTH AND UV PROTECTION

High mechanical strength provides excellent performance in deep beds.
The construction material is UV stabilized and chemically inert, making it non-toxic to microorganisms and immune to fungal or bacterial decomposition.
