Biological Trickling Filter

Sander’s Biological Trickling Filters are filled with filter media which is being sprinkled with water that has to be treated via a trickling tube.

By and by on the sprinkled filling material a so called bacteria bed grows up. Surplus material will be led out together with the sprinkling water.

A constant gas exchange is one of the advantages of this Biological Trickling Filter. This gas exchange grants a constant oxygen supply of the micro biology and on the other hand harmful gas, e.g. CO2 or Nitrogen (N2) are being emitted into the air.

An additional ventilation is not required.

Sander’s Biological Trickling Filters are suitable for applications in Freshwater and in Seawater.
