Biochamber BK900

 The holes in the compartments are 12 mm in diameter, making the biochamber ideal for 13, 15, 17, etc. Helix or other filter media. The chamber has been divided by a partition so that we have two biochambers available, each with a separate membrane vent. Each vent is powered by its own membrane pump. The biochamber can be used in both gravity and pump versions. The biochamber is supplied with a lid.

The moving bed filtration process is also called the fluidized bed process. This process is used in industrial wastewater treatment and in aquaculture facilities. In the moving bed process, the filter material is additionally agitated by blowing air. A distinction is made between a protected and an unprotected surface for the filter material.

This means: The unprotected surface is the inner and outer surface of the filter medium. A protected surface means that only the inner surface of the filter material is protected. In the moving bed process, the filter material moves through the air and rubs against itself. This means that bacteria that have settled on the outside of the filter material are constantly removed. When choosing a filter material, you should definitely pay attention to the protected surface for the moving bed process. In order to avoid a high level of contamination of the filter material, it is very important to use good mechanical water cleaning before the filter (drum filter, fleece filter, etc.).

Effective turbulence of the filter material is possible if only 40% of the water volume is filled with filter media.
