Fluidizing biofilter with a movable bed

Biofiltr Hygger with a movable bed works on the principle of fluidization phenomenon. Fluidization is a process for the formation of a dynamic suspension of the so-called Fluidous bed. The fluidized bed consists of a solid particle, in this case a filter bed moving in a stream of air and water from below.

The volume of the Ziofilesco HyGGER biofiles is approx. 50% of the total filter capacity. The bed has a special structure and density similar to the water density, but less than it. Such a value allows you to float freeze in a water tone and circulate inside the filter from below up under the influence of small air bubbles

Biofiltr Hygger contains a large-specific filter deposit on which nitrification bacteria develop. The bed provides a maximum surface to increase these useful bacteria, supporting the nitrification cycle. Nitrification is an oxygen process and requires oxygen to its course. A very intense aeration significantly increases the oxygen saturation in inside the filter and thus intensifies the nitrification process.

In the nitrification process, the nitrosomonas type bacteria and the type of Nitrobacter which are successively "process" "ammonia" - NH4 to Natrins NO2, and then to the least harmful NO3 nitrates, which in the tank They are used mi.in. Through plants. In fact, the mechanism of the nitrification process is more complex and depends on many factors.
