Bio Filter Working Principle
The bio filter equipped with sponges or sponge（HBF I-2 to HBF I-6）and Crystal Bio (HBF II-2 to HBF-II-6) in the two floors of filter chambers. First, the polluted water input through bigger pipes below the sponges. Because of this Vortex-Effects, the big inlet pipe is tangential connected, making the water in the filter a slowly rotation that leads to a sinking of the bigger waste particles. Only the small, most biological particles are flowing through the sponges. So, the sponges don’t get clogged frequently. That also gives the sponges a very long life time.
The small particles as well as the dissolved organic substances can be cleared. Through nitrification and de-nitrification in deeper sponge layers the waste is transformed into nitrogen (N2) which discharges into the air. In the vertical lower filter chamber a second filter process can be implemented by using Crystal Bio filter media (HBF II-2to HBF II-6). The already well cleaned water can be additionally cleaned by De-Nitrification from biological waste to reach totally clear condition without any Nitrat.
Using our Bio-Filter, there isn’t the problem with algae in the pond!
The Bio-Filter of HDPE must prevent from sunshine. The UV-light can destroy the filter, also the heating of sunshine can lead to the filter instability!
