This unique and patented system allows the water to flow through hundreds of razor sharp triangular blades which are mounted (depending on the model) with gaps of 50, 100, 150 and 200 micron (1 micron=0.001mm). The water runs against the sharp side of the blade where the surface tension of the water is broken. The dirt particle, whether sinking or floating is pushed away from the sieve due to the Hydrostatic load created, this causes the solids to be lifted out of the water. The dirt from the water is then moved to the base of the sieve where there is no water running and can be removed easily. This dirt can not pollute the water anymore by dissolving. This system will work superbly in the place of vortexes and especially brush chambers. Both of the filters mentioned are absolutely not necessary anymore, and it is even better to remove them completely.
