All FIAP filter systems are working with the UP-FLOW principle. The water will lead by a below prefixed degrading chamber through the filter medium. Thereby the inside the water contained suspended sediments degrade in the chamber for waste before the water flow through the filter medium.
By this measure the biological degradation process will fewer polluted with not solvable suspended sediments and works consequently more effective than customarily systems. FIAP filter systems are complete manufactured with stainless steel. The interpretation and technical concepts based on our research result relating by degrading capacity at non-pressurized filter systems. At FIAP filter systems the inflow and perfusion speed of the filter medium will optimal ensured for a effective biological nitrogen processing.
In the seat of the company NUMA is placed whole Fiap Active Jumbo filtrating system with 300µ filter with three modules fullfiled filtrating brushes, T-mat and bio cubes. This filtrating system also includes pump with dual suck, skimmer and 110W UV-lamp. You can come and persuade yourself about the effectiveness of this high-quality filtrating system in the pond with the content of 33m3 water.
The filter medium as carrier of the microorganismus is the heart of biological circulation systems. The surface should be as big as possible by low pressure resistance and through the pores should be guaranteed a permanent high inflow of the formed biofilm. Thereby on depending of pollution the water with suspended sediments different pore sizes will get deployed. The formed biofilm works different conditional on inflow speed and oxygen contend. Filter medium from FIAP has a inside surface up to 2,5m2/l.
More filter area = more degradation power
In a biological filter system are aerobic, anoxic and anaerobic zonal whereas the zonal with relative high inflow and high oxygen contend inside the water will called aerobic zonal. In FIAP filter system both zonal gets cultivate so a nitrogen removing is also as far as possible enabled.
A biological filter system works most effective per fewer the water is not polluted with not solvable suspended sediments. Consequently it is absolute required to equip the water before the biological preparation with a mechanical coarse protection separator. In dependence of water volume per hour a micro screen filter or a drum filter are working most effective.
