Biostyr biofilter

1. Using polystyrene spherical light filter material.

2. Upward flow is adopted, and air and water flow in the same direction.

3. In upflow filtration, the filter bed of floating media is kept under the nozzle bottom plate. The tip of the nozzle only touches the treated water, which is easy to maintain (filtration in the direction of medium pressure).

4. The polystyrene filter bed provides biofilm growth, and the dense media bed is used to remove suspended solids.

5. Adopting porous pipes for aeration, corrosion-resistant materials, saving equipment investment and reducing required maintenance.

6. Water and air flow at the same time, and the same blower is used for process air and backwash air.

7. Backwashing uses treated clean water to perform backwashing under the action of gravity without an additional water pump.
