The structured filter media Bio Block is extruded from high-density polyethylene (HDPE) and welded to form a three-dimensional grid processing unit. The unique reticular tube structure on its surface provides a special culture medium for microorganisms. The surface of the Bio Block is relatively rough, which enhances the ability of bacteria in wastewater to grow on the carrier. These strains can widely treat and degrade organic impurities in wastewater. The surface of Bio Block is used as the culture medium of special strains, and its treatment ability depends on its specific surface area. The larger the specific surface area, the more bacterial population and the better treatment capacity.

In biological wastewater treatment, it has unique flexibility, which can improve the capacity of treatment flow change and load.
About 70% carbon dioxide can be removed and PH balance can be maintained by trickle filtration. The dissolved oxygen can be greatly increased to 5mg / L by water fall. It can also be used as solid bed packing instead of brush packing to culture biofilm and remove nitrite effectively.
In practical engineering application, the structured filter media Bio Block has modular design, easy installation, no support, and can be used in any pool type; high strength self-supporting system, lightweight and deformation free; mesh porous structure, to ensure full gas-liquid exchange, enhance dissolved oxygen content; self-cleaning, biofilm does not block. It is a new direction of packing selection.
Bio-Block
Bio-Block has been widely used in small sewage treatment projects in Europe, involving domestic sewage, industrial wastewater and aquaculture wastewater.
