Structured filter media Eco Aquarium Structured Garden Koi Pond MBBR floating media bio-block D50mm
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.
Specific surface area for biological activity
When bacteria (biological film or biofilm) grow on a level surface,
the specific surface area will remain constant even with the
establishment of a thicker biofilm. Bio-block, however, is designed
as a helical structure, based on oval threads with a defined
diameter. If these threads become thicker due to growth in the
thickness of the biofilm, the specific biologically active surface
increases correspondingly.
General requirements for biological filter media in order to achieve optimal treatment results:
Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine
Bottle Moulding Machine PET Bottle Making Machine is suitable for
producing PET plastic containers and bottles in all shapes.
1. The filter media should have a relatively rough surface in order
to enhance rapid establishment of a biologically active
surface (biofilm).
2. The filter media must have a structure that makes back wash and cleaning operations on site possible. Canals have to be
vertical and through the entire media column.
3. The filter media must have a structure that ensures optimal oxygen transfer to the bio-film i.e. it must have sufficiently high
porosity.
4. The filter media must never clog and it must have self-cleaning properties. The structure must allow shed biofilm fragments to
pass unhindered throughout the filter.
5. The filter media modules should be constructed with circular or oval threads. Bacterial growth on a circular or oval surface
increases the diameter, thus increasing the specific biologically active surface area.
(Please note! This is in opposition to media with flat surfaces on which the specific biologically active surface area is
constant).
6. The filter media has to be biologically and chemically non-degradable.
7. The filter media must be self-supporting and mechanically strong. It must be able to carry overlying material and personnel
should be able to walk freely and perform service tasks without deformation of the media.
8. The filter media must be UV stable and it must tolerate potential variations in temperature.
9. The filter media should be made from an environmentally compatible material (i.e. no PVC compounds or glue).
10. The filter media must be modular and easy to handle. This will ease installation and potential temporary removal in order to
perform service tasks below the filter.
