Plastic Filter Media (Filter Media)

Biofiltration media:
Biofiltration media is merely a mass of surfaces serving as the attachment basis
for microorganisms. The spacing between these surfaces is important, both for the
passage of water and to provide sufficient room for bacterial growth. Try to filter
out solids prior to the biofilter.

Features:  
1) Bio-barrels: a polypropylene media available in 5 sizes, positive in buoyancy,
    natural in color 
2) Plastic media balls can be used in trickle towers, degassing towers, wet/dry
    filters, canister filters, pond filters overflow boxes, sumps; use them for 
    biological filtration, increasing gas exchange and improving filter performance

3) Biocord is an economical biofilter media that consists of a center cord covered
    with countless rings of thread. The threads have a slight positive charge and,
    when placed in water, attract bacteria and solids that, in nature, have a slight
    negative charge. It is commonly used in lakes, ponds, sewage treatment 
    facilities and in the aquaculture industry 

Ceramic filter media:
Ceramic grain filter is made of high quality argil. Appending with hole-former and
bonder, the granules of spherical shape form after ball grinding, filtering, moulding
and calcining. The product has uniform granule, red and brown appearance,
flinty and porous surface, interlaced with holes and net as well as strong absorption
function. In the water treatment, it has the characteristic of strong capacity
in sewage treatment, fast filtering speed, long period and low strength in
anti-washing. Ceramic granule filter is a new type of filter which can increase
the water production, improve the water quality and save the energy loss, therefore
an ideal of filtering material in water plant, filtering pool and oil filtering
pool in oil refinery.

Physical properties:
1) Appearance: spherical, surface with red brown, porous
2) Grain diameter: 0.5 - 32mm
3) Sight density: 1.0 - 1.19g/cm³
4) Density: 2.26g/cm³
5) Void space: 55%
6) Breaking and wearing rate: 1.62%
7) Non uniform factor: K80=1.84
8) Uniform factor: K60=1.47
9) Soluble rate of HCL: 2.83%
10) Soluble rate of NaOH: 1.50%
11) Solute: no dangerous rare element to human
12) Absorbing capacity: 101 grade of value is 10% absorbing capacity of active carbon


Ceramic filter ball/sand media:
Ceramic filter ball / sand  media has stable chemical performance, including attrition
resistance, corrosion resistance, high temperature resistance, large specific
surface area, strong sewage treatment capacity, good absorption, uniform granule,
appropriate specific weight, and long lifetime. This product is widely used
in the single layer filtering pool, multi-layer filtering pool and mechanical
filter, to deal with various industrial water, city tap water, city sewage, pure
water, soft water, and act as biologic filter to treat organic sewage. Moreover,
it can deal with various industrial dust and soot of boiler. Because of the accession
of anti-corrosive rare earth in the lanthanide and actinide series, apart
from the performance of common ceramic sand, the performance in anti-corrosion
is further improved, and contain more stable SiO2, particularly suitable
for chemical water treatment in boiler and production of super pure water.
