Porous Ceramic Ball
Porous ceramic filtering media is made of tiny particles through the very complicated technological process in which this kind of particle can be put in shape according to a specific size and proportion and then sintered in a kiln to be hard ceramic materials with porous and rough surface. Its main ingredients are SiO2, Al2O3, and Fe2O3 eTC, compared with arenaceous quartz filter, it has developed voidage and large specific surface area.
Porous ceramic filtering media is spherical particles features with more micropore, high strength, long service life, corrosion resistance, good adsorption capability, appropriate density, and not easy being agglomeration, which is the ideal filter that can replace those traditional filters such as the arenaceous quartz, anthracite, walnut shell filter etc.

the initial hydraulic head loss of the filtering layer is small, and the filtration cycle is long; the terminal hydraulic head loss is small, which can save a certain amount of filter.
The ceramic packing material is with good feculence interception capability, usually in the speed of 10-11kg/cm3, about 1.2 to 1.3 times to arenaceous quartz (7.8-9 kg/cm3).
with a spherical surface that is easy to keep clean, and small backwash water that 30% -40% less than arenaceous quartz is .
ceramic filter material is high hardness, high strength, small attrition rate, life expectancy is 10 times more than the arenaceous quartz.
