Introduction: Based on previous ceramic sand
filter, we developed a new filter, with the characteristic of large specific
surface; strong decontamination capacity; high water yield; long filter cycle,
Ceramic Sand Filter effectively solves industry effluent and urban sewage.
Aiming at conventional product’s defect, and in the opinion of new filter
development, we adopt porcelain clay; agglomerate; pore-forming agent and CRE,
through heating agglomeration, it shows white color; hard texture; even-grained;
high porosity and good roundness. It is applicable for Chemical Plant; Oil
Refinery; Electric Power; Pharmaceutical Factory; Galvanization; Paper Mill and

1. Big voids on the
surface of ball, normally, its filtering velocity is 15-20m3/h, with small head loss; it lowers filtering
tank’s height and saves electric power and infrastructure expense.
2. Because of even and regular in
particle size, making it easy to be cleaned, the back-flush strength is 12-20
l/m2, so the water consumption could be reduced 30-50％.
3. Large surface area and pore
volume; strong decontamination capacity, generally with 9～10kg/m3, it is as 1.2 ~ 1.5 times as quartz sand
4. High strength; small abrasion;
usage life is over 15 years.
5. Well distributed; easily
packed; uneasy to wash away; none secondary pollution; it is applicable for ion
exchange, mechanical filter, valveless filter chamber, reverse osmosis system.
It is usually pretreatment or supporting layer in reverse osmosis system which
used for supporting layer of activated carbon adsorption.
6. According to water quality and
special fabrication processing, the porcelain sand filter material is able to
free from iron, Mn, fluorine.
