Porcelain Sand Filter

Size: 0.5-32mm Big Void , Large Surface Area,easily packed ISO9001:2008

Filtration materials of porcelain sand has the merit of steady function, ant-blasting, wear resisting, strong head resisting the size of product is uniform, damming the impurities very well, solving that problem that quarts sand is easily broken and muddy and come out SiO2 and leave over liquid coal.

Ceramic sand filter chemical Composition:

Ceramic sand filter size:

Layer	Floor
Φ0.5mm~Φ1.0mm	Φ8.0mm~Φ16.0mm
Φ1.0mm~Φ2.0mm	Φ016.0mm~Φ24.0mm
Φ2.0mm~Φ4.0mm	Φ24.0mm~Φ32.0mm
Φ4.0mm~Φ8.0mm

ceramic sand filter advantage as below:

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 filtering.

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.
