Ceramic Grain Filter,Water Filter: 

Ceramic grain filters are made of refined pottery clays added with certain modifiers, and processed of grinding, 

mixing, shaping and high temperature sintering. They do not contain any substances that harmful to people or 

environment. They are hard and rough in surface, porous inside the structure, and have the advantages of high 

mechanical strength, large specific surface area and porosity. When used in water treatment, they behave a  activated surface property, a great amount of  pollutant entrapment,less water  head loss in the filter bed,  lower 

consumption of back-flush water, stable in chemical and gbiologic property, and long service life.  Ceramic grain

filters is a new and efficient filter material toincrease the water yield,upgrade the water quality, and save chemicals

and energy.

Ceramic grain filter advantage:

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.
