It is an ideal filtering material, especial in filtering pool and oil filtering pool in water plant and oil refinery.

It has the characteristic of strong capacity, fast filtering speed, long period and low strength in anti-washing and sewage treatment. Ceramic granule filter is a new type of filter which is able to increase the water production; improve the water quality and save the energy loss; therefore it is an ideal filtering material, especial in filtering pool and oil filtering pool in water plant and oil refinery.

Usage:The filtration materials of ceramic particle can not only improve the filtration efficiency and reduce the cost, but also have as high effect of de-nitrogen, de-ammonia, de-phosphor as to 99%, it is the ideal replacement for quartz sand and anthracite.Chemical Position:
