Pottery Grain Filtering
    Pottery grain filtering is the further processing products of shale ceramic grains. It has enough mechanical strength to avoid due to rubbing during washing. Its enough chemical stability makes it indissoluble in alkaline, neutral, acid water or oil, and be certain grain. Its surface is rough with edges, can not only ensure the filtering speed, but also absorb the dirt to suit and meet the purifying design requirement of water and oil. Pottery grain filtering is the ideal filter material for water factor, filter and oil-filter of oil refinery, have the function to remove the element of iron and manganese.

Ceramic Grain and Sand filtering
    Holding stable chemical characters , anti-friction, anti-corrosion, high resis-temperature, specific surface area is bigger, stronger intercepting ability, good absorbing, size of grain is uniform, suitable specific gravity. Its service life can be long, solved the single specific density of natural grain and the problem of air would polluted second time came from silica and organic-carbon because of the natural grain is easy broke. It can be wildly used in the single-layer and multiplayer setting basin, as the filter medium. It can be used to dispose all kinds of polluted water or used in the industry, and top-water and sewage of city, pure water, soft water. It also can be used in the filter dirt catcher to dispose all kinds of industry power dusts and chimney of boiler.
