Ceramic Filter
?
Ceramic filter has large surface area,high void fraction,less impurities high speed of filtering,long working period, and so on.
?
Ceramic filter is made of fine ceramic mud added achoring agent and binder. After griding, screening, shaping and sintering, we make it. It is a kind of global pellet, of which the size is uniform, the surface is solid. This product has much merit, such as large surface area, high void fraction, less impurities high speed of filtering, long working period, little water consumption during washing back, and there is nothing harmful to the body of man. It will decrease the volume of the disfectant and cloud point, the effect of separating N.H3Pis over 99%, and that of separating CoDcr is over 40%. This product can improve the effect of filter material instead of quartz sand and anthracite.
