As diatomite is of unique micropore structure and particle distributing, which could form filter layer of high-infiltration after processed into filter aid, accordingly able to hold up various particles of impurities, getting rid of the tiniest suspending solid, even including particulate impurities of 0.01 micron, thus making filter liquid cleaner and cleaner. So it gains good reputation of natural molecule screen being an ideal material adopted at large in filtration industries at present. Nowadays, diatomite filter-aid has been widely used for solid-liquid separation and liquid purification in many industrial departments.
