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

常见问题Common problem

What’s diatomaceous earth stuffing?: For applied structures of diatomite, fillings act as the second largest use of diatomite inferior to filter-aid It is of light-weight, soft-quality, multi-hole, sound insulation, heat-resistant, acid-resistant, large specific surface area as well as stable chemical property and other series of good characters, so diatomite is a kind of functional fillings wildly used in many industrial fields

How about quality stability of products of your company?: Raw materials of our company for producing diatomite filter-aid are completely from self-owned mine and high quality ores with SiO2 more than 85% are used for production Our company persists in inspecting all raw materials, intermediate products and additives and strictly implements ISO9001: 2000 quality management system standards and ISO14001: 2004 environmental management system standards during actual production Tracking for finished products is

Functional Mechanism of Diatomite(diatomaceous earth) Filter-aid: Circulate pre-coating liquid of diatomite again and again to make the first layer of diatomite deposited on the filter medium, and this process is called as pre-coating Then make a spot of diatomite added into original liquid timely, which is called as addition Along with process of filtration, the diatomite added mixes with impurities in the original liquid, depositing on the pre-coating layer, thus new pre-coating layers are formed constantly;

Selection of Model of Diatomite (diatomaceous earth) Filter-aid: Choosing right filter-aid model is crucial to success of use Since it’s different of filter machine, operating environment and technical requirement for each factory, different models of filter-aid in our company could be chosen randomly on the basis of ensuring clear filter liquid and getting most filtration quantities So generally on the premise of satisfying technical requirement, it is a must to search for maximal filtration speed, according

How about chemical stability of Diatomite (diatomaceous earth) filter-aid?: “Tosens” brand diatomite filter-aid has chemical stability and doesn’t’ produce chemical change with the suspension except for the hydrofluoric acid and also is not soluble in fluid phase; moreover, it has low heavy metal content and doesn’t contain poor impurities, dyeing, sand grains and unpleasant odor High-purity raw material, advanced production equipment and high-standard quality management system can fundamentally relieve the client
