| Diatomite is porous with lower density and larger surface area; it has relative incompressibility and chemical stability. Diatomite as the important raw materials, after grinding, drying, sorting, calcined, classified, residue removed, we get the thing that can improve the quality and efficiency of filtration is called Diatomite Filter Aid.
According to the size of its permeability, the diatomite filter aid can be grouped CD10, CD090, CD080, CD070, CD071, CD061, and CD060 in seven grades. According to the production process method, the diatomite filter aid can be grouped in calcined and flux calcined two types. In the industrial applications, according the purposed liquid and the types of filter, people choose one or two of filter aids to use in order get the efficient filtrating. Our CD series diatomite products compliance with the Health of the People's Republic of China <GB14936-94> diatomite health standards, and meet the special sanitation requirements of the food and pharmaceutical industry. And we have the "Health Permits" issued by Zhejiang Provincial Health Department.
