Preparation of filter aids based on diatomites
This method was selected due to high ratio of very fine primary diatomite particles (1–5 μm) in dried semi-product. The fine particles decrease the flux because of high resistance to flow. Hence, it is necessary to provide size distribution of the filter aids particles that have its maximum in the range of 5–40 μm.
Radiolite® Diatomite Filter aids and Fillers | Our Products
Accumulations of fossilized diatoms frustules form deposits of diatomite, the raw material from which Radiolite ® products are processed.
