Production process Introduction
Source factory, high quality, and low price.
Diatomite for Filtration is a highly porous filter medium made from high-purity diatomite, widely used for clarification and filtration of beverages, oils, chemicals, pharmaceuticals, and fermentation broths.
Advantages
High Filtration Precision: The natural porous structure can trap impurities of 1–10 μm, forming a stable filter layer, resulting in higher liquid clarity and more consistent filtration performance.
High Flow Rate: High porosity reduces pressure drop and is less prone to compaction, increasing filtration throughput by 20–30% compared to ordinary filter aids, making it suitable for continuous mass production.
No Impact on Composition: After high-temperature calcination, it achieves high purity, is non-reactive, and insoluble, ensuring that the filtration process does not alter the color and flavor of food or chemical raw materials.
Everything You Need To Know
Low density, high whiteness, low viscosity, and high purity.
