Diatomite is a diatomite deposit deposited by the remains of unicellular aquatic algae under certain geological conditions. Diatomite has the characteristics of porosity, large specific surface area, low density, good adsorption, acid resistance and heat resistance. Its main component is amorphous SiO2.

Diatomite filter aid is a powder product made from diatomite. In industrial production filtration, it is a filter aid material used to help the filtered liquid improve filtration speed and clarification.

Filter aid: filtration is a very common physical treatment method to remove insoluble substances in liquid. Because the solid substances in the liquid are often some substances with fine particles, amorphous, soft viscosity and easy to block the holes of the filter cloth, such as filtration alone, it is often difficult to filter, the filtrate is not clear, and the filter residue layer cannot be formed (only some slurry is formed on the surface of the filter cloth), so it can not be used in practice. Adding filter aid to the solution or pre coating a layer of filter aid on the surface of the filter cloth can significantly improve this situation, with fast filtration speed, clear filtrate, compact filter residue and falling off from the filter cloth. Diatomite is the most commonly used filter aid in various industries.

Because of its unique pore structure, different particle size distribution range and stable chemical properties, it can not only obtain a high flow rate ratio of the filtered liquid, but also filter out fine suspended solids, with a minimum of 0.1-1 μ M impurity particles. Therefore, diatomite filter aid can greatly improve the filtration capacity, improve the clarity, improve the production efficiency and reduce the filtration cost.
