Diatomite For Filtration

Diatomite For Filtration

Diatomite for filtration is produced from natural fossilized diatoms through graded calcination processes, featuring a porosity exceeding 80%. Specially designed for precision solid-liquid separation in industries such as food, pharmaceuticals, and chemicals, its uniform microporous structure efficiently captures suspended particles, colloids, and microorganisms ranging from 0.5 to 30 μm, significantly improving filtrate clarity. Certified for pharmaceutical-grade safety, it poses no risk of leaching contamination.With strong chemical inertness, acid/alkali resistance, and no alteration of solution properties, this filter aid is compatible with equipment such as plate-and-frame filter presses and centrifugal separators. Its low fouling characteristics reduce system resistance by 40%, extend filter element lifespan by 30%, and produce loose, easily removable filter cakes, cutting solid waste discharge by 50%. Combining high-efficiency filtration with circular economy benefits, it is an optimal material for sustainable industrial production.
