Diatomite filter aid is a naturally occurring silica mineral that is widely used to improve liquid clarity. Typical grades have bulk densities between 0.18 and 0.22 g/cm³ and particle sizes ranging from 10 to 30 µm, which match the performance expectations for beverage, pharmaceutical and chemical streams. The flux‑calcined process gives the aid a porous structure that enhances flow rates while retaining fine particulates. Suppliers often certify the product to ISO and SGS standards, which the listing confirms.

End users such as beverage manufacturers, pharmaceutical producers and chemical processors rely on this aid to achieve consistent product quality. The supplier indicates flexible minimum order quantities and offers FOB or CIF shipping terms, with payment possible via L/C or T/T. Buyers should request the specific packaging configuration and confirm the trade terms directly with the supplier before placing an order. These steps help align supply with production schedules and regulatory requirements.
