Depth Filter Sheets Standard Series

Short Description:

Great Wall Standard Series Depth Filter Sheets For a wide range of applications

The Standard Series has a broad range of retention grades which seamlessly cover 20.0 to 0.2 µm. This ensures the filter media meets demanding liquid filtration requirements.

Due to its’ optimum pore structure and adsorption properties, the depth filter sheets have an excellent clarification performance in multiple grades, suitable for microbial reduction and applications requiring polishing, fine, clarifying, and coarse filtration.

    Standard Series Depth Filter Sheets Application:

    Standard Series Depth Filter Sheets For a Wide Range of Applications

    Clarifying Filtration and Coarse Filtration
    SCP-309, SCP-311, SCP-312 depth filter sheets with large-volume cavity structure. These depth filter sheets have a high holding capacity for particles and are especially suitable for clarifying filtration applications.

    Microbe Reduction and Fine Filtration
     SCP-321, SCP-332, SCP-333, SCP-334 depth filter sheets for achieving a high degree of clarification. These sheet types reliably retain ultrafine particles and have a germ-reducing effect, making them particularly suitable for haze-free filtering of liquids prior to storing and bottling.

    Microbe Reduction and Removal
    SCP-335, SCP-336, SCP-337 depth filter sheets with a high germ retention rate. These sheet types are particularly suitable for cold-sterile bottling or storing of liquids. The high germ retention rate is achieved through the fine-pored structure of the depth filter sheet and electrokinetic potential with an adsorptive effect. Due to their high retention capacity for colloidal ingredients, these sheet types are particularly suitable as prefilters for subsequent membrane filtration.

    Main applications: Wine, beer, fruit juices, spirits, food, fine/specialty chemistry, biotechnology, pharmaceutical, cosmetics and so on.

    Standard Series Depth Filter Sheets Main Constituents

    The Standard Series depth filter sheets are made from particularly pure natural materials:

    • Cellulose
    • Natural filter aid diatomaceous earth (DE, Kieselguhr)
    • Wet strength resin
