2022 High quality Enzyme Filter Cardboard - K series depth filter sheets for Viscous Liquid – Great Wall Detail:
Depth Filter Sheets Specific Advantages
- High dirt holding capacity for economic filtration
- Differentiated fiber and cavity structure (internal surface area) for the widest range of applications and operating conditions
- The ideal combination of filtration
- Active and adsorptive properties ensures maximum safety
- Very pure raw materials and therefore minimum influence on filtrates
- Comprehensive quality assurance for all raw and auxiliary materials and intensive in process controls ensure consistent quality of the finished products
Depth Filter Sheets Applications:

Polishing Filtration
Clarifying filtration
Coarse filtration
K series depth filter sheets’ high dirt holding capacity for gel-like impurities is specifically designed for the filtration of highly viscous liquids.
Retention of activated charcoal particles, polishing filtration of viscose solution, paraffin wax, solvents, ointment bases, resin solutions, paints, inks, glue, biodiesel, fine/specialty chemicals, cosmetics, extracts, gelatin, high viscosity solutions etc.
Depth Filter Sheets Main Constituents
Great Wall K series depth filter medium is made only of high purity cellulose materials.
Relative Retention Rating

*These figures have been determined in accordance with in-house test methods.
*Effective removal performance of filter sheets is dependent on process conditions.

①Flow time is a time indicator used to evaluate the filtering accuracy of the filter sheets. It is equal to the time it takes for 50 ml of distilled water to pass 10 cm2 of filter sheets under the conditions of 3 kPa pressure and 25℃.
②The permeability was measured under test conditions with clean water at 25℃ (77°F) and 100kPa, 1bar (△14.5psi) pressure.
These figures have been determined in accordance with in-house test methods and the methods of the Chinese National Standard. The water throughput is a laboratory value characterizing the different Great Wall depth filter sheets. It is not the recommended flow rate.
