Offers exceptionally high chemical resistance both in alkaline and acidic applications
Very good chemical and mechanical resistance
Without the addition of mineral components, therefore low ion content
Virtually no ash content, therefore optimum ash
Low charge-related adsorption
Rinsing volume reduced, resulting in reduced process costs
Drip losses reduced in open filter systems
It is usually used in clarifying filtration, filtration prior to the final membrane filter, activated carbon removal filtration, microbial removal filtration, fine colloids removal filtration, catalyst separation and recovery, removal of yeast.
Great Wall C series depth filter sheets can be used for filtration of any liquid media and available in multiple grades suitable for microbial reduction as well as fine and clarifying filtration, such as protecting subsequent membrane filtration step particularly in the filtration of wines with borderline colloid content.
Main applications: Wine, beer, fruit juices, spirits, food, fine/specialty chemistry, biotechnology, pharmaceutical, cosmetics.
Great Wall C series depth filter medium is made only of high purity cellulose materials.
*These figures have been determined in accordance with in-house test methods.
*Effective removal performance of filter sheets is dependent on process conditions.
This information is intended as a guideline for the selection of Great Wall depth filter sheets.
