Great Wall This high viscosity fluid filter paper has great wet strength and a very high flow rate. Frequently used in technical applications such as the filtration of viscous liquids and emulsions (e.g. Sweetened juices, spirits and syrups, resin solutions, oils or plant extracts). Strong filter with very fast flow rate. Ideal for coarse particles and gelatinous precipitates. Smooth surface.
Great Wall filter paper includes grades suitable for general coarse filtration, fine filtration, and retention of specified particle sizes during the clarification of various liquids. We also offer grades that are used as a septum to hold filter aids in a plate and frame filter presses or other filtration configurations, to remove low levels of particulate, and many other applications.
Such as: production of alcoholic, soft drink, and fruit juice beverages, food processing of syrups, cooking oils, and shortenings, metal finishing and other chemical processes, refinement and separation of petroleum oils and waxes.
Please refer to the application guide for additional information.
