High Quality Natural Fiber Cement Additive Quick Setting Siliceous Earth Powder Cellulose Filter Aid

For compressible filter cakes, adding filter aids can enhance their rigidity and prevent increased filtration resistance. When filtering suspensions containing viscous fine particles, a dense filter cake layer is often formed. Adding filter aids can change the structure of the filter cake and reduce the resistance of the filter cake. The pre coating of the filter aid can withstand a certain pressure without deformation, and can prevent the filter cloth from increasing resistance due to clogging.

Substances that can improve the filtration efficiency of the filtrate. Insoluble inert materials with different degrees of fineness are used to prevent excessive compaction of filter residue and smooth filtration. In filtration operations, an auxiliary powdery substance added to reduce filtration resistance, increase filtration rate, or obtain highly clarified filtrate is called a filter aid.
