The purpose of the research is the experimental study of the filtering kinetics of water fibrous suspensions based on plant fiber of primary and secondary processing and realization on its basis the comparative analysis of filterability for these suspensions.
The research was conducted using the device for determining filtering and dewatering properties of suspensions and sediments by hydrodynamic permeability method.
It was stated that the intensity of suspensions filtering on the basis of primary cellulose fibers is higher than suspensions of secondary fibers. When the grinding ratio of fiber increases the average velocity filtration decreases non-linearly regardless of the type of fibers. Mostly the effect is observed during filtration of suspensions based on primary fibers.
Further research is of interest in order to obtain and summarize data on the filtration rate for different types of fibers in a wide range of grinding taking into account parameters that characterize fibers filterability.References
