Study on purification resistance of wet fiber layer filtering of non-steady-state

Key words: 
• wet filtration /
• non-steady-state filter /
• fibre layer /
• purification resistance

Abstract: Based on the theory of purification resistance of dry fiber layer filter, the basic of assumption that the cleaning fluid (water) evenly distributes on the surface of fiber was proposed, the analysis of the droplets,liquid film in the wet filtration was simplified. The disciplinarian was concluded about purification resistance changing with time, then the expression of purification resistance was induced about wet fiber layer non-steady-state filter. Finally it is proved to be accurate through the experiments.
