Optimization: Direct Flow Filtration Searching for the optimal product: Performance • Consider • Nature of contaminant • Level of control required • Process volume • Process time • Material suitability for: • Compliance • Compatibility • Simulate • Filter size • Filter type • Process Details • Maximum volume • Maximum contact time • Maximum flow rate • Maximum pressure • Establish • Filter capacity • Filter type • Rating • Format • Peak flow • Differential pressure Process Requirements Filter and Process Options Validation Parameters
Impact of Filter Grades on Flow Vs. ΔP • ΔP is directly proportional to Flow rate (Q) (at a given grade) • ΔP at a given flow rate is generally higher for finer filter grades of the same filter type 12 10 8 Differential Pressure (psi) 6 Flow rate (L/min), water at 20 C per 254 mm (10 in.) Module For liquids other than water, multiply differential pressure by fluid viscosity (cP). 4 2 0 DJL (0.1 µm) DFL (0.2 µm) DBL (0.45 µm)
