Study of series resistances in high-shear rotary ultrafiltration

摘要

A parametric waste-specific study was conducted to determine the relationship between permeate flux, transmembrane pressure, membrane rotational speed, and feed concentration in the high-shear rotary ultrafiltration (HUSRUF) of a synthetic metal working (MW) fluid. The interactions between permeate flux and operating parameters were described using the resistance-in-series (RIS) approach to flux modeling. Eighteen discrete experiments were conducted at constant MW fluid concentration/membrane rotational speed combinations at applied pressures ranging from 103 to 517 kPa (15 to 75 psig).
