Two-phase limiting flux in high-shear rotary ultrafiltration of oil-in-water emulsions

摘要

A study was conducted to assess the effect(s) of high oil concentration on the pressure-independent `imiting' permeate flux and theability of a thin film model to adequately predict the flux in the treatment of synthetic and waste metal working fluids using the high-shear rotary ultrafiltration (HSRUF) system. Two distinct limiting flux regions were ascertained, in contrast to a discrete flux decline with concentration predicted from the thin film model.
