Abstract
A
major problem in pressure-driven membrane processes is reduction of flux far
below the theoretical capacity of the membrane. Authors report the results of
an experimental study of fouling mechanisms of ceramic membranes in separation
of oil from synthesized oily wastewaters.
Researchers synthesized mullite microfiltration (MF) membranes from
kaolin clay as MF ceramic membranes. They determined that rejection of total
organic carbon (TOC) for the synthetic feeds to be more than 94% by these
membranes. They employed hermia's models to study the fouling mechanisms of
membranes. The effect of pressure, cross flow velocity (CFV), temperature, oil
concentration, and salt concentration on flux decline were investigated. Results
revealed that the cake filtration model can well predict the flux decline of
mullite ceramic membranes; average error of this model is less than 7%.
