Summarization on Technology and Applications of the Microfiltration Membrane

With the development of membrane manufacturing technology, the treatment of produced water of oilfield by microfiltration membrane is thought that have more and more advantages. The characteristics and filtration separation principle of microfiltration membrane have been expounded. They were compared and analyzed respectively that advantages and shortcomings, technology of preparation and applications of different microfiltration membrane, such as organic-polymer, inorganic-ceramic and composite one in oilfield. Because the flow rates of membrane descend quickly and the effective time is short when the membrane worked, some measures have been advised to prevent fouling of the microfiltration membrane and clean it. Furthermore, the prospect and some advices for development of the microfiltration membrane technology and the future application of the membrane in oilfield have been brought forward.
