Over the last 70 years, microfiltration has developed from a small specialized technology used only in laboratories to a multibillion dollar industry for separation and purification of liquid and gas streams. Especially since the 1980s, exciting new applications have become possible, due to improved membranes (for example, ceramics) and improved technologies (for example, backpulsing, uniform transmembrane pressure). Still, great challenges exist, for example in the processing of beverages, such as fruit juices, milk, and beer, where membrane fouling seriously impairs the economy of the process.

To overcome these problems, researchers and engineers are becoming increasingly interested in hybrid and combined processes. Combining microfiltration with good pre- and post-treatments or with other separation processes may result in better and more economic separations.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
