Processing of dilute liquid streams in the industries like food, agro-, biotechnology, pharmaceuticals, environment, and so forth\nneeds special strategy for the separation and purification of the desired product and for environment friendly disposal of the waste\nstream. The separation strategy adopted to achieve the goal is extremely important from economic as well as from environmental\npoint of view. In the present paper we have reviewed the various aspects of some selected universal separation strategies such\nas adsorption, membrane separation, electrophoresis, chromatographic separation, and electroosmosis that are exercised for\nprocessing of dilute liquid streams.
