ABSTRACT
Environmental engineers have invented very large numbers of processes and devices for removal of pollutants from various water phases and soils. Recently, material engineers and environmental engineers have begun fusing their technologies to improve efficiency of environmental process. Material engineers found new applications of their materials, at the same time environmental engineers could enhance performance of their processes by just adding materials without big modification in the process (technically no modification). Users and engineers keep trying to find magical materials that can improve the efficiency and reduce the cost of their environmental engineering process by just adding small amount of magical materials. That is, antifouling agent, coagulants (aluminum sulphate, ferrous sulphate, ferric chloride, polyelectrolyte), sedimentation, activated carbon, surfactants, microorganism, etc., have been used for enhancing efficiency of environmental process, which is running in real field [1-3].
