Introduction
Membrane filtration is a technique used to separate a liquid from any particles present in it. In membrane filtration, a liquid is passed through a semi-permeable membrane. The size of the pores on the membrane determines its permeability thereby enabling the membrane to act as a barrier to all particles larger than the pore sizes. Different approaches and systems can be employed in membrane filtration depending on the type and capacity of the liquid being purified but the overall goal is to obtain a clean liquid. Membrane filtration can be used in the treatment of wastewater, filtering milk during its processing among other applications. This ...
