Membrane filtration techniques are essential tools in the field of water purification. These processes leverage selectively permeable membranes to remove contaminants from water, resulting in a purified output. The effectiveness of membrane filtration hinges on the size and properties of the membrane pores, which dictate the types of contaminants that can be captured. Common membrane filtration techniques include microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Each method possesses unique characteristics and is tailored to target specific pollutants. Microfiltration removes larger particles like suspended solids, while ultrafiltration targets smaller entities such as bacteria and viruses. Nanofiltration tackles dissolved salts and organic molecules, and reverse osmosis achieves the highest level of purification by removing virtually all contaminants, including ions and even some uncharged molecules.
