Membrane separation techniques are widely used in separation and spectroscopic methods for efficient purification and industrial processing. In water treatment, membrane technologies such as reverse osmosis, ultrafiltration, and nanofiltration play an important role in removing contaminants. Reverse osmosis is extensively used for desalination of seawater and brackish water by applying pressure to force water molecules through a semi-permeable membrane while retaining dissolved salts, bacteria, and organic impurities. Ultrafiltration membranes help in removing suspended solids, colloids,
