Methods of Water Treatment : Methods of Water Treatment Chemical Treatment: Chlorine Iodine Ozone Ammonia (remove taste of Cl) Sedimentation: Allowing suspended particles (like sand) in water to settle down. Contd. : Contd. Filtration: Remove suspended particles from water by passing it through filter media. Aeration: Air is passed through filtered water to remove bad odors. Nanofiltration (NF) : Nanofiltration (NF) Nanofiltration is a form of reverse osmosis. It removes: Bivalent ions (Ca2+ ,Mg2+) that cause hardness in water Peculiar smell and color Pesticide Synthesized surfactants Dissoluble organic material Typical pore size 0.001 microns Operating pressure (medium) 10-50 bars. Principle : Principle Cross-flow filtration technology. Nanofiltration System : Nanofiltration System Applications : Applications Advantages : Advantages Environment friendly Require a minimal amount of power Typically small in size so works well in home filtration systems Do not affect the taste of the purified water Removes dissolved minerals and other contaminants Disadvantages : Disadvantages Require an enormous amount of water Takes a long time to properly treat the water You do not have the permission to view this presentation.
