A water purifier is a machine used to remove dirt, germs, chemicals, and other harmful substances from water to make it safe for drinking and use. It is commonly used in homes, businesses, and industries to improve water quality. The purifier may include different filtration stages such as sediment filters (to remove dust and sand), activated carbon filters (to remove bad smell, color, and chemicals), and advanced systems like UV (ultraviolet) light or RO (reverse osmosis) membranes to kill bacteria and remove dissolved salts.
In operation, water first enters the purifier and passes through the initial filter that traps large particles. It then flows through carbon filters to improve taste and remove impurities. In more advanced purifiers, the water is pushed through a semi-permeable membrane (RO) that removes very fine contaminants. Finally, UV light or other disinfection methods kill any remaining microorganisms. The purified water is then stored in a tank or dispensed directly for use.
