Water filtration is the process of removing impurities and contaminants from water to make it safe for drinking and other uses. This can be achieved through various methods, including physical barriers, chemical processes, and biological treatments. Common filtration systems include activated carbon filters, reverse osmosis, and sand filters, each designed to target specific pollutants. The importance of water filtration lies in its ability to improve water quality and protect public health. Contaminated water can lead to serious health issues, making filtration essential for households, industries, and municipalities. Proper filtration ensures access to clean water, which is vital for hydration and overall well-being.
