Sand Filtration

Sand filtration is a water purification process that uses layers of sand to remove particles, dirt, and impurities from water. As water passes through the coarse and fine sand layers, contaminants get trapped, resulting in cleaner water. This method is effective for filtering large particles and some bacteria, commonly used in drinking water treatment and swimming pools. The sand acts like a natural sieve, allowing water to flow through while capturing unwanted materials. Regular maintenance, like backwashing, is necessary to keep the filtration system functioning efficiently.
