Pressure Sand Filter
A pressure sand filter is a vital component of water treatment systems, used to remove suspended solids and impurities from water. Consisting of a tank filled with specially graded sand, these filters work by forcing water through the sand bed under pressure. The sand traps particles and contaminants, allowing clean water to pass through.
The process begins as water enters the tank and flows downward through the sand bed. The sand’s unique grading allows for effective filtration, capturing particles ranging from large debris to microscopic impurities. As water moves through the sand, suspended solids are trapped, resulting in clearer and cleaner water.
Regular maintenance is crucial to ensure the filter operates efficiently. This includes periodic backwashing, where water is pumped in reverse through the filter to dislodge and flush out trapped particles. Pressure sand filters find applications in various industries, including municipal water treatment, swimming pools, and agriculture, providing a reliable method for improving water quality.
