Sand filters are critical components of water filtration systems, effectively removing pollutants and particles to provide crystal-clear water. These filters use specific graded sand as a filtering medium, trapping particles and producing clean water.
Manual Sand Filters: To remove trapped pollutants, manual sand filters must be backwashed on a regular basis. This technique involves reversing the flow of water to remove trash from the sand bed and direct it to junk. While manual, this procedure is effective and guarantees that the filter continues to function properly. Regular monitoring and maintenance are essential for optimal operation.
Automatic Sand Filters: Automatic sand filters provide a more convenient, hands-free filtration experience. These filters have programmable control valves that start the backwashing operation at specific intervals. The automation eliminates the need for regular supervision and ensures that the filter performs optimally without personal intervention.
