James-Cumming C & S - Sand Filter for Water Treatment

They allow water to pass through a bed of the graded filter sand, physically trapping suspended particles and removing impurities as the water passes through.

During this process, the largest particles settle at the bottom while the smallest stay on the top. This uneven dispersion limits the utilisation of media depth, concentrating filtration at the surface. Consequently, the filter operates in shorter cycles, requiring frequent backwashing.
