Physical-chemical and biological particle removal mechanisms in slow sand filters were investigated at bench scale. Physical-chemical particle removal mechanisms were significant for particles throughout the size range analyzed (0.75-10 um). Influent particle concentration and previously removed particles affected physical-chemical particle removal. Particle removal efficiency increased with particle accumulation within the filter bed.
