Efficiency of physical–chemical particle removal increases with particle accumulation within the filter bed. 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 μm). Influent particle concentration and previously removed particles affected physical–chemical particle removal. Particle removal efficiency increased with particle accumulation within the filter bed.
