Slow sand filtration definition

Slow sand filtration means a process involving passage of raw water through a bed of sand at low velocity (generally less than 0.4 meters per hour (m/h)) resulting in substantial particulate removal by physical and biological mechanisms.

Slow sand filtration means a process involving passage of source water through a bed of sand at low velocity (generally less than 0.10 gpm/ft2) that results in substantial particulate removal (˃ 2-log Giardia lamblia cysts) by physical and biological mechanisms.

Slow sand filtration means a process:
