4.2 Maximum filtration flow Comments

The filtration flow rate shall be adapted to the nature and surface area of the filter medium used in the filter

The velocity at which the water to be filtered passes through the new filter medium shall be adapted to the type of medium used.

Granular media filter : low rate ≤ 10 (m3/h)/m2

Granular media filter: medium rate > 10 (m3/h)/m2 to ≤ 30 (m3/h)/m2

Granular media filter: high rate > 30 (m3/h)/m2 to ≤50 (m3/h)/m2

Vmin = Q/S = 10 (m3/h)/m2 S = 0.08 m2 Q = 0.8 m3/h Vmax = Q/S = 50 (m3/h)/m2 S = 0.08m2 Q = 4 m3/h
