Note: The flow rate calculation of active carbon filter is based on linear
velocity 12m/h; The flow rate calculation of backwash is based on
backwash intensity 10L/(m2*s); The flow rate calculation of sand filter is
based on linear velocity 25m/h; The flow rate calculation of backwash is
based on backwash intensity 15L/(m2*s).
