Attention: the filtering flow rate of carbon filter is calculated based on the
12m/h operation rate; the backwash flow rate is calculated based on the
10L/(m
2
*s) backwash intensity; the filtering flow rate of sand filter is
calculated based on the 25m/h operation rate; the backwash flow rate is
calculated based on the 15L/(m
2
*s) backwash intensity.
