Sand Filter an overview ScienceDirect Topics

In rapid sand filters the loadings typically run as high as 20 gpm/ft 2 (14 lps/m 2 ), although one would be very unwise to use such values with raw seawater More reasonable maximum values would be about a quarter of this number Their head losses when clean can be in the order of 30–90 ft (91–274 m)

Relationship between the head losses in the sand
