AN UNBIASED VIEW OF CONTINUOUS SAND FILTER

the place L could be the thickness in the freshly formed sludge residue layer, ρs is definitely the density of solids particles, (overline n ) is the average porosity on the sludge residue layer, σ is the retention parameter, qp could be the input flux charge of raw sludge, Ky may be the erosion charge, and ns is the porosity of influent sludge.T
