POROUS CERAMIC DIFFUSERS NO FURTHER A MYSTERY

where L may be the thickness in the freshly fashioned sludge residue layer, ρs could be the density of solids particles, (overline n ) is the normal porosity in the sludge residue layer, σ is definitely the retention parameter, qp could be the input flux charge of raw sludge, Ky is the erosion rate, and ns may be the porosity of influent sludge.C
