“…It main tains the cake in a non-compressible form and provides a porous medium for the flow of the water through the filter. (7). He concluded, from data acquired over a one year operating period on each type of plant, that the cost of di atomite filtration of raw water is approximately equal to the cost of sand filtration plus pretreatment.…”
“…In the precoat filtration equations, the filter cake resistance is indicated by the 6 index. (13) characteristics. For example, Dillingham and Baumann (28) found that a filter aid with a higher Ç index (K^) may possibly form a filter cake with a lower B index (K^), even though Cg and Cp remain the same.…”
