Research on Variables Affecting Filtration

Water and waste water filtration. Concepts and applications

“…The right-hand side of Equation 4 is seen to vary with r°to it1, µ°t o µ-1, d~y to d~3, and dP~213 to dP2 depending on the transport mechanism which is operative. These results correspond to the range of results observed by other investigators in laboratory experiments and in practice (Ives and Sholji, 1965). The effects of filtration velocity, water viscosity, media size, and the density of the suspended particles on the single-collector efficiency are presented graphically in Figure 4.…”

Flow of Suspensions through Porous Media—Application to Deep Filtration

“…Yao (74) really observes by experiment the existence of such a minimum. Iwasaki (35) found \/(dgUm3•3) but Ives (34), taking again Iwasaki's experimental results, finds Xo \/(dgum).…”

Progress in Induced Coalescence and a New Theoretical Framework for Coalescence by Porous Media

“…Equation 24a predicts a constant slope of the relative permeability to the nonwetting phase vs. saturation in the neighborhood of the limiting nonwetting phase saturation, which occurs at Snc = 0.10. Jones obtained Equations 24 from experiments with oil as the nonwetting phase, and water as the wetting phase in granular solids. Observe that Equation 246shows no permeability cut-off for the wetting phase.…”

“…(25) summarized his data on sand filtration of E. coli (reported as B. coli) volume deposit per unit volume filter, dm is in microns, and q is in m/day.Ives and Sholji(24) summarized their findings on sand filtration of polyvinylchloride spheres (1.3-µ di-…”
