ABSTRACT

The paper delivers and comments upon expanded (including individual parameters of fer-roparticles filtration magnetophoresis in a granular matrix) alternatives of expressions suitable for cal-culating the resulting parameter of magnetophoresis efficiency ψ as a relative reduction of ferroparti-cles initial concentration in the medium filtered. For this purpose, we employ a well-reputed model of a matrix as an exponential ferroparticles absorbing screen the application of which in the expression for ψ is justified with the account for real diagnostics of the share λ of magneto-active fraction of par-ticles entering magnetic separation zone. The paper demonstrates that alongside with acknowledged resulting parameter ψ it is reasonable to use another parameter, more convenient for testing the data, the so-called ξ-parameter as a logarithm of ψ-parameter deficit (with the account for value λ). We pay special attention to discussing the character of impact on ξ (and ψ) of such parameters as the filter-matrix granules diameter, magnetized field intensity and average induction in the matrix, matrix (chips) packing density, and initial concentration of ferroparticles.
