The mathematical model of process of the magnetic besieging of admixtures in a porous filtering nozzle which takes into account reverse influence of characteristics of process (concentrations of sediment) on the parameters of environment at the terms of variable entrance velocity was offered. The algorithm of decision of the proper nonlinear perturbative problem of type “convection-mass-transfer” was built. On this basis was conducted a computer experiment, the results of which, in particular, confirm the known fact, that the productivity of work of filter substantially depends on velocity of filtration. Within the framework of this model is foreseen an automated control of process of the besieging of admixtures in the magnetized filtering nozzle depending on a basic data of water environment and velocity of filtration.

Key words: filtration, magnetic filter, magnetic purification, model of the magnetic besieging, asymptotic upshots, nonlinear tasks, reverse influence.

Magnetically-filtration properties of composition granular nozzles of magnetic filters were investigated. It was shown that the size of middle induction in the volume of nozzle depends on correlation of the masses of granules of ferromagnetic and ferrimagnetic. The size of remaining magnetizing of composition nozzle in 2-3 times is less from the known ball-shaped nozzle. The influence of tensity of the external magnetic field on the size of coefficient of besieging was shown.

Key words: ferromagnetic nozzle, magnetic besieging, filtration.
