*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.*
