摘要：

The paper considers a mathematical model for the filtration of a monodisperse suspension in a homogeneous porous medium, which consists of a mass balance equation for suspended particles and a kinetic equation for deposited particles. The multistage deposition kinetics is considered. An inverse problem was posed and numerically solved to determine the kinetic parameters in two stages of the kinetics of deposition. For this, a modified identification method was used. Results show that in the case of initial approximations away from the equilibrium point, the number of iterations increases, but the coefficients are recovered with satisfactorily errors.
