MODELING METHODOLOGY OF EXCHANGING DIFFERENTLY CHARGED IONS IN WATER TREATMENT

The features of complex calculations, which are revealed, will help teachers and students implement the proposed methodology in the educational process. The mathematical models of statics and dynamics for exchanging ions from bi-charged to singly-charged and methods for their solution in MathCAD are proposed. Equation of the initial distribution of concentration along the filter is reasoned. The method of characteristics is adapted for analysis of the distribution of bi-charged ions in a filter. The model, which is proposed, provides varying technological and design parameters as input data in order to estimate their effect on the exchange process quality.
