Ecological Systems and Devices Annotation << Back Simultaneous mass exchanged water treating from rigidity and iron ions A.B. Golovanchikov, M.Yu. Efremov, N.A. Dulkina The design procedure ion-exchanging columns with a motionless ionite layer at simultaneous water treating from ions of rigidity Ca+2, Mg+2 and gland Fe+2 is offered. The developed algorithm of calculation allows to move to the resulted concentration on each ion at simultaneous ion-exchanging water treating from ions of various substances to pass to, considering their influence on local degree of using of ionite exchange capacity. To define values of motive power of process mass carry, to time a running cycle considering limiting admissible concentration in cleared water on any ion on an exit from a motionless ionite layer, and also the general degree of use of its exchange capacity. Key words: ionite; a motionless layer; simultaneous ion-exchanging water treating; running cycle time; motive power of mass carry process; the resulted concentration; degree of use of exchange capacity.
