Abstract
Improvements in patent of invention no. 358.307 by "electronic device for control of ion exchange processes" apparatus in which a voltage proportional to the ratio of two resistances is provided, of which the one in one of the terms is the resistance measured between two electrodes placed in a bed of ion exchange at a short distance from the bottom of the same, through which the effluent outlet takes place, while the other contained in the remaining term is the resistance measured between two electrodes placed in a cell of insulating material filled with spent resin, a through which the untreated liquid passes before entering the ion exchange device; wherein said suitably amplified voltage serves to activate a reading instrument and to provide two signals, through the corresponding digital type circuits at two different levels, one when said voltage reaches a value corresponding to the resin in process of exhaustion, and another when the voltage reaches a value slightly lower but close to that which corresponds to the resin regenerated and free of regenerating solution; in which said signals, or the absence thereof, serves to give the alarm and/or trigger an automatic regeneration process, indicate the end of the expulsion of the regenerant, and, where appropriate, carry out the change of the provision of open and closed valves to give way to the effluent already treated, or to give the alarm in the course of an automatic process of regeneration if for any reason the regenerating solution has not penetrated into the exchanger bed, characterized in that the disposition to reproduce the resistance between electrodes of a mass of resin submerged in water, consists of two resistive branches, one composed by a resistance due to water measured between electrodes in a bucket, and the other, in parallel with the previous one, composed of a fixed resistance in series with a resistance due to water, measured in a second tank whose constant is different from that of the first.
