Abstract
In this research ,the regeneration process of the positive ionic exchangers (positive resins) was carried out by the use of (HCl) at various concentrations and forms . Laboratory results showed a large improvement in the efficiency ( i.e the operating time is increased from 12 to 39 hours ). However various mixtures of HCl and H2SO4 are used in order to eliminate the formation of calcium and magnesium sulfate which are formed when H2SO4 is used alone .
