An important factor in determining the quality of water produced by ultra-pure water systems is the desalination efficiency of these systems. There are many factors that affect this desalination efficiency, and one of the most important ones is the conductivity of the water entering the system. So, what impact does the conductivity of the water entering an ultra-pure water system have on its desalination efficiency? With other conditions remaining constant, the desalination efficiency deteriorates as the conductivity of the raw water increases. This is because once the conductivity of the incoming water exceeds a certain level, the operating range of the module shifts downward; eventually, the regeneration zone disappears and the operating range extends beyond its limits, causing most of the filling resin within the module to reach a saturated and non-functional state. At the same time, as the ion concentration in water increases, the current rises when the voltage remains constant; as a result, the process of ionizing water is weakened, and the amount of H+ and OH- ions produced by water ionization decreases, which directly leads to poorer regeneration of the resin. In this way, when the quality of the water entering the system deteriorates, weak electrical ions will begin to penetrate gradually through the module, and the current in the system will increase. Due to the ionization of water, at a constant voltage, the increase in current is nonlinear.
