What are the factors affecting the operation of fully automatic stainless steel pure water treatment equipment? Author: Today's industrial production rely on automatic stainless steel water treatment equipment, but there are many factors that affect the normal operation of equipment in use, below our staff introduce you to CAUSE affect the normal operation of equipment which ? How to solve it.  1. The influence of water conductivity: Under the same operating current, as the conductivity of raw water increases, the removal rate of weak electrolyte by EDI decreases, and the conductivity of effluent water also increases. If the conductivity of the raw water is low, the content of ions is also low, and the low concentration of ions makes the electromotive force gradient formed on the surface of the resin and the membrane in the shallow chamber also large, resulting in an increase in the degree of water dissociation, an increase in the limiting current, and the generation of H+ The large amount of OH- and OH- makes the regeneration effect of the anion and cation exchange resin filled in the shallow chamber good.   2. The influence of working voltage and current: the working current increases, and the quality of the produced water keeps getting better. However, if the current is increased after increasing to the highest point, the amount of H+ and OH- ions produced by water ionization is too much. Except for the regeneration of resin, a large number of surplus ions act as current-carrying ions for conduction, and at the same time, due to the movement process of a large number of current-carrying ions Accumulation and clogging occurred in the process, and even reverse diffusion occurred, resulting in a decline in the quality of the produced water.  3. The influence of turbidity and pollution index (SDI): The water production channel of EDI module is filled with ion exchange resin. Excessive turbidity and pollution index will block the channel, causing the system to increase the pressure difference and decrease the water production. 4. The impact of hardness: If the residual hardness of the influent water in EDI is too high, it will cause the membrane surface of the concentrated water channel to scale, the concentrated water flow rate will decrease, the product water resistivity will decrease, and the product water quality will be affected, and the components will be blocked in severe cases. The water and extreme water flow channels cause the components to be destroyed due to internal heating.   5. The influence of CO2 in the influent: HCO3- generated by CO2 in the influent is a weak electrolyte, which easily penetrates the ion exchange resin layer and causes the quality of the produced water to decrease.
