Generally, no significant effects should be observed at temperatures between 58 and 60 degrees. However, if the temperature is too low and the temperature of the brine entering the electrolyzer is low, this will first be reflected in the cell voltage, with an increase in voltage and higher power consumption； The current efficiency decreases.

60 degrees is acceptable; 50–60 degrees represents the optimal condition. Heating is necessary before inserting it into the slot
It is acceptable for the refining temperature to be slightly below 60 degrees; too low a temperature can affect the refinement of the secondary brine. The refining effect is best when the resin is at around 60°C.
A low temperature of the brine entering the electrolyzer leads to an increase in voltage, higher power consumption, and reduced efficiency. Last edited by limingshuguang on 2009-3-20 19:02.]
The parameter provided by Asahi Kasei’s electrolyzer technology is 60±5°C; if the cell temperature is too high, the temperature of the brine fed into the cell can be reduced appropriately to adjust it. This post was last edited by limingshuguang on 2009-3-20 19:03.]
The temperature is below 60 degrees; if it’s between 55 and 58 degrees, the problem is likely not serious! If it is low, it is mainly because the adsorption rate of alkaline earth metal ions in saltwater by the resin slows down; in other words, the rate at which alkaline earth metal ions chelate with the resin slows down, as does the rate of ion diffusion. But the overall effect won’t have much of an impact. What multiple of the transfer volume is required for your resin? What is the actual operating multiple of the transfer volume? This response applies only to the resin tower, not to the electrolysis system; please feel free to point out any inaccuracies! This post was last edited by limingshuguang on 2009-3-20 19:04.]
The temperature of the brine entering the electrolyzer is primarily related to power consumption. A low temperature of the brine entering the electrolyzer leads to an increase in voltage, higher power consumption, and a decrease in current efficiency, which is detrimental to production.

Our company maintains the temperature of the water distribution tank between 55 and 65 degrees
It is advisable to keep the quality of the brine fed into the resin tower at around 60 ± 5 degrees, as this allows the resin to carry out adsorption at its optimal activity level, given that each type of resin has a different adsorption capacity. Regarding the discussion that entering the electrolytic cell increases the cell voltage and energy consumption, I think there should be another heat exchanger after the brine exits the resin tower. This is who we are!
The temperature of the brine should be between 50 and 60 degrees. Moreover, the brine sent to the electrolysis process is first stored in a concentrated brine tank before being sent there; it still needs to be heated before entering the resin tower after reaching the electrolysis unit.
I believe that in addition to its effect on resin activity, it also helps to maintain control over the tank temperature, ensuring that the membrane expands at a constant rate without any changes.
On the one hand, saltwater purification has temperature requirements; the chelating resin requires a saltwater temperature of 60 degrees； Operating the electrolyzer at low temperatures increases power consumption and raises the cell voltage. Generally, when the temperature of the electrolyzer fails to rise, steam from E-273 is used for heating, which increases steam consumption
A temperature of 60-65 is optimal; low temperatures are detrimental to the resin tower’s ability to absorb calcium and magnesium. Low temperature of the brine entering the tank results in a large temperature difference across the membrane, which causes contraction and affects its service life. If the temperature is too high, the resin is prone to damage due to the high temperature. Remember to give me extra points; I’m poor right now.
Based on actual operating conditions, appropriately reducing the preheating temperature of the brine has no impact on resin regeneration. For example, in summer, when temperatures are high, lowering the set preheating temperature of the feed brine not only reduces steam consumption but also facilitates better heat exchange between the brine and chlorine, thereby further reducing the amount of water carried along with the chlorine.
Keeping the temperature below 60 degrees has the following effects: 1. Reduces the adsorption efficiency of the resin; 2. Affects the temperature of the tank; 3. Affects the voltage in the tank; 4. Affects power consumption; 5. Affects current efficiency; 6. Affects the temperature of the dechlorinated brine at later stages; 7. Affects the free chlorine content in the brine before dechlorination
Generally, 60 degrees needs to be controlled. It depends on the resin type. Generally, for every 1-degree drop in resin temperature, the resin’s adsorption capacity decreases by 2–3%.
The negative effects of excessive low temperature include affecting the concentration and the precipitation of impurities before salt dissolution; introducing low-temperature brine into the resin tower reduces the efficiency of impurity adsorption. Additionally, feeding brine at low temperature into the tank increases power consumption, raises the tank voltage, and decreases current efficiency, which is detrimental to production.
