The EDI (Electrodeionization) module LXM30HI-3 from Siemens is a device for water treatment systems that is capable of removing ions and contaminants from water through electrochemical processes. This technology achieves high-purity water treatment through the action of ion exchange resins and electric fields without the addition of chemical agents. Below, the blue film water treatment will introduce to you the influencing factors of its water production resistivity.
There are many factors that affect the resistivity of permeate water, and here are some of the common ones:
1.Influent quality: The quality of influent water has an important impact on the resistivity of permeate water. The ionic concentration, organic matter, particulate matter, etc. in the influent water will affect the resistivity of the permeate water. The better the quality of the influent water, the higher the resistivity of the permeate water.
2.Type and state of resin: Anion-exchange resins are used in EDI systems, and the type and state of resin have a significant impact on permeate resistivity. The purity and saturation of anion and cation exchange resins affect the resistivity of permeate water. High-quality resin and good saturation can improve the resistivity of permeate water.
3.Supply voltage and current: In EDI systems, the magnitude of the supply voltage and current has a direct impact on the permeate resistivity. The higher the supply voltage and current, the faster the ion migration rate and the higher the resistivity of the permeate water.
4.The temperature of the water: The temperature of the water also has an effect on the permeate resistivity of the EDI system. In general, the lower the temperature of the water, the higher the resistivity of the produced water. Because the lower the temperature of the water, the slower the movement of water molecules, the slower the ion migration rate, thus increasing the resistivity of the produced water.
5.pH of water: The pH of water also has an effect on the permeate resistivity of the EDI system. In general, the closer the pH of the water is to 7, the higher the resistivity of the produced water. Because the pH value of water is closer to 7, the lower the concentration of ions in the water, which reduces the conductivity of the water and increases the resistivity of the produced water.
6.Operating conditions: The operating conditions of the EDI system, such as water flow rate, water temperature, pH value, etc., can also have an impact on the permeate resistivity. Reasonable operating conditions can improve the resistivity of permeate water.
7.Cleanliness of the system: The cleanliness of the EDI system also has an impact on the resistivity of the permeate water. The presence of particulate matter, organic matter, and other contaminants in the system can reduce the resistivity of the permeate water. Therefore, it is very important to regularly clean and maintain the EDI system and maintain the cleanliness of the system to improve the resistivity of the permeate water.
In conclusion, the permeate resistivity of the EDI module LXM30HI-3 from Siemens in the United States is affected by a variety of factors. In order to obtain permeate with high resistivity, it is necessary to take into account factors such as the quality of the influent water, the type and state of the resin, the voltage and current of the mains, the temperature and pH of the water, the operating conditions, and the cleanliness of the system, and take corresponding measures to optimize them. Through reasonable operation and maintenance, the EDI system can be ensured to operate stably and provide high-quality high-resistivity produced water.
