What are the characteristics of condensed water desalination treatment in Dongguan Water Treatment?
It takes a period of debugging for the electrodialyzer to work out the best operating parameters, which has a great bearing on the realization of stable and long-term operation. What are the main parameters of the characteristics of condensed water desalination treatment in Dongguan water treatment.
1. Current and voltage: The electrodialyzer uses the potential difference as the driving force for desalination, and a certain DC voltage must be controlled to obtain a certain working current. The working current should be lower than the limit current. The working current is high, which helps to improve the efficiency of the equipment; the working current drops, which is good for preventing polarization.
2. Flow rate and pressure: What are the characteristics of the condensed water desalination treatment in Dongguan Water Treatment that will have better flow rate and pressure. The electrodialyzer has a certain rated flow, which cannot be too large or too small. If it is too large, the water inlet pressure will be too high, and leakage and deformation of the device will occur. If it is too small, the suspended solids will adhere to the electrodialyzer, causing the pressure of the water flow to rise, the salt removal rate to decrease, and the dead angle of the water flow and local polarization and fouling. Therefore, the linear velocity of water flowing through the pipeline is controlled at 50-200mm/s.
3. Inverted pole and pickling: Inverted pole is to replace the anode and cathode of the electrodialyzer in operation in order to eliminate polarized precipitation. What are the characteristics of condensed water desalination treatment in Dongguan Water Treatment? The time interval between polarity reversal and pickling is determined according to debugging and operating conditions. Only when the water quality and temperature change, the interval period can be changed according to the specific situation.
