How to change the industry EDI deionized water and poor water quality, water quantity article of equipment: With the improvement of people's living standards, the requirements for industrial use is also increasing, industrial applications EDI deionized water treatment equipment will more and more, industrial EDI deionized water treatment equipment may have some problems during the long-term application. Through the various faults reported by some users, environmental protection will answer for everyone. Today I will first introduce to you the industrial EDI deionized water treatment equipment with high pressure and low water production. what is the reason. 1. The inlet water conductance (or TDS) is much higher than the design value. For each increase of 1000 ppm in the TDS of the NaCl solution, the osmotic pressure will increase by about 11.4 psi (0.8 bar). Under the same inlet pressure, the water production will decrease. 2. Before the membrane element is installed in the system, it is not confirmed whether the inlet water meets the standard, resulting in immersion and flushing of the membrane element with influent water containing cationic, neutral, amphoteric surfactants, or other chemicals that are incompatible with the membrane, resulting in the amount of membrane elements Decrease, the water output of the system decreases. 3. The inlet temperature of industrial EDI deionized water treatment equipment is lower than the initial design, and the water output will be reduced by 10% for every 3°C drop in inlet temperature. 4. There is an error in the reading of the instrument, the pressure gauge and flowmeter are not calibrated before use, and the reading is incorrect; or the pressure gauge is installed far away from the two ends of the pressure vessel, and its reading contains the pressure loss of the pipeline, but it is regarded as the inlet pressure This leads to low water inlet pressure and low water production. 5. Under the same inlet pressure, due to the holding pressure set on the water production side or the water production pipeline is too small and the delivery point is long and high, the resistance is large, resulting in a decrease in net pressure and a decrease in water production. 6. Under normal circumstances, the pressure difference between the two ends of the pure water equipment is about 3-4 bar, and the unreasonable pipeline design leads to a large pressure loss or the second-stage concentrated water discharge valve does not close, which will lead to a decrease in net pressure and result in water production. cut back. The water purification effect of pure water equipment does not meet the requirements, so what is the reason for the poor water purification effect of industrial EDI deionized water treatment equipment? 1. In terms of ash removal system. If there is an error in this joint section. No matter what kind of production process you use, the water produced will not meet the standard. This is a key factor affecting the effect. 2. In terms of operating procedures, water purification equipment purifies water in accordance with certain requirements. It is aimed at certain macromolecular substances or ions contained in water, and the requirements may be different under different use conditions in different industries. This is also a key factor affecting the effect. 3. In the end, the water must be produced with higher purity and higher requirements, so that it can produce water that meets the requirements, and the external environment may not always keep the water in a clean state. After the water is produced, it is likely to be used as dirty equipment and affect the quality of the produced water. The above is the introduction of the environmental protection editor on the reasons for the poor water purification effect of industrial EDI deionized water treatment equipment and the reasons for the high pressure and reduced water yield. People use industrial EDI deionized water treatment equipment mainly to improve the water quality of the water. If the water quality If the requirements are not met, there is no need for installation. Therefore, when using industrial EDI deionized water treatment equipment, you must ensure that the water quality is normal.
