EDI Ultrapure water equipment principle and operation method

Ultrapure water equipment adopts advanced reverse osmosis membrane water treatment technology and mature ion exchange water treatment technology, which is an irreplaceable means in the current process of producing high purity water. Ultrapure water production equipment has high water quality and can produce water without interruption. It will not produce sewage and save labor costs. It is deeply loved by industrial production enterprises. Edi system in Ultrapure water production equipment is applicable to water treatment industry, electronic industry, Ultrapure water in laboratory, Ultrapure water system in hospital and other industries. Nowadays, more and more industrial production processes are inseparable from industrial edi Ultrapure water equipment.

1、 The principle of industrial edi ultra pure water equipment

1. The RO produced water enters the edi module and is evenly distributed into the fresh water chamber.

2. The trace ions that have not been removed from the RO membrane are adsorbed on the membrane surface by ion exchange resins in the fresh water chamber.

3. Direct current is applied to the electrodes at both ends of the edi module, driving the anions and cations in the fresh water chamber to migrate to the corresponding electrodes to the concentrated water chamber, thereby producing high-purity water.

4. Under the action of an electric field, water molecules are extensively ionized into H+and OH -, thereby continuously regenerating ion exchange resins.

2、 Operation method of industrial edi Ultrapure water equipment

1. When the industrial edi Ultrapure water equipment fails, please immediately close the tap water inlet valve, cut off the water inlet of the water purifier, and do not disassemble it by yourself.

2. When the tap water is cut off, please first open the sewage tap to drain all sediment, rust, and other debris from the tap water pipe, and then open the purification tap to use clean water.

3. The total water yield of industrial edi Ultrapure water equipment is related to the quality of incoming water. If the quality of incoming water of industrial edi Ultrapure water equipment is good, the total water yield will rise; otherwise, if the quality of incoming water is poor, the total water yield will fall, and the service life of the corresponding filter element will be slightly shorter. 

4. If the industrial edi Ultrapure water equipment is not used for more than three days, the industrial pure water equipment shall be repeatedly flushed for 2-5 minutes when it is used again until the water stored in the industrial edi Ultrapure water equipment is drained.

5. With the long-term use of industrial edi Ultrapure water equipment, its water production will gradually decline, but the water quality is still qualified, so it can be used with confidence.

6. After use, the ultrafiltration membrane filter element should always be kept moist. If the ultrafiltration membrane filter element dries, it will cause a sharp decrease in water production and cannot be restored.

7. Compatibility between agents should be considered, followed by compatibility between agents and membrane materials. For example, in RO systems, coagulants, coagulants, fungicides, reducers, and scale inhibitors are often used simultaneously. Due to the fact that limbs in natural water generally carry negative charges, cationic coagulants with positive charges are usually used.

3、 Characteristics of industrial edi Ultrapure water equipment

1. The voltage stabilization range is wide, and the input voltage can still be used normally with a change of ± 20%.

2. High efficiency, the product has a power factor correction circuit, and the power factor can reach 0.98 or above.

3. The output voltage and current are continuously adjustable, and the voltage and current are automatically switched.

4. The steady current variation of the load from small to large is less than 0.1%.

5. High safety performance, the output terminal can be arbitrarily short circuited without causing machine damage, and the short circuiting current can be continuously adjusted.

6. Adopting advanced high-frequency pulse width modulation technology, it has the characteristics of strong stability, high accuracy, small size, light weight, and low power consumption.
