. Ultrapure water was originally developed by the American scientific and technological community in order to develop ultrapure materials (semiconductor original materials, nanometer fine ceramic materials, etc.) by applying distillation, deionization, reverse osmosis technology or other appropriate supercritical fine materials. Ultrapure water produced by advanced technology has now been widely used in biology, medicine, automobiles and other fields. In addition to water molecules, this kind of water has almost no impurities, and there are no bacteria, viruses, chlorine-containing dioxins and other organic matter. Of course, there are no mineral trace elements needed by the human body. Ultra-pure water has no hardness, tastes sweeter, and Often called soft water, it can be drank directly or boiled. Ultrapure water is a level that is difficult to achieve in general processes. If the resistivity of water is greater than * or close to .3*, it is called ultrapure water.

Can replace the traditional mixed ion exchange technology (B) to produce stable deionization Ionized water. Compared with mixed ion exchange technology, this technology has the following advantages:
.
. The amount of ion exchange resin used is less, which is approximately equivalent to the amount of resin used in traditional ion exchange methods.
.
.. Ion exchange resin does not require acid or alkali chemical regeneration, saving a large amount of acid, alkali and cleaning water, and greatly reducing labor intensity.
.
..No waste acid or waste alkali is discharged. It is a clean production technology and an environmentally friendly product.
.
..The process is easy to realize automatic control, and the water quality is stable. Combined with R and other water treatment technologies, it can form a complete pure water and ultrapure water production line.
.
.. The produced water quality is high and can reach the national electronic grade water level standard. The resistivity is ~, and the bacterial endotoxin content is less than./can be fully satisfied
.
. It meets the requirements for medicinal water in the Chinese Pharmacopoeia and the United States Pharmacopoeia.
.
.. It has excellent ability to remove weakly dissociated substances (such as carbon dioxide, silicon, boron, ammonia, etc.), and is more suitable for the needs of ultrapure water.
.
. .The pure water production process is continuous, and there is no need to repeatedly set up one set for regeneration like the ion exchange bed
.
. Focus on ultrapure water in China There are not many equipment manufacturers. The ultrapure water equipment produced by Huitongyuan Environmental Protection Technology is the leader in this industry. Huitongyuan cooperates with many large domestic enterprises in the pharmaceutical industry, microelectronics industry, chemical industry, etc. Among the customers are Shenzhen Huimin Pharmaceutical Co., Ltd., Shenzhen Kairuilin Technology Co., Ltd., and Dongguan Yisheng Battery Co., Ltd. Working principle
.
. The module (membrane stack) is the core of the work. A simple membrane stack is mainly composed of two electrodes with opposite electrical properties and multiple module unit pairs. A membrane unit pair consists of a fresh water chamber (chamber) filled with cation and anion exchange resin, a positive membrane, a negative membrane, It consists of a concentrated water chamber (chamber). The membrane stack contains multiple pairs of membrane units. Inside each membrane stack there are two electrodes carrying a voltage, which is the voltage necessary to pass through each membrane stack. The positive electrode carries positive voltage, the negative electrode carries negative voltage, and the current passes through the three membrane units between the positive electrode and the negative electrode. Any freshwater chamber contains cation resin and anion resin, which is equivalent to a kilometer thick mixed bed. A positive membrane separates the fresh water chamber and the concentrated water chamber toward the cathode, and on the other side, a negative membrane also separates the fresh water chamber and the concentrated water chamber. The membrane used is very different from the membrane used for reverse osmosis. The membrane used for reverse osmosis allows small particles of molecular pollutants, ions and water to pass through, while the membrane, like ion exchange resin, is made of polystyrene and only allows Appropriately charged ions pass through, but water essentially cannot pass through. The resin is continuously regenerated through water separation.
.
. In the electric field, the water molecules in the feed water are separated into + and
.
. They are attracted by opposite charges, and the + moves to the cathode through the anode resin. Direction, - the direction through which the anion resin moves toward the anode. This migration of + and - regenerates the resin, the positive membrane allows the + to pass into the concentrate chamber, the negative membrane allows the - to pass also into the concentrate chamber, the + and - combine to create the produced water . The flow of own water in the concentrated water chamber will take away the anions and cations in the water. The membrane prevents oppositely charged ions from entering the fresh water chamber. As the water flows through the fresh water chamber, the ions are removed by the resin, so pure water is produced on the active side of the membrane (fresh water chamber).
