What is the "laboratory" ultrapure water machine?
The traditional laboratory water in China, which is produced by distillers or used by ion exchange devices, has different degrees of problems. The emergence of ultra-pure water machine in the laboratory is a revolution in the laboratory, which allows the majority of laboratory personnel to get rid of the backward water production method in the past.
China is the first enterprise to develop, design and produce ultra-pure water machines, and the pioneer of ultra-pure water machines with tap water as the source of water. With its strong R&D strength and top ultra-pure water manufacturing technology, the company has customized six series of ultra-pure water machine system product series for Chinese users, which can provide perfect solutions for users at all levels.
The ultra-pure water machine adopts four major steps of pretreatment, reverse osmosis technology and ultra-purification treatment, including multi-stage filtration, high-performance ion exchange unit, patented special deep desalting device (EDI), ultrafiltration filter, ultraviolet lamp, TOC removal device and other treatment methods to ensure high-quality effluent quality. The products are widely used in universities, scientific research, pharmaceutical plants, power, electronics, medical treatment, disease control, environmental supervision, technical supervision and other key industries.
In order to make the user operate conveniently in the process of using, the operation control of the ultrapure water machine uses the microcomputer chip programmed control. Man-machine touch interface intelligent control, automatic water generation and shutdown, system protection and alarm indication; RO membrane automatic flushing, pure water standby indication; Separate water supply; Water quality online detection display; Quantitative water intake switch, etc.
2. What is the difference between "laboratory" ultrapure water machine and "distiller" and ion exchange device?
The traditional laboratory water in China, which is produced by distillers or used by ion exchange devices, has different degrees of problems. The distiller consumes water and electricity, which will come down in a year. Water and electricity costs nearly 10000 yuan, and labor costs are consumed. All laboratory leaders are eager to get rid of the water in more distillers. If it was the ion exchange equipment in the past, it would need a room to install the equipment, and the resin would be regenerated every week, which is also a very troublesome matter. In many places, the teacher in charge of resin regeneration was unwilling to do it and made a fuss. Later, many laboratories simply went to buy water, but it was often difficult to buy water and transport it, and the water quality was not guaranteed after being stored for a long time.
3. How to select the ultra-pure water machine correctly?
It is very important to choose an ultrapure water machine that precedes you.
The selection of ultra-pure water machine is based on the following factors: your experiment purpose (name of the experiment project), water quality demand, water quantity demand, source water quality, as well as your requirements for water intake method, installation and placement, and product appearance. According to the above requirements, choose a more suitable ultra-pure water machine for you, which will not only bring convenience to your experiment work but also save your worry.
Purpose:
According to its purpose, such as experimental items, we can roughly determine which type of model to choose (P, U, C)
Water Quality:
If there are specific water quality requirements, which type of model, such as JY, FZ, WL, can be selected for the source water quality:
The source water is yellow and has high hardness. The TDS value of the source water is high, that is, the salt content is high. Additional optional accessories are required.
Peak water consumption:
The capacity of water storage device can be selected according to peak water management
Water intake mode:
Whether the outlet pressure is required (as the inlet pressure of other instruments); Whether it is connected with the hose to take water, whether it is necessary to take a large amount of water quickly, etc
Installation and placement requirements:
Placement space, water inlet, distance of the vertical opening, and the allowable placement of the water storage tank and the host machine Other requirements:
Special needs, tailor-made
4. What does the selection of ultra-pure water function bring to you?
As an excellent science and technology expert, you adhere to a rigorous working attitude and persistently pursue the perfection of every link in the experiment, but the water production speed of the older generation of distillers is too slow, and the potential safety hazards are always worrying;
The acid and alkali regeneration of deionized water equipment and the trouble of moving a large amount of bottled water make you lose a lot of valuable time in complicated details;
The operation of water making equipment is unstable, and the experimental results are affected by water quality? Are you worried about~~~~? And worry? And sleepless all night?
Choose to use the ultrapure water machine, so that you don't have to worry about the above problems, so that your work is handy, convenient and time-saving.
5. Why should "deep desalting treatment technology" be used in the north?
Because most other areas in the north use groundwater, which is formed by the infiltration and flow of rainwater through soil and stratum. During its long flow and extensive contact, more salt is dissolved, so the groundwater has a high salt content and high hardness. In order to ensure the water quality, the pure water equipment used in the northern region needs to use "deep desalting treatment technology".
6. What should be paid attention to when using tap water as source water?
A. The water quality of tap water must meet the requirements of the Code for Domestic Water;
B. The water supply pressure of tap water is 0. 2~0。 4MPA；
C. The water temperature of tap water is 5~30 ℃;
D. Active carbon filter must be installed for the pretreatment of ultrapure water machine;
E. When the hardness of tap water is greater than 200PPM, a water softener must be installed;
F. In case of high iron and manganese content in tap water, manganese sand filter must be installed.
7. What is the working principle of EDI continuous current deionization technology?
EDI membrane block is mainly composed of alternately arranged cation exchange membrane and anion exchange membrane, thick and thin chamber separators, ion exchange resin, positive and negative electrodes, clamping device, etc., and two electrode chambers are respectively set at the positive and negative electrodes. The DC voltage of the module is provided by the EDI power supply. When the EDI membrane block is working, the internal exchange membrane only allows the ions with appropriate charges to pass through, and the water can not pass through basically. In the electric field, the water molecules in the feed water are separated into H+and OH -, H+moves to the cathode direction through the cation resin, and OH - moves to the anode direction through the anion resin. This migration of H+and OH - regenerates the resin. The flow of water in the concentrated water chamber will take away the anions and cations transferred from the fresh water chamber. The exchange membrane will prevent the ions with opposite charges from entering the fresh water chamber. In the process of water flow through the fresh water chamber, the ions in the water will be removed by the resin, so the effective side of the membrane (fresh water chamber) will produce pure water.
8. What is the central ultrapure water system of the laboratory?
The water is produced from a super pure water surface, which can supply pure water of different quality at the same time to meet the needs of many terminal water points. The central ultra-pure water system uses a centralized host to produce ultra-pure water, and then it is transported to each use point through a special ultra-pure water pipeline in a "serpentine circulation" way. Users can easily take ultra-pure water directly from the ultra-pure tap at the use point, and the number of terminal water intake points can be up to hundreds. The "serpentine circulation" transmission mode can effectively ensure that the water quality in the pipeline will not produce "stagnant water" phenomenon and ensure the circulating water quality.
