One, the importance of laboratory deionized ultra-pure water machine and the principle of work
1, laboratory deionized ultra-pure water machine for industrial water to implement the necessity of the second revolution.
Water usually contains five kinds of impurities:
A, electrolytes include charged particles, common cations are H +, Na +, K +, NH4 +, Mg2 +, Ca2 +, Fe3 +, Cu2 +, Mn2 +, Al3 + and so on; anions are F -, Cl -, NO3 -, HCO3 -, SO42 -, PO43 -, H2PO4 -, HSiO3-, etc.;
B, organic substances, such as: organic acids, pesticides, hydrocarbons, alcohols and esters, etc.;
C, particulate matter;
D, microorganisms;
E, dissolved gases, including: N2, O2, Cl2, H2S, CO, CO2, CH4, etc.;
The so-called purification of water is to Remove these impurities. The more thoroughly the impurities, the purer the water. Over the years, the quality of the products of many enterprises in our country, in the case of strict process management, is still unstable, and foreign products have a big gap, which is likely to be the production of water problems. If the use of deionized water, then the situation will be greatly improved, many of our industries to improve product quality, catch up with the world's advanced level of one of the important means. This, we are in practice, such as chemical, biological, spraying, surface treatment, pharmaceutical, food, electronics and other industries have been well verified.
2, with RO reverse osmosis + resin exchange method that is deionized ultra-pure water machine to achieve the possibility of industrial water (ultra-pure deionization).
Deionized water (deionized water), also known as pure water or high purity water, the traditional process is an anion and Yang bed + mixed bed, now the general process is RO reverse osmosis + mixed bed, more advanced is RO (REVERSE OSMOSIS) reverse osmosis + EDI (electrodeionization), first through the RO reverse osmosis membrane removes more than 99% of the impurities in the water (including metals), and then use this water to achieve ultra-pure deionization. Salts), and then use this water quality to do ultra-pure deionized water, this time the ion exchange resin in a solution containing a small amount of electrolyte, can be relatively complete removal of all kinds of anions and cations in the water, and the use of time and life expectancy will grow significantly, the water quality can reach a very high degree of purity. Ion exchange is an irreplaceable means of preparing high-purity water process.
As the number of ions in the deionized water can be artificially controlled, thus, making its resistivity, solubility, corrosivity, viruses and bacteria, such as physical, chemical and pathological indicators are well controlled. In industrial production and laboratory experiments, if the process involving the use of water are used in the use of deionized water, then, many parameters will be closer to the design or ideal data, product quality will become easy to control.
When raw water (pure water) passes through an ion exchange column, the cations in the water and the anions in the water are exchanged with the H+ ions of the cation resin and the OH- ions of the anion resin in the exchange column for the purpose of desalination. Different combinations of cation and anion mixed columns can make the water quality reach higher requirements.
Two, deionization water purifier function description:
1, online detection and display of ultrapure water resistivity (MΩ?cm).
2, a machine for dual-use, can be taken at the same time three levels of water and pure water / ultra-pure water, water quality and water quantity can be upgraded;
3, the product small integrated, modular, quick-connect internal design, easy to install and maintain, covers an area of small, beautiful appearance;
4, the use of imported mute pump, the system operates without vibration, no noise, no electromagnetic radiation, the working environment has no impact on the working environment?
5, the U.S. high-capacity resin depth polishing purification processing technology, to improve the total exchange volume of the ion exchange system, to extend the life of consumables;
6, digital LCD water quality display, full automation of the water system, water or water pressure is not enough, the system is automatically disconnected to protect the audio-visual alarm at the same time, multiple security protections;
7, dynamic instructions: power supply instructions, the system self-check instructions, the pump starts instructions, RO automatic flushing instructions, the pump starts instructions, the pump starts instructions, the pump starts instructions, the pump starts instructions, the pump starts the pump. RO automatic flushing instructions, water shortage protection instructions, water shortage alarm instructions, pure water standby instructions;
8, fully automated unattended design: water shortage and water shutdown system automatically shut down to protect the water pressure returns to normal when the system automatically resumes the water state; pure water standby system automatically shut down when the system automatically resumes the water state when a certain amount of pure water is taken;
9, microcomputer intelligent Microcomputer intelligent control system, RO membrane anti-scaling program and perfect automatic cleaning and disinfection program;
10, fashionable appearance: the use of high-grade ABS material open membrane finishing, exquisite craftsmanship, smooth and exquisite lines.
Three, product quality stabilization
Important parts imported, materials in line with the U.S. NSF and the Water Quality Association standards;
Standardized modular design and production, so that the product repair and maintenance is more secure;
Simulation of pre-factory debugging, so that the equipment is more suitable for the customer's operating environment;
The real-time monitoring of the quality of the produced water to achieve the national laboratory water standards and electronic water quality monitoring. Reach the national laboratory level water standards and electronic level water standards.
Fourth, low operating costs
Automatic cleaning of the pretreatment device, without the need to frequently disassemble and replace the pretreatment cartridge, reducing labor costs and consumables;
Large exchange volume of the purification column design, more resin loading, the total amount of purified water exchange is greater, to prolong the service life of the purification column;
The resin can be repeatedly regenerated and used to reduce the cost of production.
