What is water purification machine?
Water purification machine
is a kind of water purification equipment using a multi-stage filter cartridge for water purification treatment, processing more physical methods such as filtration, adsorption, and reverse osmosis without adding chemicals. According to the water purifier, water purification accuracy can be divided into two categories: drinking water purifier and laboratory water purifier that can meet the requirements of laboratory pure water quality.
Laboratory water purifier is the most commonly used water purification system in the laboratory, is through filtration, reverse osmosis, electrodialysis, ion exchanger, ultraviolet sterilization, and other methods to remove all solid impurities, salt ions, bacteria, and viruses in the water treatment device.
Application of water purification machine
The application areas of water purifiers are as follows.
|Plating||plating because of its process, to ensure the purity and uniformity of plating, the water used in the electrical solution to meet the higher requirements.
|Power plant|| The water quality of pure water used in power plants generally has to meet the standard.
|Food and beverage|| food and beverage production, processing, ingredients and other water requirements are higher than ordinary domestic water, especially for mineral impurities in the water, microbial content has strict filtration requirements.
|Pharmaceutical||pharmaceutical water requirements are strict, or even higher, using reverse osmosis equipment mostly used in EDI or polishing mixed bed to stabilize water quality, in order to reduce unnecessary depletion in the production process.
|Medical|| medical injections, dialysis, laboratory tests and other links need to use ultrapure water.
|Chemical industry|| the chemical industry has a wide range of branches, the scale is generally larger, basically will use ultrapure water, but because of the subdivision of a wide range of industries.
Water purification machine working principle
Laboratory water purification system is the use of pretreatment, reverse osmosis technology, ultra-purification treatment, and post-processing methods, the conductive media in the water are almost completely removed, but also the water is not dissociated from the colloidal substances, gases, and organic matter are removed to a very low degree of water treatment equipment.
1. Source Water Pretreatment System
The main task of the pretreatment system is to clean up these impurities to prevent structural phenomena from occurring in the reverse osmosis membrane and increase the life span of the membrane, as well as to remove impurities more efficiently.
2. Reverse osmosis system
Reverse osmosis membrane can quickly sieve out impurities in water with stable performance, and can sieve out insoluble substances in water under the pressure set by the equipment. So the equipment can precisely filter out most of the carcinogenic substances in the water. The desalination effect reaches more than 99%, and the reverse osmosis system has automatic cleaning function, which can effectively remove the blockage in the reverse osmosis membrane and ensure the continuous and efficient operation.
3. Purification column system
The nuclear-grade purification resin, in the treatment system equipment, allows the ions in the water to be removed in their entirety. The water quality of pure water produced through the system has high resistivity and also meets the requirements of some laboratory applications.
4. Ultraviolet sterilization
The UV sterilization system uses two wavelengths of UV lamps to be able to have great equipment performance at the same time. The ultra-pure water goes through a six-treatment process within the UV sterilization lamp to remove the remaining bacteria while explaining away the residual substances in the water.
5. Ultra microfiltration system
The use of terminal microfiltration technology, is through the terminal microfiltration equipment, a little higher than the usual terminal microfilter water production, greatly increasing the service life, to better ensure the output water high quality.

Precautions for using water purification machine
1. It is strictly forbidden to move laboratory water purification machine when it is working, and avoid hard objects from hitting the instrument.
2. In order to inhibit algae production, avoid using translucent water tanks and pipes, and avoid installing the water storage tank in direct sunlight or near heat sources.
3. The pure/ultrapure water produced should be used as you take it out to avoid long-term storage and the growth of bacteria. Of course, if you are equipped with a special sterile water tank, you do not have to worry about pollution.
4. In daily use, you should pay attention to the alarm prompts of the equipment and replace the consumables regularly according to the prompts and instructions of the equipment, and pay attention to regular disinfection and pipe cleaning to avoid microbial reproduction affecting the water quality.
5. After the laboratory water purification systems malfunction, please ask professional and technical personnel to deal with it. The use of components not recommended by the manufacturer may affect the performance of the instrument.
How to maintain water purification machine?
Laboratory ultrapure water machine maintenance needs to pay attention to the following aspects.
Fine cartridge, also called filter cartridge, is divided into wire-wound cartridge and PP meltblown cartridge, which mainly filters large particles such as silt in raw water, and its filtration precision is 5 microns, 1 micron and so on. The new cartridge is white, and if the appearance of the cartridge will be silt for a long time, it will be brown, which indicates that the cartridge cannot be used, and it can be used for 1-2 weeks after the appearance of silt is flushed out with tap water, but it cannot be used for a long time.
The cartridge is placed inside the filter bottle, some of which are transparent and can visually investigate the color change of the cartridge, some of which are opaque and need to be unscrewed to investigate the change of the cartridge. From the experience data statistics, the life span of the fine cartridge is generally 3-6 months, such as more sediment in the original water, the life span is shorter, and the life span of the sediment and other particulate matter is a little longer.
Activated carbon cartridge
Activated carbon cartridge removes odor and organic matter from water through adsorption effect. There is residual chlorine in tap water, which has a great oxidizing effect on the reverse osmosis membrane, so it must be removed by activated carbon. Activated carbon cartridge has no intuitive change from the appearance, according to the experience, generally in about a year to reach saturation adsorption, need to replace.
Reverse osmosis membrane
Reverse osmosis membrane is a very important part of the laboratory ultrapure water machine, its pore size is very small, so in the process of use often have bacteria and other microscopic material siltation in its appearance, the general laboratory ultrapure water machine of various manufacturers have a backflush function, designed to wash away pollutants.
The amount of water used in 10 liters / day or less, can be flushed 3-5 times, more than 10 liters, more flushing several times. If a long time (such as more than 1 month) do not have to, need to take it out soaked in disinfectant solution to avoid the growth of bacteria, but the process is more trouble, it is recommended that even if you do not have to use water, are often turned on with a small amount of water, so that the formation of water circulation inside the machine, try to reduce the deposition of dead water for too long. Reverse osmosis membrane life span in 2-3 years, the primary by the amount of water to resolve, so in the selection of the time must be selected to match the standard.
Purification column is sometimes called ultra-purification column according to the customer's water quality needs, since the effect is to reverse osmosis pure water for deep desalination, and finally reach the level of first-class water or ultra-pure water. The principle is ion exchange.
The longevity of the purification column is reflected by the resistivity online. Below a particular resistance means that the purification column is expired, which is more intuitive.
