RO reverse osmosis membrane is the core part of pure water equipment. A good reverse osmosis membrane is the key to good equipment. Your customers may have questions. What kind of RO reverse osmosis membrane is a good membrane when purchasing pure water equipment? Reverse Osmosis Systems Supplier(KOKOELECTRIC) to teach you to judge.
First of all, high-quality reverse osmosis membrane products should meet these three points:
1. The higher the desalting rate and water flux of the reverse osmosis membrane, the better.
2. The oxidation resistance and hydrolysis resistance of the membrane, i.e. good physical, chemical and microbial erosion resistance;
3. The film has good heat resistance and pressure resistance.
At the same time, high-quality reverse osmosis membrane products should have the following characteristics:
1. High-efficiency desalination rate at high flow rate;
2. has high mechanical strength and service life;
3. Able to function under lower operating pressure;
4. Able to withstand chemical or biochemical effects;
5. It is less affected by pH value, temperature, and other factors.
6. The diaphragm has convenient raw material sources, simple processing procedures, and low overall cost.
Nowadays, the use of pure water treatment equipment in the water treatment industry is closely related to our domestic water. With the development of people's lives, the operation and performance quality of its equipment has effectively improved the technological competition among water treatment industries. And has promoted the popularization and operation of domestic conventional membrane treatment technology. After a period of use, does the reverse osmosis membrane need to be cleaned and replaced? The Reverse Osmosis Systems Manufacturer(KOKOELECTRIC) will tell you.
In the normal use process, the domestic conventional reverse osmosis membrane of pure water treatment products will be contaminated by inorganic scale, colloid, microorganism, metal oxide and other substances, which will adhere to and gradually deposit on the membrane surface. After accumulation to a certain extent, it will cause the output of the reverse osmosis device of pure water equipment to drop or the desalting rate to drop, the pressure difference to rise, and even cause irreversible damage to the domestic conventional membrane. Therefore, in order to restore good water permeability and desalting performance, the reverse osmosis membrane needs to be chemically cleaned.
During the daily operation of pure water equipment, it is necessary to conduct scheduled inspections and replace the precision filter element in time to prevent particle pollution of reverse osmosis membrane caused by leakage of filter element due to installation or quality problems. At the same time, check whether there is gas in the precision filter frequently, and do not allow air to enter the reverse osmosis membrane. For spare or long-term shut-down precision filters, formaldehyde protection should be adopted to prevent the proliferation of bacteria.
There is also regular backwashing of filters of pure water equipment. Friction can be generated on compressed air gas during backwashing. Only when the washing water is qualified can it be put into use. Do not bring air into domestic conventional reverse osmosis membrane. The operation time of the mechanical filter should be prolonged as much as possible, thus not only reducing the impact of the switching filter on the effluent quality but also saving a large amount of backwashing water.
At present, the reverse osmosis membrane element water treatment technology basically meets our daily drinking water index, and the domestic conventional membrane can greatly reduce the cost of membrane-based water production and solve the drinking water demand in some areas. At the same time, the domestic conventional membrane can improve the quality of tap water and reach the quality standard of normal drinking water.
Many users have a question about the replacement of the Water Filter Cartridges(KOKOELECTRIC): is the water filter cartridges universal?
Water filter cartridges are an important accessory of water purifier. The quality of its material and technology and its adaptability to the water purifier determine the water purification efficiency of the water purifier. Therefore, the selection of water filter cartridges is an important step in purchasing and using the water purifier.
Generally, water purifier products are purchased, and the water filter cartridges are installed inside the machine, so the user does not need to purchase separately. However, water filter cartridges are "consumables" in water purifier products and must be replaced regularly, so many consumers want to buy water filter cartridges of other brands and different prices to adapt to the existing water purifier.
As an important water purifier accessory, there are many kinds of water filtration cartridges, including PPcotton water filtration cartridges, granular activated carbon water filtration cartridges, compressed activated carbon water filtration cartridges, hollow fiber ultrafiltration membrane water filtration cartridges, RO reverse osmosis membrane water filtration cartridges, T33 water filtration cartridges, softened resin water filtration cartridges, energy Shi Shui filtration cartridges, Maifanitum water filtration cartridges, etc. So many water purifiers have different models, sizes and materials. In addition, water filter cartridges of different water purifier brands have different design considerations in terms of process modeling and adaptability to the water purifier. Forced installation of "non-ethnic" water filter cartridges can only backfire. Therefore, the water filter cartridges of the water purifier are not universal.
The replacement of the water filter cartridges is by no means as simple as the model and size. The use area of the water filter cartridges is also limited. Generally speaking, due to the difference in water quality between the south and the north, the water filter cartridges of the water purifier is also different. In the southern market, more ultrafiltration water filtration cartridges are used, while in the northern market, more reverse osmosis water filtration cartridges are used.
We suggest that after analyzing the brand, model, size, filtering technology, filtering material, use area and other factors of the water filter cartridges of the water purifier, we can make a decision on which kind of water filter cartridges to replace.
As one of the accessories of the water purifier, the quality of the process and the adaptability of the water purifier will directly determine the water purification effect of the water purifier products and also guarantee healthy drinking water. Therefore, if the water filter needs to be replaced, it is recommended that the same type of water filter produced by the original manufacturer of the original brand should be the first choice. Different brands and models of water purifier water filter barrels are not recommended to be installed forcibly.
1. Pay attention to the cleanliness of the outside of the water dispenser with filtration, and regularly check the aging of electric wires.
2. Pay attention to scalding when fetching water because the outlet water temperature is relatively high;
3. Do not share sockets with other kinds of electrical appliances.
4. Do not use the power cord when it does not match the socket.
5. Do not bend or stretch the power cord so as not to damage it and cause a fire.
1. Regularly check at least once a year and carefully check and eliminate safety performance and other potential hidden dangers.
2. The scale on the water inlet valve, electric heating tube, and inner container shall be removed regularly to ensure the normal operation of the water dispenser with filtration. Because the trace impurities and minerals contained in the water precipitate for a long time, if it is not cleaned regularly, it will affect the quality and service life of the effluent. Care should be taken not to knock, bump, beat or use sharp, sharp metal tools to remove dirt to prevent damage to components.
3. When removing dust or dirt on the surface of the water dispenser with filtration, the power supply must be cut off and the surface must not be washed with water or other liquid. When cleaning the sewage, only when the water temperature of the water dispenser with filtration drops to the natural temperature can the water plug be unscrewed or the connected sewage valve be opened to avoid scalding.
4. Water dispenser with filtration should be started regularly and managed by special personnel.
5. If a fault or abnormal operation is found, the power supply and water source shall be cut off in time, and the certified professional and technical personnel shall be sent to the maintenance department for inspection and repair.
6. If the power cord is damaged, it must be replaced with oil-resistant and sheathed flexible cord or special components purchased from its manufacturer or from the maintenance department of our company.
7. Turn off the power supply when not in use for a long time;
8. In order to ensure the normal use of commercial drinking fountains with filtration and ensure the cleanliness of drinking fountains with filtration, filter elements shall be replaced regularly.
"The more filter layers in the Water Filter Cartridges(KOKOELECTRIC) of the water purifier, the better the filtering effect." This misconception has become a stubborn "truth" in the hearts of many consumers, so they prefer to buy water purifier products with multiple built-in water filter cartridges.
Major brands of water purifiers, of course, have to cater to this consumption trend, so water purifiers manufacturers have also taken advantage of the opportunity to expand the grade of water filter cartridges of water purifiers to grade 7, 10 or even 12. If this trend continues to spread, it is believed that there may be 16 or even 20 grades of water purifiers in the near future.
As we all know, the core function of the water purifier is mainly realized by the water filter cartridges of the water purifier. Although there are dozens of accessories for the water purifier, it is the water filter cartridges of the water purifier that really plays the role of purifying water. However, this does not mean that the greater the number of water filter cartridges in the water purifier, the better the water purification effect will be.
The key judgment standard is not a few grades, but the raw materials and filtering dimensional accuracy of the water filter cartridges of the water purifier. The quality of a product is essentially determined by its raw materials and production process. However, under normal circumstances, the value of the product is often kidnapped by the brand value.
In the market, many inferior water purifier products do not meet the standard techniques, and a layer of carbon powder in the filter layer will be discharged along with the water flow and mixed into drinking water to cause secondary pollution. In order to prevent this kind of secondary pollution, a layer of filtered carbon powder should be added. In this way, although the filter layers seem to become many, considering from the side, the extra layers have no substantial effect on water purification.
Whether the water filter cartridges of a water purifier meets or even exceeds the standard depends on the diameter of the water filter cartridges. At present, the diameter of the water filter cartridges that can be seen on the market can reach as small as 0.01 micron. With such dimensional accuracy, tap water only needs to be filtered once.
In other words, if a water purifier has ten water filter cartridges with a diameter far greater than 0.01 micron, it is not as thorough as a water filter cartridges with a standard of 0.01 micron.
In order to ensure the safety of drinking water, people buy water dispenser with filtration one after another, but many people find that wastewater is discharged after buying water dispenser with filtration, so they wonder why Water Dispenser With Filtration(KOKOELECTRIC) discharge wastewater at work? Will it affect water quality?
1. Return the wastewater to the inlet end of the water dispenser with filtration.
The process of reverse osmosis water production is actually a process of concentration. In the process of water production, the concentrated salt in the system must be drained to maintain the stability of the system. If the wastewater from the water dispenser with filtration is returned to the water inlet end of the water dispenser with filtration, this means that for the water dispenser with filtration, only salt flows in and no salt is removed, and the salt content of the water in the water dispenser with filtration will increase rapidly, eventually causing the osmotic pressure of the water to exceed the pressure provided by the booster pump, resulting in the water dispenser with filtration not producing water. At the same time, due to the increase of salt content, some insoluble minerals begin to deposit on the surface of the membrane, resulting in blockage and damage of the reverse osmosis membrane. This damage is usually irreversible and only the reverse osmosis membrane can be replaced.
2. Regular intermittent discharge of wastewater
There are many such products on the market. Water dispenser with filtration work for several minutes and discharge wastewater for tens of seconds. This method is also undesirable. The recovery rate of the reverse osmosis membrane is 100% during the period when the water dispenser with filtration does not discharge wastewater. At present, no reverse osmosis membrane in the world can achieve a recovery rate of 100%. As a result of such use, trace insoluble salts in water are rapidly deposited on the surface of the membrane, which leads to reverse osmosis blockage and severely shortens the service life of the reverse osmosis membrane. For this type of machine, users usually have to replace the reverse osmosis membrane within 6 months, while for a reasonable system, the service life of reverse osmosis is usually about 3 years.
3. Store the wastewater for other purposes.
This method is to use a large pressure barrel to store the wastewater and then release it for use when needed. This method is the only feasible method at present because it does not substantially change the operating parameters of the water dispenser with filtration.
Through the above introduction, I believe you will find that the wastewater produced by the water dispenser with filtration is a normal phenomenon, you need not panic, and the discharged wastewater can be used for other purposes without causing waste of resources.
When consumers buy water purifiers in shopping malls or specialty stores, they often hear salesmen say "PP Water Filter Cartridges(KOKOELECTRIC)". These terminology often makes Xiaobai users a second monk who can't figure it out. Then, PP water filter cartridges Why is this called?
In fact, the name of the PP water filter cartridges is not a hole in the wind. It is made by heating and dissolving polypropylene plastic material, and is made by hot melt entanglement of polypropylene microfiber, which is commonly known as "meltblown" molding. Since the English name of polypropylene is Polypropylene, the entire water purifier has gradually turned it into a PP water filter cartridges.
The water purifier PP water filter cartridges has high precision and good filtering effect, and can effectively remove impurities, rust and other potentially harmful substances in the tap water.
PP water filter cartridges has multi-layer deep structure, long life, no chemical adhesive, safety guard, low cost. Based on these characteristics, PP water filter cartridges is more used in household tap water purification and industrial pure water filtration.
Various types of water purifier products will use the PP water filter cartridges as the first in the water purifier water filter cartridges level, so the consumers of the three stores are often referred to by the “PP water filter cartridges”. The production focus of PP water filter cartridges products is the control of the aperture precision. In the shopping malls or specialty stores, the sales staff often throws a quality commitment with a hole diameter of 1 micron or 5 or 10 micrometers. In fact, they want to produce The 1 micron aperture precision PP water filter cartridges has very high requirements on the process technology, and the production cost is naturally low. However, according to the PP water filter cartridges produced by this precision, the water filtration effect is definitely better. .
