What is the difference between 100 microns and 40 microns in the filtration accuracy of the pre wate

There is no essential difference, the only difference is that the 40 micron one is easier to plug than the 100 micron one, the problem is that during the service life, neither will be blocked! The installation of the pre-water purifier has a long life and is cost-effective. It can protect and extend the PP cotton of the terminal water purifier.

or other first-stage filter elements. Some of the better pre-water purifiers will basically have much better water quality after filtration, such as the Ledsi-level pre-filter.

Basically, most of the water impurities (such as rust, aquatic animals and plants, residues, etc.) can be filtered out in the first line of defense, which is the first barrier protection for household water. And the most important one.

The filter is mainly to filter the sediment, rust, red nematodes, etc. in the water, because many of them are high-rise buildings now, all need to do secondary pressurization, basically every community has a reservoir, the water in the reservoir for a long time will produce some organisms (such as red worms) or plants (such as mosses), there will be some small animals (such as rodents) into it, 100 microns may not be able to filter out some subtle impurities, 40 micron filtration accuracy is too dense, if it is not convenient to clean, it will affect the water flow! My home is equipped with a no-dismantling pre-filter with a brush, which is very convenient to clean, you can check the pre-filter of the brand of Wanshirong on the Internet, I hope it will help you.

40 microns, 100 microns indicate the smallest solid impurities that can be filtered. Particles smaller than this size cannot be filtered and will pass through directly. It can be simply understood as the size of the mesh, and what is smaller than the mesh will leak through, and what is larger than the mesh will be blocked and left.

The pre-water purifier is a part of the water purifier, which is generally installed at the front end of the pipeline, and the filtration can effectively filter out the sediment, rust, bacteria, colloid, macromolecular organic matter and other harmful substances in the water, retain the minerals and trace elements that are beneficial to the human body, and the purified water quality meets the national drinking water standard.

The pre-water purifier plays a positive role in protecting the downstream pipelines, water purifiers, water heaters, washing machines, and high-end faucets.

The above content reference: Encyclopedia - pre-water filter.

100 microns 1 micron: Filters only visible to the naked eye. We call this a pre-filter.

Micron: The above can be filtered, and macromolecular minerals can also be filtered, some bacteria, viruses, and colloids. Objects that cannot remove small molecules, such as salts and fertilizers, are mostly filtered using ultrafiltration technology.

Microns: Filters any currently known solids other than water. The produced water is pure water. This type of technology is nanofiltration or reverse osmosis. It is widely used in bottled purified water.

Hello, dear, the filtration accuracy is actually the pore size of the filter element of the filter; The size of the maximum particle that a solution containing impurities is allowed to pass through as it passes through the filter.

The size of the maximum particle allowed to pass through 40 microns is smaller than the size of the maximum particle allowed to pass through at 100 microns. It can filter visible objects such as rusty sand.

The pre-water purifier is a part of the water purifier, which is generally installed at the front end of the pipeline, which can effectively filter out harmful substances such as sediment, rust, bacteria, colloids, macromolecular organic matter in the water, retain minerals and trace elements that are beneficial to the human body, and the purified water quality meets the national drinking water standard.

The main difference between 50 microns and 100 microns for pre-mounted water purifiers is that the size of the maximum particle that 50 microns are allowed to pass through is smaller than the maximum size particle that is allowed to pass through 100 microns. The filtration accuracy is marked in microns, which indicates the filtration performance of the filter. Measurement of filtration efficiency (or filtration ratio) and formation of filtration.

The filtration degree of the filter is usually referred to as the nominal filtration degree.

Water purifier, also known as water purifier and water purifier, is a water treatment equipment that carries out deep filtration and purification of water quality according to the requirements of water use. The water purifier that we usually talk about generally refers to a small purifier used for home use. The core of its technology is the filter membrane in the filter element device, and the main technology is ultrafiltration membrane, RO reverse osmosis membrane, and nanofiltration membrane.

Precautions for the use of water purifiers:

1. Choose a suitable location during installation. To install a household water purifier, we must first choose a suitable location, and the choice of installation location shall be subject to the original tap water pipeline, and at the same time consider whether it is convenient to use water, whether it is convenient to discharge sewage, whether it is safe to use electricity, and whether it is convenient to maintain.

2. For the first time, open the faucet, water purifier inlet, and water purifier faucets, and rinse it for about 15 minutes to flush the protective liquid in the water purifier and ensure the safety of the subsequent water quality.

3. If the water purifier is used for a long time, its water yield will gradually decrease, but the water quality is still qualified and can be used with confidence.

4. Frequent cleaning of the water purifier can effectively prolong the service life when in use, so remember to clean the water purifier regularly.

Both 50 microns and 100 microns are the same and can filter what is visible to the naked eye. We call this a pre-filter. It's just that the 50 micron level is a little smaller than the 100 micron level.

If possible, it is best to use 50 microns, which can filter out some small particles of impurities in the water, such as rust, sediment, bloodworms and colloids, etc., to improve the water quality of the household and prolong the service life of the water pipe; Protect water appliances, prevent rust and sediment from detracting from the life of household appliances, and reduce the power of water appliances; Protect showers and faucets from clogging. The pre-water purifier has high requirements for the filter screen and airtight sealing, although there are many manufacturers on the market to do the front, and the brands are also very mixed, but there are not many who really master the core technology. The kind that can really reach the level of Ledsey can reach the level of water source by filtering municipal water first, and it is even rarer.

Therefore, it is best to choose a good pre-water purifier, which is the first and most important water purification barrier.

40-100um can filter algae, plankton and large particles of sediment in hard water for the first time (about 2-4 times that of rapid quantitative filter paper), the smaller the pore size, the higher the interception accuracy, but the filtration resistance also increases. Generally, when the pre-position is less than 50um, the second filter element can be reduced to 5-10um.

The difference between 100 microns and 40 microns of filtration precision: the size of the maximum particle allowed to pass through 40 microns is smaller than the size of the maximum particle allowed to pass through 100 microns. It can filter visible objects such as rusty sand.

Filtration accuracy: in fact, it is the pore size of the filter element of the filter; The size of the maximum particle that a solution containing impurities is allowed to pass through as it passes through the filter.

The filtration accuracy is different: the maximum particle size for a 100 micron filtration is 100 microns, while the maximum particle size for a 40 micron filtration is less than 100 microns.

The application scenarios are different: 100 microns is suitable for filtering visible objects such as rust sand, while 40 microns is suitable for filtering fine particles, such as sediment, bloodworms, etc.

The filtration effect is different: the water quality after 100 micron filtration is better, while the water quality after 40 micron filtration is worse than the world.

Summary. Dear, for you to provide additional information.

1. The pre-filter is the first coarse filtration equipment for the whole house water, which can filter sediment, rust and large particulate matter in tap water. The pre-filter is generally installed at the front end of the pipe, so to:"Front-loaded"two words to name; While"Filtering", which refers to the basic principles of this type of device. Usually"t"type of structure.

above"One horizontal"The left and right ends of the position are respectively the water inlet and outlet. Below"One vertical"The position is the body and the internal cylindrical filter, and the bottom is the sewage outlet, which is controlled by a valve to open and close.

2. The accuracy range of the filter varies from 5 to 300 microns according to different brands and models. It mainly removes the precipitated impurities and bacteria, microbial debris, rust, sand and mud and other particle impurities larger than 5 microns generated by the pipeline to avoid damage to the human body and skin; And it plays a positive role in protecting downstream pipelines, water purifiers, water heaters, washing machines, high-end faucets, and showers, and pre-filters can also be added"Hydrochloric acid phosphorosis"The antiscaling filter element plays a role in inhibiting scale for solar energy and water boilers.

Which is better, 40 micron or 90 micron pre-filter.

Dear, hello 40 microns, the purpose of the pre-filter is to prolong the service life of the back filter, the higher the filtration precision of the pre-filter, the greater the protection of the back filter, but the accuracy is too high will increase the frequency of replacement and increase the cost! High filtration accuracy of 40 microns.

Pro, to provide you with extended information 1, the pre-filter is the first coarse filtration equipment for the whole house water, which can filter sediment, rust and large particles in tap water. The pre-filter is generally installed at the front end of the pipe, so to:"Front-loaded"two words to name; While"Filtering", which refers to the basic principles of this type of device. Usually"t"type of structure.

above"One horizontal"The left and right ends of the position are respectively the water inlet and outlet. Below"One vertical"The position is the body and the internal cylindrical filter, and the bottom is the sewage outlet, which is controlled by a valve to open and close. 2. The accuracy range of the filter varies from 5 to 300 microns according to different brands and models.

It mainly removes the precipitated impurities and bacteria, microbial debris, rust, sand and mud and other particle impurities larger than 5 microns generated by the pipeline to avoid damage to the human body and skin; And it plays a positive role in protecting downstream pipelines, water purifiers, water heaters, washing machines, high-end faucets, and showers, and pre-filters can also be added"Hydrochloric acid phosphorosis"The antiscaling filter element plays a role in inhibiting scale for solar energy and water boilers.

3.It is usually installed behind the water meter of the inlet pipe to ensure that a large number of precipitated impurities generated in the pipe network will not cause harm to the human body, and play a positive role in protecting the hidden pipes, faucets, electrical appliances, etc. The pre-filter is the nemesis of secondary pollution and is a reliable impurity filtration device.

Good evening, 20um as a general filtration of ordinary tap water and deep well water pre-component has been able to achieve a very good effect, can remove sediment and bacteria and algae, its minimum pore size and medium speed quantitative filter paper is similar, two pure physical filtration when 20um + 1-5um post-water can meet the basic water purification requirements. The larger the pore size of the membrane, the longer the service life, and the less likely it is to burst due to increased pressure in the cold winter.

The pre-filter is important.

Due to the quality of tap water and secondary pollution, there will be various impurities such as fine particles and colloids of different sizes in the water.

After these impurities of tap water enter the household pipe network, it will not only affect the health of the human body, but also cause harm to various equipment in the home (water heaters, floor heating, washing machines, etc.) and reduce the efficiency of the equipment.

Therefore, it is necessary to install a pre-filter (primary filtration) on the inlet manifold.

For example, the German ** legislation of 1988 (DIN 1988) stipulates that buildings built after that must be equipped with protective impurity filters, which are pre-filters.

Second, the type and performance of the pre-filter.

1. Do not change the filter element.

**High, most of the filter screens are made of metal, the filter pore size is mostly between 40-90 microns (the visible impurities are more than 50 microns), and the installation site needs to have a sewage outlet.

Pros and cons: The one-time investment is larger, there is no cost of consumables in the later stage, and the treatment effect is average.

2. Change the filter element.

**Low, the filter screen is a non-metallic filter, mostly made of PP cotton (or a combination of PP cotton and activated carbon), and the installation location can be behind the water meter of the inlet main and other water points.

Most of the filter pore sizes of the filter elements are between 5 and 20 microns, and there is no need for a sewage outlet at the installation site.

Pros and cons: The one-time investment is smaller, and the replacement cost of the filter element is required in the later stage, and the treatment effect is better.

3. Other functions of the pre-filter of the filter element.

Due to its small pore size, it can also be used as a primary filter and can be installed wherever it is needed.

This pre-filter not only removes particulate impurities from the water and protects subsequent equipment, but can also be used as a filter (microfiltration) in many places where the requirements are not very high.

The minimum pore size of the filter element can reach 1 micron, which greatly improves the sensory quality of the water quality.

Once you understand the above roles, it is easy to make the right choice according to your specific situation and requirements.

Fourth, two important tips.

1. If the inlet water quality is good, for families with general water environment requirements, the use of replacement pre-filter (the filter element is a small pore size or combined filter element) is a cost-effective choice, because this kind of pre-filter can also play the role of microfiltration.

2. For water sources with poor water quality (impurities in the water below 50 microns), the non-replacement pre-filter basically has no effect.
