The difference between water purifier and water softener

Water treatment equipment includes many types, including water softeners, water purifiers, and water purifiers. At the same time, they also perform their duties and each have their own specialties. Today, I will briefly introduce the water purifier and water softener. What are the differences between water purifiers and water softeners, which are also water treatment equipment, and where are their respective areas of responsibility, can they replace the existence of one party? The following explains the difference between water purifiers and water softeners in detail!

The difference between water purifier and water softener-different structure

Water purifiers can be divided into vertical ultrafiltration water purifiers and horizontal ultrafiltration water purifiers according to different installation methods. The vertical ultrafiltration water purifier is composed of PP cotton, granular activated carbon, compressed activated carbon, external pressure ultrafiltration membrane, and T33; the horizontal ultrafiltration water purifier is composed of a stainless steel shell, an internal pressure ultrafiltration membrane, and KDF. The water softener is mainly composed of: multi-way valve controller, resin tank, strong acid cation exchange resin, water distributor, salt valve, salt tank, etc. The materials and structures of water purifiers and water softeners are very different, which leads to differences in the objects and scope of their use.

The difference between a water purifier and a water softener-different uses

The water purifier is a water treatment equipment that filters bacteria and impurities in the water. The main targets for removal are: floating substances, heavy metals, bacteria, viruses, etc. As for the water softener, it is much simpler. The water softener is a water treatment equipment used to soften water. It is aimed at hard water and the target is the magnesium and calcium ions contained in the hard water.

The difference between water purifier and water softener-different working modes

The water purifier uses five-stage filtration technology to process water into water that can be used for human consumption. The five-stage filtration is: the first stage is a filter element, also known as PP cotton; the second stage is granular activated carbon; the third stage is precision compression Activated carbon; the fourth grade is reverse osmosis membrane or ultrafiltration membrane; the fifth grade is post activated carbon, mainly used to improve taste. Compared with the water purifier, the water softener also uses five processes to achieve the water purification function and soften the hard water. The five processes are divided into: work (sometimes called water production), backwash, salt absorption (regeneration), slow flushing ( Replacement), fast flushing five processes.
The above is the difference between a water purifier and a water softener. The difference between the two types of water purifiers is very big. Carry out a detailed investigation of the water quality and purchase water treatment equipment under the guidance of professionals.

How much do you know about the rumors of these water purifiers

Anyone who knows water purifiers knows that if there are too many impurities in the water, the impurities in the water will fill up the entire filter element after half a year or a year, and the water will not come out. If the filter element is not replaced at this time, the entire water will be purified The device is equivalent to scrapped. Although the current filter cartridges cost a few thousand yuan, impurities will precipitate after a long time. There is no such thing as a water purifier advertised as "no filter cartridge replacement".

Misunderstanding 1: The filter element can be used all the time

Water purifiers are different from other household appliances in general. They cannot be used once and for all after they are purchased. The internal filter elements need to be cleaned or replaced regularly. In the life cycle of the water purifier filter element, the standard of regular replacement should be strictly implemented, and the subsequent maintenance service of the filter element should be standardized. Many brands on the market have been claiming that their water purifier products do not need to replace the filter element, and even some sales deliberately do not mention replacing the filter element in front of customers. Remember that 100% of the current water purifiers on the market need to replace the filter element! They are all physical filtration methods. Think about it, all the things in the dirty water are separated or adsorbed together by the filter element. It is accumulated over time, is it terrible?

Misunderstanding 2: The more expensive the price, the better the effect

There are currently four mainstream filtration technologies for water purifiers, microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. In terms of filtration accuracy, the microfiltration water purifier belongs to ordinary filtration, and generally can only filter larger suspended solids and remove odors. The filtration effect of the ultrafiltration water purifier is in the middle. The reverse osmosis water purifier has the highest filtration precision and the best water purification effect.

However, some merchants use the ultrafiltration machine to pretend to be a reverse osmosis water purifier. Although the price is expensive, the filter element does not have the filtering effect of the reverse osmosis filter element. There are also some brand manufacturers with the same filter element and the same filtration accuracy, but the price is much higher than that of ordinary brands. Most of them are used for advertising! Therefore, consumers cannot just look at the price, and think that the expensive is good. We should weigh in many aspects so that we will not be fooled by knowing the distinction.

Misunderstanding 3: No need to change the filter if the price is expensive

Anyone who knows water purifiers knows that if there are too many impurities in the water, the impurities in the water will fill up the entire filter element after half a year or a year, and the water will not come out. If the filter element is not replaced at this time, the entire water will be purified The device is equivalent to scrapped. Although the current filter cartridges cost a few thousand yuan, impurities will precipitate after a long time. There is no such thing as a water purifier advertised as "no filter cartridge replacement".

Why do we need to install a water purifier if the tap water is qualified?

Core reminder: The after-sales service of the water purifier mainly focuses on the replacement of the filter element. If the filter element is not replaced for a long time, the water quality will be polluted, and the water purifier will become a "sewage device".
The after-sales service of the water purifier mainly focuses on the replacement of the filter element. If the filter element is not replaced for a long time, the water quality will be polluted, and the water purifier will also become a "sewage device". To choose a water purifier product, you must choose a brand with a complete after-sales service system, such as the use of the Internet of Things service system to track equipment usage, so as to promptly remind users to replace filter elements and deal with equipment failures.

Clean water is a topic that has no choice but to be mentioned frequently. The source of life, once drunk casually, now needs to be cautious.

For this reason, many families have installed water purifiers to ensure the safety of drinking water for their families. However, some people believe that the tap water at home is qualified by the water treatment plant. If the water purifier is installed again, it is a kind of repeated investment and unnecessary consumption.
Regarding this problem, users who have installed a water purifier and replaced the filter element will know that the original clean filter element is covered with yellow sand and other pollutants after a period of use. The harmful impurities that are visible and invisible are all drinkable into the body.

So where do these pollutants come from?

The first is the water pipe network. After the tap water leaves the factory, it is transported or stayed for a long distance through the water supply network, and various problems will occur when it reaches the user. Especially the long-lived tap water pipes will inevitably produce aging and corrosion problems after long-term use. The yellowing, sand, and rust problems in water quality in many areas are water pollution caused by aging water pipes.
The second is the pollution caused by the secondary water supply tower and water tank. If the water tanks of some high-rise communities have not been cleaned for a long time, they will store a large amount of contaminated impurities. Long-term accumulation will lead to heavy pollution of tap water, and the tap water delivered to each household will not meet the direct drinking standard.
Therefore, even if it is factory-qualified tap water, you still need a water purifier for deep purification before you can drink it with confidence. At this stage, there are many types of water purifier products on the market, with different price levels and uneven quality. So how should you choose a safe water purification product for your home?

1 There must be a product sanitation license approval

The Sanitary Supervision and Administration Measures for Drinking Water stipulate that: water-related enterprises must have a sanitation license issued by the sanitation supervision department, and be appraised by the technical supervision department, and meet the national "Drinking Water Quality Standards." If you don't even have this, I suggest you don't consider buying it.

The enterprise has a sanitary license approval document indicating that the enterprise has the qualification, ability and conditions to produce water purification equipment; the water purification products are safe and reliable, and contact parts will not cause secondary pollution. Only water purifiers with sanitary approvals are qualified products.

2 It is important to choose the right filter element

According to different purification principles and processes, water purifiers can be divided into microfiltration, ultrafiltration, nanofiltration, reverse osmosis and other types. Among them, RO reverse osmosis water purifiers have the highest filtration accuracy.

The pore size of the reverse osmosis membrane is only one-thousandth of that of bacteria and viruses, and only water molecules and dissolved oxygen are allowed to pass. Other impurities in the water such as chemical pollutants, bacteria, viruses, heavy metals and other harmful substances are almost completely intercepted and eliminated. As far as drinking water is concerned, it is recommended that you choose water purification equipment with higher filtration accuracy to ensure drinking water safety.

3 Must have perfect after-sales service

After purchasing certain brands of water purifier products, many consumers cannot find the repair service call or repair service method. This situation makes consumers very helpless and wastes resources. Many water purifiers become The furnishings.

The after-sales service of the water purifier mainly focuses on the replacement of the filter element. If the filter element is not replaced for a long time, the water quality will be polluted, and the water purifier will also become a "sewage device". When choosing a water purifier product, you must choose a brand with a complete after-sales service system, such as the use of the Internet of Things service system to track equipment usage, so as to promptly remind users to replace filter elements and deal with equipment failures.
