The 'pure water machine' is a popular name for RO reverse osmosis water purifiers. There are also RO reverse osmosis water purifiers. People who install water purifiers in their homes usually encounter a situation where the water volume becomes smaller. Reverse osmosis water purifiers have slow water production. Most people habitually attributed it to RO membrane blocking. They want to change membranes and then start buying new filter cartridges for replacement. However, as reverse osmosis membranes, Just want to say: After all, there are many reasons why the pure water mechanism causes water to slow down. You are sure that it is me. Don't you realize that sometimes you change the filter, the flow rate is still very small. What is the reason?
One, film clogging
Let's first look at the factors that affect membrane blockage. Knowing these primary factors, we can avoid the recurrence of similar phenomena in the later period.
1, The membrane has been used for a long time, some have been used for two years, three years, or longer. According to the specification, the life span of the membrane is one and a half to two years. The raw water quality factors, water consumption and raw water quality are generally proportional to the life of the membrane, so it is necessary to replace the filter cartridge according to your own water quality and frequency of use.
2. The front filter core does not change for a long time, which causes the water concentration in the machine to stagnate. It is far worse than the water quality before entering the machine.
3, the raw water quality is poor, the concentrated water ratio is rather small, causing the thick water solenoid valve or flushing combination valve to clog, and the machine is not drained, or there is very little condensed water, then the short life of the membrane is expected. Now.
4. The quality of the film itself is poor. Like how low or how low the price is, the film of the bad street, where do you expect it to go? This is very important. The original intention of our purchase of the water purifier is for the family to drink. In healthy water, if the membrane itself has problems, it will not only give us no health water, but it will hurt our body. Therefore, please remember that you must purchase a regular water filter of a regular manufacturer's brand!
Second, the filter plug
As a metaphor, the filter element of the water purifier is like the kidney of our body. The quality of the effluent of the water purifier depends not only on the quality of the filter element, but also on whether the service life of the filter element is replaced in time. If the filter element takes too long, When it is replaced, it will cause water clogging, the water flow will become smaller and smaller, and it will cause the entire clean water system to be polluted for a long time.
Therefore, the user must develop a good habit of regularly replacing the filter element. The general specification of the water purifier manufacturer will not be subject to arbitrary charging. The core replacement cost is not high, and now the regular brand water purifier basically has a filter replacement prompt. It is also a good guarantee that we will not forget to change because of busy work.
Third, the rear active cotton plug
This situation generally occurs after the replacement of new post-activated carbon. Because there is too much toner, there is no flushing. Therefore, generally, the granular activated carbon filter cannot be filled too much (not for cutting corners), and the space for filling must be reserved. Water flow, on the one hand, the activated carbon itself also has an expansion coefficient, which is still the old saying. Regular water purifier manufacturers will take this into consideration. Therefore, there is no need to say more.
Fourth, the temperature is low
RO membrane water production rate and temperature have a great relationship, not more than 40 degrees, not less than 5 degrees. The general temperature is 25 degrees. In 25 degrees, generally every one degree lower, the water production will be reduced by 3%.
Therefore, the winter water production rate is generally reduced by more than half or even more than in summer. Users in rural areas need to pay special attention to cold and frost protection. In winter, the filter bottles, membrane shells, and concentrated water pipeline outlets are not allowed to be stored outdoors.
Also, the weather is getting hotter now. If your water purifier is installed on a kitchen or on a balcony where there is light, remember to find a shelter that will block it, otherwise it will not only reduce the amount of water produced, but also increase the temperature. The temperature inside the machine is high, it is easy to breed bacteria.
Fifth, pump booster
The pump booster pressure is small and usually occurs in reverse osmosis water purifiers with a service life of more than two years, or water purifiers that are in long-term working condition. The principle of water production in pure water purifiers is driven by pump pressurization until the water can pass through reverse osmosis. The pressure needed for membranes is generally about 6-7 kg for domestic water purifiers, and about 4-6 kg for reverse osmosis commercial machines. Increased user water consumption and water quality pollution may lead to shortened pump life.
