Analysis of reverse osmosis water purifier cleaning and maintenance, to protect the pure water quality

Reverse osmosis water purifiers are widely used in homes and offices to provide people with purer and safer drinking water. However, proper cleaning methods and maintenance techniques are essential to ensure its long-term stability. Below is a full analysis of reverse osmosis water purifier cleaning methods and maintenance techniques.

Understanding the working principle of reverse osmosis water purifier
Reverse osmosis water purifier mainly through the role of semi-permeable membrane, driven by pressure, so that the water from the high concentration side to the low concentration side of the infiltration, so that the water impurities, heavy metals, bacteria and other harmful substances intercepted, to achieve the purpose of purifying water. It is like a sieve that only allows water molecules to pass through and keeps all other impurities out. The semi-permeable membrane is the core component in this process, but it is also susceptible to contamination, which affects the performance of the water purifier.

The importance of regular cleaning
With increased use, the membrane surface of a reverse osmosis water purifier will gradually accumulate dirt and contaminants, just like our clothes get dirty after a long time. This not only leads to a decrease in water flux, slowing down the water discharge rate, but may also increase the salt transmission rate, affecting water quality. Regular cleaning can effectively remove this dirt and contaminants, restoring the performance of the water purifier and extending its service life.

Cleaning Methods Revealed

Chemical cleaning: chemical cleaning is like doing a “deep care” to the water purifier. Usually use specific cleaning agents, such as citric acid, sodium tripolyphosphate solution. When the water purifier is found to significantly reduce the amount of water or water quality deterioration, citric acid solution can be used for cyclic cleaning to remove calcium carbonate scale and other dirt; for organic matter and living linea organisms caused by membrane contamination, you can use 0.2% sodium hypochlorite + 0.1% sodium hydroxide solution for cleaning. But in the use of chemical cleaning agents, be sure to follow the requirements of the manual to avoid damage to the water purifier.
Physical cleaning: physical cleaning is relatively simple and rough, mainly including flushing and backwashing. Flushing can be understood as a water purifier for the “shower”, through the impact of the water to remove some loose impurities; backwash is to change the direction of the water flow, the impurities on the surface of the membrane reverse flushing, like we combed backwards hair, can effectively remove some of the dirt attached to the surface of the membrane.

Maintenance Points
Regular replacement of the cartridge: the cartridge is an important part of the reverse osmosis water purifier, like our masks, need to be replaced after a period of time. Generally speaking, the PP cotton filter element is replaced every 3-6 months, the living linea carbon filter element is replaced every 6-12 months, and the RO reverse osmosis membrane filter element is replaced every 2-3 years. The specific replacement time also needs to be decided according to the local water quality and frequency of use.
Check the operating condition of the equipment: check the operating condition of the water purifier on a regular basis, including the inlet pressure, outlet flow, water quality and so on. You can understand the working condition of the water purifier by observing the display of the water purifier or using a water quality testing tool. If abnormalities are found, timely measures should be taken to deal with them.
Keep the device clean: keep the appearance of the water purifier clean to avoid dust and stains from entering the interior of the device. It is also important to keep the environment around the water purifier dry and ventilated to avoid a humid environment that could cause the device to rust or harbor bacteria.

Frequently Asked Questions and Answers
- How often should I clean my reverse osmosis water purifier?
In general, when the standardized flux decreased by 10%-15%, or the system desalination rate decreased by 10%-15%, or the operating pressure and differential pressure between sections increased by 10%-15%, the RO system should be cleaned. But the specific cleaning frequency should be based on the water quality and use.

- Can I clean my reverse osmosis water purifier with regular cleaners?
No. Ordinary cleaners may damage the membrane element and other parts of the water purifier, and a specialized cleaning agent should be used.

- What do I need to pay attention to when cleaning?
Before cleaning, cut off the power and water supply, operate according to the instructions of the cleaning agent, and rinse thoroughly after cleaning to avoid the residual cleaning solution affecting the water quality.

- Can the filter element of reverse osmosis water purifier be cleaned and reused?
Generally speaking, PP cotton cartridge and activated carbon cartridge can not be cleaned and reused, RO reverse osmosis membrane cartridge can be professionally cleaned and maintained in some cases, but there are certain service life limitations.

- How to determine whether the membrane of reverse osmosis water purifier needs to be replaced?
When the desalination rate of the membrane decreases significantly, the amount of water produced decreases significantly, and the membrane element shows obvious signs of damage or aging, it is necessary to consider replacing the membrane element.

- Reverse osmosis water purifier in the winter need to pay special attention to what?
Winter temperatures are low, care should be taken to prevent the water purifier from freezing, so as not to damage the equipment. If it is not used for a long period of time, the water in the water purifier should be drained and stored properly.

- What should I do if the water from my water purifier has an odor?
The activated carbon filter may be saturated with adsorption or bacteria, so you need to replace the activated carbon filter or clean and disinfect the water purifier.

- What is the effect of too high or too low inlet pressure on the water purifier?
High inlet pressure may damage the components of the water purifier, while low inlet pressure may reduce the water output or prevent it from working properly.

- Why is the water output of the water purifier getting smaller and smaller?
It may be due to clogged cartridge, membrane contamination, insufficient inlet pressure, etc., which need to be checked one by one and dealt with accordingly.

- How to extend the service life of reverse osmosis water purifier?
How to extend the service life of reverse osmosis water purifier? How to extend the service life of reverse osmosis water purifier? Regular cleaning and maintenance, the correct use of the water purifier, to avoid the use of poor water quality, timely replacement of the cartridge and so on can extend its service life.

Correct cleaning methods and maintenance techniques can make the reverse osmosis water purifier better serve us, providing purer and safer drinking water. I hope that the above content is helpful to you, so that you can use reverse osmosis water purifier more comfortable.
