What should we pay attention to when using reverse osmosis water purification equipment?

Although reverse osmosis water purification equipment has many advantages, you also need to pay attention to the following points:

Source water quality: The quality of source water directly affects the life and performance of the reverse osmosis membrane, so it is necessary to regularly detect the water quality parameters of the source water, such as turbidity, color, hardness, PH value, residual chlorine, iron and manganese, organic matter, microorganisms, etc. , select appropriate pretreatment equipment and processes according to the actual situation to ensure that the water inlet quality of the reverse osmosis membrane meets the requirements.

Reverse osmosis membrane cleaning: During long-term operation, the reverse osmosis membrane will be contaminated by impurities and harmful substances in the water, causing the performance of the reverse osmosis membrane to decline. Therefore, the reverse osmosis membrane needs to be cleaned and disinfected regularly to restore the performance of the reverse osmosis membrane. Performance and longevity. The method and frequency of cleaning and disinfection should be determined according to the actual situation, usually once every 3-6 months.

Replacement of reverse osmosis membrane: During normal use, the reverse osmosis membrane will age and wear out over time, resulting in a decline in the performance of the reverse osmosis membrane. Therefore, the reverse osmosis membrane needs to be replaced regularly to ensure the reliability of the reverse osmosis water purification equipment. normal operation. The replacement cycle should be determined according to the actual situation, usually once every 2-3 years.

Use of reverse osmosis water purifier: The reverse osmosis water purifier is a small household or commercial reverse osmosis water purification equipment. It can directly turn tap water or bottled water into pure water for people to drink or cook. When using a reverse osmosis water purifier, you need to pay attention to the following points:

Installation location: The reverse osmosis water purifier should be installed in a ventilated, dry, and cool place to avoid direct sunlight and high temperature environments to prevent bacterial growth and membrane element aging.

Inlet and outlet water pressure: The reverse osmosis water purifier needs a certain inlet and outlet water pressure to work properly, generally 0.1-0.4 MPa. If the inlet and outlet water pressure is too low or too high, it will affect the water production and purification effect of the reverse osmosis water purifier, and even damage the equipment. Therefore, before installation, check whether the pressure of tap water or bottled water meets the requirements. If it does not meet the requirements, you can install a booster pump or pressure reducing valve to adjust the pressure.

Proportion of wastewater produced: During the working process of the reverse osmosis water purifier, two water flows will be produced: one is pure water (also called produced water), and the other is concentrated water (also called wastewater). The ratio of produced water to wastewater refers to the flow ratio of produced water to wastewater, which is generally 1:3 or 1:4. The higher the proportion of wastewater produced, the higher the purification efficiency; the lower the proportion of wastewater produced, the lower the purification efficiency. Therefore, when using a reverse osmosis water purifier, the proportion of wastewater produced should be adjusted according to the actual situation to achieve the best state. The adjustment method is to control the flow of wastewater by rotating the wastewater valve. The more the wastewater valve is opened, the greater the wastewater flow and the lower the proportion of wastewater produced; the more closed the wastewater valve is, the smaller the wastewater flow is and the higher the proportion of wastewater produced.

Pure water storage: Reverse osmosis water purifiers are generally equipped with a pure water storage barrel to store the produced pure water for people to use at any time. Pure water storage barrels should be kept clean and hygienic, and should be cleaned and disinfected regularly to prevent bacterial growth and secondary pollution. The capacity of the pure water storage barrel should be selected according to the use needs and water production speed, generally 3-12 liters. Pure water storage barrels should be placed in a ventilated, dry, and cool place to avoid direct sunlight and high temperature environments to prevent algae growth and membrane element aging.


Reverse osmosis water purification equipment is a highly efficient purified water equipment that can remove most impurities and harmful substances in source water. The pure water produced can be used for various purposes such as drinking, cooking, washing, and industry. The working principle of reverse osmosis water purification equipment is to use semi-permeable membrane technology to separate water and solutes. Its core component is the reverse osmosis membrane. Reverse osmosis water purification equipment has the advantages of energy saving, environmental protection, compact structure, and simple operation. However, it is also necessary to pay attention to issues such as source water quality, reverse osmosis membrane cleaning, and replacement of reverse osmosis membranes to ensure the normal operation and performance of reverse osmosis water purification equipment.
