Maintaining the ultrapure water machine is the key to its long-term normal operation and production of high-quality ultrapure water. The following are the daily maintenance points of the ultrapure water machine:

1. Regularly replace filter cartridges and consumables

The filter element and consumables in ultrapure water machines are key components that directly affect water quality and equipment performance. Regular replacement can extend equipment life and maintain stable water quality.

Pre treated filter cartridge: usually includes PP cotton, activated carbon filter cartridge, etc. These filters are responsible for filtering particulate matter, residual chlorine, and organic matter. It is recommended to replace them every 3-6 months, and the specific replacement frequency depends on the water quality and usage.

RO reverse osmosis membrane: The RO membrane is the core component for removing most impurities from water. It is recommended to replace it every 1-2 years, especially when the water flow rate is significantly reduced or the conductivity is increased. It is necessary to check and replace the RO membrane in a timely manner.

Ultra purification column: responsible for removing trace impurities and ions from water, regularly checking whether the conductivity of the effluent meets the standard, and replacing the ultra purification column if the water quality decreases, usually every 6 months to 1 year.

2. Keep the water tank and pipes clean

Long term use of the water tank and pipeline of the ultrapure water machine can accumulate fine Jun and impurities, which can easily cause secondary pollution and affect water quality.

Regularly clean the water tank: It is recommended to clean and disinfect the water tank every 1-2 months to prevent the growth of fine particles and the accumulation of sediment.

Pipeline disinfection: Regular disinfection and flushing of pipelines can be carried out, especially when the ultrapure water machine has not been used for a long time. Flushing the pipeline can eliminate residual water and impurities, ensuring pure water quality for the next use.

3. Maintenance of reverse osmosis membrane

Reverse osmosis membrane is one of the core components, which directly affects water quality and equipment performance.

Regular flushing: Reverse osmosis membranes are prone to clogging or contamination due to impurities in the water. It is recommended to backwash the membrane every 2-3 months to remove surface deposits and maintain its high permeability.

Preventing membrane fouling: If the water quality is hard (such as high calcium and magnesium ion content), it is recommended to install a water softener or add anti fouling agents to prevent membrane surface fouling.

4. Control the quality of incoming water

Inlet water quality testing: The inlet water quality has a significant impact on the ultrapure water machine. It is recommended to regularly test the parameters such as conductivity and hardness of the inlet water to ensure that it meets the equipment requirements.

Use softened water: If the tap water quality is hard, it is recommended to install a water softener before the ultrapure water machine to reduce the calcium and magnesium ion content and prevent RO membrane scaling.

5. Regularly check water quality

Monitoring effluent water quality: Ultra pure water machines are generally equipped with conductivity or resistivity monitoring equipment. It is recommended to regularly check water quality indicators to ensure that the water quality meets the standards of ultra pure water. If there is a fluctuation in water quality, the status of the equipment filter element, RO membrane, and ultra purification column should be checked immediately.

Installation of online monitoring instruments: Online conductivity or resistivity monitoring instruments can be installed to monitor water quality changes in real time and detect problems in a timely manner.

6. Maintenance during shutdown

Maintenance when not in use for a long time: If the equipment is not in use for a long time, it is recommended to drain the water inside the equipment, turn off the power, and avoid the accumulation of water inside the equipment to breed fine dirt or scale. When reusing, rinse first and then make water normally.

Shutdown flushing: Before not using the equipment for a long time, the water in the water tank and pipeline can be drained through a flushing program to prevent the accumulation of water and the growth of fine Jun particles.

7. Regularly clean the external and surrounding environment

External cleaning of equipment: Regularly clean the casing and display screen of the ultrapure water machine to avoid the accumulation of dust and dirt.

Ensure a clean environment: Keep the room where the ultrapure water machine is located clean and ventilated to avoid the equipment being affected by dust or other pollutants. The equipment should be placed in a dry, ventilated, and non corrosive gas environment.

8. Regular maintenance and professional upkeep

Check electrical components: Regularly inspect the electrical components of the ultrapure water machine, including the water pump, solenoid valve, and other parts, to ensure that they are working properly. If any abnormalities are found, they need to be repaired or replaced in a timely manner.

Regular professional maintenance: It is recommended to invite professionals to conduct a comprehensive inspection and maintenance of the ultrapure water machine every year, including circuit, mechanical components, pressure testing, etc., to ensure that the equipment is in good working condition.

9. Prevent the growth of bacteria and microorganisms

Regular Jun killing treatment: If the ultra pure water machine is used in a high humidity environment or with low equipment usage frequency, it is recommended to perform Jun killing treatment regularly to prevent microbial growth and affect water quality. You can use the recommended disinfectant from the equipment manufacturer for cleaning.

Timely use of ultrapure water: The purity of ultrapure water is extremely high, and it is easy to adsorb substances such as carbon dioxide and fine Jun in the air. It is recommended to use the produced ultrapure water as soon as possible to avoid prolonged exposure to the air.

10. Reasonable use

Avoid overuse: Ultra pure water machine equipment should not work continuously for long periods of time. It is recommended to control the water production rate within the rated range of the equipment each time to avoid overheating or overload due to long-term operation.

Choose appropriate water quality requirements: Different experiments or applications have different water quality requirements. Reasonably select different water quality types such as pure water and ultrapure water to reduce unnecessary losses.

Through daily maintenance and regular upkeep, the service life of the ultrapure water machine can be extended, ensuring the normal operation of the equipment and continuously providing high-quality ultrapure water.
