Pure water system use precautions

Pure water system water source:

Pure water systems (reverse osmosis and distilled water systems) use ordinary urban tap water as a water supply. Due to the secondary pollution of tap water in the water supply process or the serious pollution of the tap water source, the water quality of the user pipeline may be extremely reduced. In order to effectively prevent such pollution from irreversibly destroying the key components of the pure water system, it is necessary to Select the appropriate pre-filtration protection device for the water quality of the pipeline water supply. The main purification functions of the unit should include:

Reduce sludge index, reduce residual chlorine content, and reduce water hardness (making LSI negative)

This device can also effectively reduce the user's pure water system use cost. The user needs to replace the filter elements of the pre-filter protection device in time to ensure the effectiveness of the device.

Pure water system power supply:

The pure water system should be installed in a location where the power supply is stable. If the power supply is unstable, it may adversely affect the system function. In severe cases, the system board may be burnt.

Pure water system site:

Ultrapure water systems should be installed in as clean a laboratory as possible to ensure that their ultrapure water is not contaminated. The installation site of the pure water system needs to be properly close to the upper and lower water pipes, and the installation points should be kept ventilated and dry to avoid direct sunlight.

Pure water system maintenance:

※ The user should periodically replace the purification column according to the instructions of the manufacturer's engineer and the pure water system itself, and pay attention to the alarm prompts of the system. Contact the service engineer according to the requirements of the user manual.
※ When using the pure water system for daily use, it should be used as much as possible to maintain the normal supply of power and water. However, for special reasons, when the pure water system has to be stopped for a long time, you can refer to the following methods:

* * Countermeasures for long-term deactivation of ultrapure water manufacturing systems

If the pure water or ultrapure water system is deactivated for a long time due to laboratory renovation or long rest, in order to make the experiment work properly in the future, certain measures must be taken.

If the period of inactivity is from 1 week to 10 days, and the power and water sources are not affected, the system can remain in operation and continue to obtain stable purified water. If the water pipe works, the system must be completely stopped. At this time, the water supply switch and power supply of the pure water system should be turned off, and the connection with the supply water should be disassembled. The pure water in the water tank will be completely drained due to deterioration of water quality due to standing for a long time.

After the end of the decommissioning period, if you use the system again, you should pay attention to it. Especially after the water pipe repair, there will be a lot of pollutants in the supply water. Therefore, the water supply faucet should be fully drained to stabilize the water quality. Turn on the water switch connected to the system to start the system. This procedure prevents large amounts of pollutants from flowing into the system.

If the system still does not function properly after taking the aforementioned countermeasures, it may be caused by blockage of various purification columns and filters during the deactivation. Therefore, the problematic part should be replaced.

Water in pure water system:

When taking water from a pure water system, care should be taken to avoid secondary pollution. In particular, the ultra-pure water system is very easy to be polluted. Therefore, when using ultrapure water, it should be used immediately and avoid storage.

Pure water system cost:

Timely replacement of low-cost pretreatment columns is an effective way to reduce the cost of use. For ultrapure water systems, the resistivity readings can be made correct by periodic calibration system built-in resistivity monitors, based on the data of the resistivity monitor and the time of use of the ultra-purified column (generally no more than 2 years) ) to decide whether to replace the ultra-purification column.
