Analysis of several reasons for the peculiar smell of ultrapure water machines

     Ultrapure water machines use a reverse osmosis membrane to selectively pass a solvent (usually water) to retain ionic species. The static pressure difference across the membrane is used as the driving force to overcome the osmotic pressure of the solvent, allowing the solvent to pass through the reverse osmosis membrane. It realizes a membrane process that penetrates the membrane and separates the liquid mixture. The membrane separation device can remove particles, colloids, organic impurities, microorganisms, other harmful substances and 99% of dissolved salts in water to achieve the purpose of desalination and water purification.

Occasionally there is an odor when using the ultra-pure water machine, which is a headache for many users. Generally, the smell of the equipment can be summarized as the following problems:

1. Bacterial organisms

If the laboratory ultra-pure water machine suddenly has an odor, it may be due to the change of the raw water quality that the influent water contains a large number of bacterial organisms, resulting in a fishy odor. In this case, you can check whether the raw water quality is abnormal, and the reverse osmosis membrane can be used. Filter out.

2. Chemicals

If the odor in the effluent of your laboratory ultrapure water machine is produced after sterilization and cleaning, it is very likely that the residual sterilization liquid and protective liquid in the filter element were not rinsed when cleaning the ultrapure water machine. Turn on the backwash function and continue to wash for 15-30 minutes to solve the problem.

3. Activated carbon fails

If the activated carbon of your ultra-pure water machine has not been replaced for a long time, there is a peculiar smell in the water of the laboratory ultra-pure water machine, which may be caused by the failure of the activated carbon consumables. You can inform the professional manufacturer after-sales team to replace the activated carbon consumables to solve it.

4. The material of the product is unqualified

Some manufacturers will use cheap and inferior materials when manufacturing ultrapure water machines, which will cause the water quality of ultrapure water machines to fail to meet the standard during the use of ultrapure water machines. Users need certification and review in the process of selecting ultrapure water machines. Brand, choose a brand that is assured and guaranteed.
