How to effectively avoid the growth of microorganisms in the high-purity water machine?

       During the daily operation of the high-purity water machine, some impurities will sometimes remain inside the equipment, which will lead to the growth of microorganisms for a long time, and this situation will affect the operation of the equipment, so what should be paid attention to to prevent the growth of microorganisms in the high-purity water machine? Let's take a closer look below.

1. Frequently change the operating environment of the equipment, so that the microbial substances are not suitable for the growth environment. The current method is mainly to affect the growth of fungi by changing the pH value of the influent water, reduce the reproduction rate, or even die;

2. Regularly dosing non-oxidizing fungicides, a large number of operating experience has proved that regular dosing of non-oxidizing fungicides is an effective means to control the breeding of microorganisms by reverse osmosis during operation. In view of the current situation, it is recommended to do the dosing every week first, and gradually extend the dosing cycle after the system is stabilized;

3. Regular chemical cleaning, it is recommended to purchase reverse osmosis cleaning agent for regular reverse osmosis cleaning. After the reverse osmosis membrane runs for a period of time, the substances retained on the surface of the reverse osmosis membrane are difficult to remove by physical methods. Chemical cleaning can effectively remove the inorganic salts and organic microorganisms accumulated on the surface of the membrane, prolong the service life of the membrane, and reduce the total production cost. ;

4. Regularly replace the filter element of the equipment. According to the filter manual, it should be replaced when the pressure difference increases to 0.2MPa, but in actual production, it is found that when the pressure difference rises above 0.05, there are already a lot of impurities trapped (the relevant staff finds the foreign matter inside the security filter when the pressure The difference is only 0.03MPa), the foreign matter that is still put into operation at this time is likely to enter the reverse osmosis with the incoming water and affect the operation of the reverse osmosis. Therefore, the inspection of the security filter should be regarded as the work content of regular inspection. Replace the filter in time.

The above is the method to prevent the growth of microorganisms in high-purity water machines. Only by effectively preventing the growth of microorganisms can the water quality meet the requirements.
