| 摘要 |
The present invention relates to a chemical cleaning method for an RO/NF membrane system consisting of two arrays and, more particularly, to a chemical cleaning method for an RO/NF membrane system consisting of two arrays, capable of predicting a substance that causes membrane fouling and chemically cleaning a reverse osmosis membrane module and a nanofiltration membrane module using a chemical cleaning agent suitable for the substance, thereby restoring and maintaining the filtration performance of the membrane. The membrane fouling phenomenon occurs due to various causes during the membrane filtering process. In this case, the present invention can enhance cleaning efficiency by predicting a substance that causes membrane fouling and performing chemical cleansing with a chemical cleaning agent suitable for the substance. Accordingly, a longer chemical cleaning cycle is guaranteed, thereby reducing the time consumed for chemical cleaning, chemical costs, etc. |
