| Abstract |
| Membrane filtration process in water treatment can be an efficient and economical way to separate contaminants, which suspended in water. Membrane fouling is a phenomenon to decrease water flux and increase operating pressure. It is important to normalize a membrane process by cleaning a fouling membrane as well as to predict membrane fouling. However, method of determining the cleaning characteristics of fouling membrane is insufficient. By introducing a new concept of membrane cleaning index (MCI), membrane cleaning mechanism was established by MCI through in this study. Cleaning efficiency of fouling membrane was compared and analyzed quantitatively. Cleaning index value of organic, inorganic and microbes can be indicated by membrane cleaning index. Chemical cleaning efficiency increased applying the result of membrane cleaning index to chemical cleaning. Membrane cleaning index is a useful method to indicate index of membrane cleaning properties and efficiency. |
