Membrane filtration process in water treatment can be an efficient and economical way toseparate contaminants, which suspended in water. Membrane fouling is a phenomenon to decreasewater flux and increase operating pressure. It is important to normalize a membrane process bycleaning a fouling membrane as well as to predict membrane fouling. However, method ofdetermining the cleaning characteristics of fouling membrane is insufficient. By introducing a newconcept of membrane cleaning index (MCI), membrane cleaning mechanism was established by MCIthrough in this study. Cleaning efficiency of fouling membrane was compared and analyzedquantitatively. Cleaning index value of organic, inorganic and microbes can be indicated by membranecleaning index. Chemical cleaning efficiency increased applying the result of membrane cleaning indexto chemical cleaning. Membrane cleaning index is a useful method to indicate index of membranecleaning properties and efficiency. |
