Explanation on ultrafiltration dispersion chemical cleaning
Thread Content
Dear teachers, I have been working with ultrafiltration and reverse osmosis processes recently. The CEB method for ultrafiltration refers to dispersed chemical cleaning: a chemical agent with a certain concentration and specific properties is added to the product water side of the membrane, and the contaminants on the membrane surface are removed through flow immersion. This cleaning method is also known as dispersed chemical cleaning. Could someone explain what exactly the phrase \"dispersed by 2\" means? ? Why is such chemical cleaning called dispersion chemical cleaning?
There are several types of dispersants. The first type is used as dispersants; during the operation of RO or UF systems, scaling in the form of calcium carbonate and magnesium carbonate forms, and chemical agents capable of dispersing such scaling substances are needed for cleaning, such as phosphorus-containing dispersants. Occasionally, scaling in the form of silicates occurs, in which case alkali-based dispersants are required； 2. Bacteria: Addition of chemical agents such as bactericides, as well as dispersants that affect the internal structure of bacteria ；
