Folded filter how clean is better?

In the folding filter selection during the process of chemical cleaning chemicals, there are certain principles. One is that it can't with filter elements and components of other materials in any chemical reaction. The second is selected drugs can prevent the secondary pollution. The following are some of our Suggestions: 1. Oxidant detergent: 1% ~ 3% H2O2, 500 ~ 1000 mg/L NaClO aqueous cleaning ultrafiltration filter, can remove dust and sterilization. H2O2 and NaClO is a common fungicides. 2. Acid solution to clean: commonly used solution including hydrochloric acid, citric acid, oxalic acid, etc. , make the pH of the solution for 2 ~ 3. Using a loop clean or soak 0. 5 h ~ 1 h, then circulation cleaning, better to remove inorganic impurities. 3. Alkali cleaning: common alkali including sodium hydroxide, potassium hydroxide and sodium carbonate. Preparation of alkaline solution pH value is determined by the type of filter element, usually about pH = 10 ~ 12. Use water to clean or soak 0. 5 h ~ 1 h, then wash, can effectively remove impurities and grease. 4. Enzyme detergent: 0. 5% ~ 1. 5% of pepsin, trypsin, etc. , used to remove protein, polysaccharide and grease and other pollutants.
