Physical Cleaning Methods: Reverse-Flow by Clean Water; Reverse-Blow by Clear Air and Ultrasonic Wave
Chemical Cleaning Methods: Use Cleaning Agent Such As Diluted Acid, Diluted Alkalis, Oxidizer, and Surfactant
| Contamination Materials | General Cleaning Method Procedures |
| Decarburization in Pharmaceutical and Chemical Industries | Reverse-blow and reverse- ow used more frequently; ultrasonic wave cleaning used when necessary |
| Non -Water Soluble Salts and Oxides in the Pharmaceutical Industry | Soak in 5% Concentration of Nitric Acid Solution |
| Original Liquid Filtration | Choose the correct cleaning methods as per the chemical properties of the contamination material; The Ultrasonic Wave Cleaning can be combined to use when necessary |
| Chemical Cleaning Methods | Detailed Procedures |
| Alkaline Cleaning | Alkaline Cleaning Soak filter in 3-5% Concentration of AR grade NaOH Solution for 30-60 minutes; solution temperature is 40°C. Flush the soaked filter inside, out with DI water or WFI water until the flushed solution turns neutral , and then test its conductivity. Dry with Pure Air 0.4Mpa |
| Acid Cleaning | Soak it in the 5% Concentration of Nitric Acid Solution for at least 8 hours; solution temperature is 40°C. Flush the soaked filter inside, out with DI water or WFI water until the flushed solution turns neutral, and then test its conductivity. Dry with Pure Air 0.4Mpa |
| Original Liquid Filtration | Clean filter with surfactant caused by contamination with Organic Pollution ( high concentration of Citric Acid recommended for Food and Beverage Applications) |
