Contamination MaterialsGeneral Cleaning Method Procedures
Decarburization in Pharmaceutical and Chemical IndustriesReverse-blow and reverse-ow used more frequently; ultrasonic wave cleaning used when necessary
Non -Water Soluble Salts and Oxides in the Pharmaceutical IndustrySoak in 5% Concentration of Nitric Acid Solution
Original Liquid FiltrationChoose 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 MethodsDetailed Procedures
Alkaline CleaningAlkaline 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 CleaningSoak 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 FiltrationClean filter with surfactant caused by contamination with Organic Pollution ( high concentration of Citric Acid recommended for Food and Beverage Applications)
