Cleaning Methods

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)
