Microporous titanium rod filter cartridge cleaning
Microporous titanium rod filter use of different areas, cleaning methods are slightly different, as follows:
1, pharmaceutical and chemical industry: decarbonization filter, often using backflush, backwash method and combined with ultrasonic cleaning the best.
2, the system of water: the filter surface retention mostly non-water-soluble salts and oxides, generally 5% nitric acid soaking, without ultrasonic cleaning, you can achieve the cleaning effect.
3, the original liquid filter, to combine the chemical properties of pollutants, respectively, the following methods for cleaning:
(1) Alkali washing: 3-5% sodium hydroxide solution with pure solution soak 30-60 minutes, the temperature of about 40 degrees, the best in the ultrasonic cleaning machine. After soaking with deionized water or water sprayed inside and outside to neutral, measured conductivity. With pure air ≥ 0.4MPa pressure drying.
(2) pickling: 5% nitric acid solution soak for 8 hours or more, the temperature is about 40 degrees. Best in ultrasonic cleaning machines. After soaking with deionized water or water sprayed inside and outside the water to neutral, side conductivity. With pure air ≥ 0.4MPa pressure drying.
(3) organic pollution can be combined with surfactant cleaning, cell debris pollution system combined with enzyme cleaning effect is more ideal (food and beverage can be used high concentration of citric acid cleaning).
The above methods can be used alone, can also be used in conjunction with each other. If conditions, combined with ultrasonic cleaning machine the best results.
Microporous titanium rod filter filter should always online backflush, backwash, reduce the number of times with the above method of cleaning.
