Do you know how to maintain Pleated Filter Cartridge?

Dec. 07, 2019

Maintenance of Pleated Filter Cartridge:

When the Pleated filter cartridge cannot be used to meet the designed flow rate (the pressure gauge difference between the front and back of the flow rate is significantly lower than 0.1 MPa), please open the filter after the shutdown, remove the filter element, rinse the surface with clean water, and then soak in 4% hydrochloric acid Hours, soak in 4% sodium hydroxide for 24 hours, and then rinse with water.

Cleaning and sterilization of Pleated filter cartridge:

1: Generally choose backwash on the production line: first turn off the raw liquid and filter liquid pipeline switches, rinse with bacteria-free water, input from the original outlet, and discharge from the inlet or the drain hole at the bottom of the filter. The backwash must be pressured but not over. Large, usually around 5 kg.

2: Remove the filter element and wash it in the cleaning solution. Soak it in repeated cleaning. Cleaning fluids are generally available:

 A: Sodium hydroxide, 0.1N NaOH

B: 1-2% citric acid water solvent or 0.1N oxalic acid solvent, 0.1N hydrochloric acid solvent

C: other solvents such as enzyme solvents, the general temperature control during cleaning is 30-40 degrees Celsius is best

Notes: The high-protein content of the filtered stock solution, such as draft beer and nutrient solution, must be disinfected at high temperature after the filter element is cleaned to prevent the high-temperature protein condensation from blocking the membrane pores.

Fiberglass Filter Cartridge

Fiberglass Filter Cartridge

Next, let me talk about the characteristics of Fiberglass Filter Cartridge:

Divided into domestic filter materials and imported filter materials

Can be made with different materials for the needs of different filter media;

Low pressure and large capacity to absorb suspended matter from the filtrate

Large filtering accuracy range, a wide range of use, long use time, etc.

Fiberglass filter cartridge recommendation: wire wound filter element, hydraulic oil filter element, oil filter element, etc.

Fiberglass filter cartridge principle:

Fiberglass filter cartridge is a new type of liquid and air purification filter element made by advanced technology with composite glass fiber membrane as a filter medium. The composite glass-fiber filter membrane is composed of polypropylene fiber membrane on both sides of the traditional ultra-fine glass fiber membrane. It retains the high porosity of ultra-fine glass fiber membrane, large flux, large flow rate, good temperature and corrosion resistance. And other advantages, it overcomes the shortcomings of low strength of glass fiber membrane, easy to break under pressure, and shedding. It is a new type of filter element with excellent performance and wide application.
