With the increase of industrial water demand, large-flow filter elements have become increasingly important. In order to maintain good filtration efficiency, it is critical to clean the filter element correctly. This paper will summarize the main matters that need for attention when cleaning the large flow filter element.

1. Plan the cleaning frequency well

According to the model and use situation of the filter element, make a reasonable cleaning frequency. It is generally recommended to clean in the following cycles:

Standard type filter element: 6 months-1 year once

High efficiency filter element: 1-2 year

Ultra-efficient graded filter element: 2-3 year once

Ensure that the cleaning interval time does not exceed 80% of the specified service life.

2. Choose the appropriate cleaning method

Select the appropriate cleaning method according to the condition of the filter element and the water treatment system.

The alternative cleaning methods include:

Reverlip cleaning, ultrasonic cleaning, high / low pressure cleaning, surfactant and acid washing and regeneration.

According to the different characteristics of the filter element, use appropriate methods to avoid damage to the filter.

3. Select the cleaning agent

Choose cleaning agents specially designed for filter element cleaning to avoid using other incompatible scale remover.

Carry out acid cleaning or alkali cleaning according to the usage condition of the filter element.

4. Pay attention to the disinfection treatment

After cleaning, high temperature heat sterilization or chemical disinfection with diluted ammonium hypochlorite solution to kill residual microorganisms.

Accordingly, ensure that the filter element meets the hygiene standards for reuse.

5. Records and storage

After cleaning, relevant information (duration, cleaning method, dose, etc.) should be recorded, and appropriate storage methods should also be screened to maintain the rigidity and function of the filter element.

6. Pay attention to safety protection

Wear protective equipment to prevent skin or eye burns caused by cleaning agents.

Avoid direct contact with the cleaning agent for a long time, and conduct air ventilation regularly.
