How Often to Change the Filter Cloth?

The quality of the filter cloth is closely related to the filtration effect of the filter press. Damage to the filter cloth will greatly reduce the filtration efficiency of the filter press. The average lifetime of the filter cloth is about 3-6 months. There is no fixed time, and it mainly depends on the materials being filtered and the frequency of use of filter cloth, etc.

Factors Affecting Filter Cloth Performance

1. Filtered materials

The filtered materials will greatly affect the performance of the filter cloth. For example, filtering some materials containing larger particles or highly corrosive chemical materials will greatly reduce the service life of the filter cloth.

2. Frequency of use of filter cloth

For occasions with large processing capacity, the number of filtrations is greater and the filter cloth is used more frequently, so the filter cloth has a shorter life and needs to be replaced frequently.

3. Cleaning and maintenance of filter cloth

Regular inspection and maintenance of filter cloth is crucial. After each filtration, the remaining filter cake should be cleaned in time to keep the filter cloth clean. At the same time, regular maintenance is required to increase the service life of the filter cloth.

Signs that the filter cloth needs to be replaced

1. Filtering time is getting longer and longer

When the performance of the filter cloth declines, each filtration time will be longer than before. If you find that the filtration time is getting longer and longer, it means that the filter cloth needs to be replaced.

2. The filter cake becomes wet

If you find that the filter cake becomes wet and slippery after filtration and is not as dry as before, then there is a problem with the filter cloth, and it needs to be replaced in time.

3. The filtrate becomes turbid

Pay attention to the filtrate flowing out of the filter. Once you find that the filtrate has become turbid and no longer transparent, it means that a new filter cloth needs to be replaced.

4. The filter cloth is obviously damaged

As the use time increases, the filter cloth will wear out due to the friction of the machine. If any holes are found in the filter cloth, it needs to be replaced in time.

In short, the service life of filter cloth is affected by many factors, and there is no fixed period. Selecting the appropriate filter cloth according to the specific application and performing regular maintenance according to the maintenance guide is the best way to increase the service life of the filter cloth.
