There is a close relationship between filtration accuracy and flow, mainly reflected in the following aspects:
1. Filtration accuracy
Refers to the smallest particle size that the filter can capture and remove, usually expressed in micrometers (μm). High-precision filters remove smaller particles and provide a clearer fluid.
2. Traffic
Refers to the amount of fluid passing through the filter in a unit time, usually expressed in units such as liters per minute (L/min) or cubic meters per hour (m³/h). Flow rate reflects the capacity of the filter to carry water.
3. Mutual influence
In general, the higher the filtration accuracy, the smaller the porosity inside the filter and the greater the resistance to the fluid, which will cause the flow rate to decrease. On the contrary, lower filtration accuracy usually means larger porosity and higher flow rate.
4. Consider options of the filter
When selecting filters, it is necessary to balance the relationship between filtering accuracy and flow rate according to the application requirements. For example, for fluid handling that requires high purity, some flow may need to be sacrificed to ensure adequate filtration accuracy.
5. System design of the filter
In system design, the overall flow rate can be increased by using multiple filters in parallel or by selecting a larger filter size while maintaining the desired filtration accuracy.
6. Maintenance and monitoring
The flow rate of the filter may decrease with increasing use time, which may be due to blockage or contamination of the filter element. Therefore, regular inspection and maintenance of the filter is an important measure to ensure flow and filtration accuracy.
7. Technological progress of the filter
With the development of technology, the emergence of new filter materials and designs, such as filter elements using nanofibers or multilayer structures, is improving the filter's ability to achieve high flow rates while maintaining high filtration accuracy.
