Dawning-talk about the filter: can increasing the water inlet diameter increase the flow rate of the filter?

Dawning has been focusing on the application of the first filtration system for agricultural irrigation for many years. I often encounter the problem that some users increase the water inlet diameter of the gravel filter in pursuit of large flow.

So, can increasing the inlet diameter really increase the filtration flow?

       The answer is no

       why?

       Because the flow rate of the sand filter is related to the tank size of the filter, when the tank size and filter layer height remain the same, the flow rate of the quartz sand does not change, that is, the processing capacity does not change; therefore, increase the sand filter The water inlet diameter of the filter cannot increase the flow rate of the filter.

On the contrary, if the water inlet diameter of the sand filter is increased, too much water enters the filter, which may also cause the following two problems:

        1. The pressure at the water inlet increases, the pressure difference between the inlet and outlet rises rapidly, and the equipment will continuously backwash;

        2. Too much water will greatly increase the flow rate through the medium, and too high a filtration rate will greatly reduce the adsorption and interception capacity of the filter material, and the filtering effect will also be greatly reduced.
