What is the role of large flow filter membrane?
the big flow filter and filter membrane soaking in solution, through the control system in a side pressure treatment, the adjusting air intake;
with the increase of the pressure of gas will be released from the side of the membrane, the membrane surface will form different sizes of bubbles and instrument to corresponding pressure of bubble point value judgment.
when the gas pressure in the flow of water filter bubble point values of 80%, a large amount of gas hole filter don't happen, but have a small amount of gas dissolved, then from the liquid to spread to the other side, is called diffusion current.
due to the bubble point values for a qualitative value, but the bubble volume could not be determined accurately, and the diffusion flow value is a quantitative value, to be able to accurately determine the integrity of the filter, can also reflect the membrane, flow rate and the gap area, thus more effective.
