How does MBR membrane manufacturer conduct membrane component gas inspection?
MBR membrane manufacturers usually conduct gas inspections on membrane components during production to ensure product quality and performance. The following are the commonly used gas inspection methods for membrane components by MBR membrane manufacturers:
1. Air tightness testing:
Testing purpose: To detect whether there is any air leakage or poor airtightness in the membrane components.
Detection method: Use a pressure testing instrument to conduct an airtightness test on the membrane components and observe the changes in pressure.
2. Leakage detection:
Testing purpose: To detect any leakage in the membrane components and ensure good sealing performance.
Test method: apply foam agent or other testing agent on the surface of membrane module, and observe whether there are bubbles to determine the leakage position.
3. Gas transmittance detection:
Detection purpose: To measure the gas permeability of membrane components and evaluate the filtration performance of the membrane.
Detection method: Use gas permeability testing equipment to pass different gases into both sides of the membrane component, and measure the permeability to evaluate the filtration effect of the membrane.
4. Gas diffusion detection:
Testing purpose: To test the ability of membrane components to diffuse gases and evaluate the mass transfer performance of the membrane.
Detection method: Using gas diffusion testing equipment, measure the diffusion rate of membrane components towards different gases and evaluate the mass transfer performance of the membrane.
5. Gas permeability testing:
Detection purpose: To measure the permeability of membrane components to gas and evaluate the separation effect of the membrane.
Detection method: Using a gas permeability testing instrument, measure the permeability of membrane components to different gases and evaluate the separation effect of the membrane.
MBR membrane manufacturers can ensure that product quality and performance meet standard requirements by conducting strict gas inspections on membrane components. Regularly conducting gas inspections, promptly identifying and addressing issues, can help improve the service life of membrane components and wastewater treatment efficiency.
