Single-saltwater Gore membrane
Thread Content
I have a question: In a brine Gore membrane process, there are many bubbles of brine in the Gore membrane. I have checked all other possible causes, including the liquid level in the feed tank – what other reasons could there be? I would appreciate any experience you can share. Thank you
Each membrane group consists of dozens of membranes, which are secured by one gland. This is caused by the gland not being secured tightly enough, or by the reduced elasticity of the membrane head after it has been in use for a long time. Be careful if there are many bubbles; these bubbles remain as a result of incomplete exhaust at the top of the membrane. If the filtration process lasts for too long and all the bubbles are expelled, the water output will not meet the standards. Solution: 1. Adjust the filtering time to ensure that bubbles are present throughout the filtering cycle ； 2. Re-fix the gland; if the diaphragm head has lost its elasticity, add more soft PTFE and tighten it again.
It is caused by excessive pressure of the saline entering the membrane.
30KA shouldn’t be considered high, right?
If it are small bubbles and only present in certain areas, there’s no need to worry about them; if they are large bubbles that are rolling around, check whether the flexible valve used for activation is damaged. The liquid level in the feed tank should be maintained at 40-60%.
