The Trustech video page gives a practical look at how hollow-fiber and flat-sheet membranes are used in environmental water treatment, MBR systems, medical hemodialysis, and gas separation. It shows short clips of spinning with spinnerets of different sizes—8, 16, 20, and 128 holes—so you can see how production scales from lab to full industry.

The page also shares some tips for tuning membrane spinning, explains the key features and real-world uses of FCT spinnerets, and walks through the spinneret design's generational evolution. It tackles common problems too: why eccentric (off-center) fibers happen and how to fix uneven flow in multi-hole (like 20-hole) spinning. The videos include setting the right dope/core flow ratio, coagulation-bath conditions, and take-up speed—offering end-to-end guidance for industry practitioners, from equipment selection and process optimization to troubleshooting.
