7 Common Causes of Membrane Fouling & Degradation

July 31, 2020 · By Nathan Olszak
What Are Common Causes of Membrane Fouling & Degradation? Feed Water Considerations Fouling is a process during which continuous buildup of contributing deposits reduce the function and efficiency of the operating system. Membrane systems are mechanical and therefore subject to fouling on the surface. This fouling ultimately degrades the membranes. There are 3 main causes [...]
