Membrane Fouling and Cleaning

Membrane fouling occurs when solutes deposit on the membrane surface or inside the membrane pores. Deposits reduce product water generation and increase pressure. Research into membrane foulants includes:

Research on the removal of foulants from the membrane surface included:

fouled membrane


In an autopsy, we take an element apart to determine why it failed.
