Membrane cleaning and disinfection
Cleaning of filtration membranes

When clogging occurs in the form of a deposit, various physical unclogging techniques are available, all of which involve back filtration for a short time (backpulse, backflush, etc.) [28]: reversing the flow is comparable to a "water hammer" which loosens the deposit. Management of the backflow frequency depends on the fluid being filtered, but enables regular production flows to be maintained over a fairly long period. This practice is particularly well developed in water treatment, with the exception of NF spiral wound membranes, which do not tolerate long-term...
