Abstract (en)

[origin: FR2828116A1] A hollow fibre (10) filter module test procedure transmits (16) sound during normal, stopped or back flushing operational mode, from one side of the filter module membrane in a different band or at a higher level to parasitic noises and detects (14) it emerging from a broken fibre on the other side for comparison with a threshold in the same frequency band. An Independent claim is also included for equipment using the procedure.
