Claim 1:
2. A membrane defect inspection method for a membrane separation apparatus comprising a plurality of membrane module sets comprising the plurality of membrane modules connected in parallel under the gas detection piping, the method comprising:
the gas injection process being performed while the water is filled in gas detection large piping communicating with the gas detection piping and collecting the gas emitted to the gas detection piping in the whole membrane separation apparatus; and
a gas accumulation detection process where an accumulation of the gas in a transparent portion of the gas detection large piping is detected, wherein
the membrane defect inspection method for the membrane module set according to claim 1 is performed when the accumulation of the gas is detected in the gas accumulation detection process.
