until the overflow water meets the required water quality.

Constantly  monitor  filtrate  water  quality  during 
filtration, and stop the operation if abnormal water 
quality is detected.    If  abnormal water quality is 
detected,  check the integrity of  the element with 
PDT (Pressure Decay Test) or DAF (Diffusive Air 
Flow) Test.    The test procedure is provided as the 
technical information by Toray.
