Abstract
Methods of conditioning a membrane utilized for water purification are provided. The methods monitor membrane performance during water purification or membrane conditioning via fluorometric measurement. The monitoring allows for the detection of removal efficiency of the fluorescing substance. A conditioner is introduced in the feed stream to increase the detected removal efficiency of a fluorescing substance by the membrane. The conditioner generally extends the useful life of the membrane being conditioned.
