摘要： Method for detecting transparent exopolymer particles in a water sample. The method comprises step of obtaining a water sample and introducing a fluorochromatic reagent to the water sample. The fluorochromatic reagent is specific to vicinal hydroxide groups of transparent exopolymer particles, whereby the fluorescence signal of the reagent changes when it comes into contact with transparent exopolymer particles, i.e. TEP. Finally the fluorescence signal from the water sample is detected and the TEP level of the sample is determined.

摘要： 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.

摘要： The method for purifying liquids purifies a saline liquid, e.g., salt water, using a plurality of first phase reverse osmosis (RO) units and at least one final phase reverse osmosis unit. The plurality of first phase reverse osmosis units are arranged in series. At least some of the concentrate in a last reverse osmosis unit of the series is recycled back to the permeate or output side of that unit to provide a mixed permeate. The mixed permeate is then passed successively to the permeate side of each preceding reverse osmosis unit in the series. This increases the salt content of the liquid in the permeate side of each phase, thus reducing the concentration differential across reverse osmosis membranes of the first phase reverse osmosis units.
