20100125422 | Method for Qualifying the Variability of an Effluent Composition - The invention relates to a method of qualifying the variability of the composition of an effluent, in which method a series of measurements is effected over time of at least one first and one second parameter of the effluent. The invention is characterized in that, in each time step, first and second derivatives of the parameters are determined, first and second logical domains are defined, probabilities of the first derivatives belonging to the first logical domains are assigned, probabilities of the second derivatives belonging to the second logical domains are assigned, global logical domains are defined, global probabilities of belonging to the global logical domains are assigned, and the variability of the composition of the effluent is qualified on the basis of these global probabilities of belonging to the global logical domains. | 05-20-2010 |
20090261039 | METHOD OF TREATING WATER EFFLUENT FROM PURGING OR CLEANING STEAM GENERATOR CIRCUITS, AND A MOBILE UNIT ENABLING THE METHOD TO BE IMPLEMENTED - The invention relates to a method of treating water effluent from purging or cleaning steam generator circuits. | 10-22-2009 |
20090221013 | METHOD FOR QUANTIFYING LIVING COLIFORM MICROORGANISMS IN A WATER SAMPLE - The invention relates to a method of rapidly quantifying living coliform microorganisms in a sample of water in which the microorganisms are put into contact with a fluorogenic substrate that is hydrolyzed in methylumbelliferone by an enzyme given off by the microorganisms. Methylumbelliferone is detected by the fluorescence that it emits, with the rate at which this fluorescence varies being measured in order to determine the concentration of coliform microorganisms in the original sample on the basis of the calculated rate of variation and a correlation plot. In characteristic manner, a preliminary treatment step is performed on the sample, in particular pre-filtering, serving to remove at least some of the particles in suspension in the water, thus making it possible to achieve quantification that is entirely comparable with the quantification given by the standardized multi-well panel method. The invention is applicable to analyzing bathing water for detecting | 09-03-2009 |
