Effluent e.g. drinking water, composition variability qualifying method for chemical industry, involves attributing probabilities corresponding to total domains of assembly constituted by derivatives and qualifying composition variability

摘要

The method involves determining two derivatives of physico-chemical parameters of liquid effluent, and defining two logical domains. Probabilities corresponding to the logical domains of the derivatives are attributed. Total logical domains are defined from the two domains where the total logical domains include a normal total logical domain and an abnormal total logical domain. Probabilities corresponding to the total domains of the assembly constituted by the two derivatives are attributed. Variability of the effluent composition is qualified from the total probabilities. An independent claim is also included for a device for monitoring the variability of an effluent composition, comprising a memory unit.
