METHOD OF DETERMINING OIL CONTENT IN WATER STREAM Russian patent published in 2005 - IPC

FIELD: water treatment.

SUBSTANCE: invention, which can be used for continuously controlling quality of water and to measure concentration of emulsions, resides in that, in the calibration step, one performs nephelometric measurements for several different scattering angles, e.g., 30, 60, 90, 120, 150, 180°, in a closed hydraulic circuit, while consecutively increasing oil content in circuit and, each time, dispersing oil in water over a period of time long enough to achieve maximally possible change in dispersity of the emulsion. Values of specified concentrations and current light scattering intensities for different angles are continuously recorded to be further used for educating artificial neuronet, on input neurons of which light scattering intensities for different angles are given and, on output neuron, searched concentration values are obtained. Nephelometric equipment with, contained therein, educated neuronet is used to continuously control content of oil in water stream.

EFFECT: increased accuracy and rapidity of measurements.
