DISSOLVED SOLIDS ANALYZER

摘要

On-line measurements of an amount of dissolved solids in liquid sample are determined by using both conductivity and UV measurements. More particularly, an amount of dissolved solids in a pulp and paper mill process water or effluent is determined by irradiating at least a portion of a liquid sample with ultraviolet light and subsequently measuring an absorption of the light by the liquid sample. Furthermore the conductivity of the liquid sample is measured and subsequently a computation of the amount of dissolved matter in the liquid sample is made from a first relationship between the measured absorption of the first wavelength by the liquid sample and the mesured conductivity of the liquid sample using a suitably programmed processor.
