Abstract

In a method for detecting the concentration of a primary and emulsifiable contaminant, e.g. oil, in water which also contains secondary, tertiary and possibly other non-mechanically emulsifiable contaminants, such as iron oxide and/or atapulgite, the contaminated liquid is prepared to repeated disintegration of the primary contaminant in an emulsifier to form discrete, homogenous and precise primary contaminant particles in order to maximize the light scatter effect. The liquid is then passed through a measuring cell and irradiated with light from a light source, wherewith the type of secondary and tertiary contaminants present, which cause the light to be scattered in a significant fashion, substantially in a rearward direction, are determined by a detecting primarily the quantity of light reflected at different angles and secondarily the quantity of light transmitted. The total quantity of the thus determined types of contaminants is determined primarily by detecting the quantity of light transmitted and secondarily by detecting the quantity of light reflected, thereby also enabling the concentration of the primary contaminant to be calculated.
