An apparatus for and a process of detecting pollution in an aqueous medium.

摘要

The invention concerns apparatus for detecting pollution of an aqueous effluent by soluble organic or inorganic compounds. The apparatus contains a sampler (19), an effluent reservoir (17), a clean water reservoir (11), a thermostatically controlled bath (15), a coalescer (1), a charcoal filter (2), a differential refractive index detector (3) and a U.V. detector (4). Effluent is intermittently sent through the apparatus from its reservoir (17) and at other times clean water of known purity is sent from its reservoir (11) through the apparatus. A comparison of the readings obtained in detectors (3) and (4) enables one to determine qualitatively the presence of soluble hydrocarbons and organic and inorganic soluble products in the aqueous effluent.
