FIELD: instrument making.SUBSTANCE: method for determining background turbidity consists in extraction of a particle of specified sizes by means of a filter; for that purpose, gravitational separation of particles of a suspension is performed in a laminar flow at the specified stabilised speed of its movement. A device for determining background turbidity includes a filter with the specified mesh size, as well as in-series connected turbulence arrester, a gravitational suspension separation chamber, a measurement system of background suspension parameters, a pump and a stabilisation system of water pumping speed.EFFECT: improving accuracy and reliability of measurements.2 cl, 1 dwg |
