ABSTRACT
This paper deals with synchronised influences of hydromechanical and hydrochemical parameters on the formation of solid deposits in geothermal and other waters, which compose complex heterogeneous and micro-heterogeneous liquid-solid systems. The constituents of these waters in ionic, colloidal and micro-heterogeneous suspended liquid-solid states are responsible for the creation of carbonates, sulphates and other solid matters. In these processes, one cannot eliminate the influence of hydromechanical parameters with flow velocity and water flow criteria (laminar or turbulent flow) as vital factors. Experiments were conducted on the laboratory pilot installation with glass pipes of 2, 4, 6, 8 and 10 mm in diameter, respectively, and the flow was monitored by using a digital peristaltic pump with the flow rate of 2 ml/min to 5000 ml/min. The paper studies the impact of the linear flow velocity on the relative decrease of the initial water hardness in geothermal waters of Sijarinska Banja spa, Niška Banja spa and the estuary water of Medijana, Niš. From the obtained dependences, according to the linear regression model, for each diameter, critical values for linear velocities were determined, as an important parameter for the understanding of the synergism of the hydromechanical and hydrochemical parameters were determined.
