Abstract
In the well tube precipitation and scaling occur if the physical-chemical equilibria of the components dissolved in thermal water are disturbed partly due to cooling, but largely to the drop of pressure and subsequent gas evolution. All the known methods for the prevention of scaling have some disadvantages. This paper describes a novel technology which is economical and environmentally sound. Supersaturated Ca(OH) 2 suspension is pressed below the bubble point of the well tube and induces CaCO 3 precipitation. A unique feature of the process is that it takes place in the presence of excess acid since below the bubble point all CO 2 is dissolved in water. The pilot scale experiments resulted in products of industrial use.
