Stabilization Treatment of Geothermal Water

Summary

Stabilization treatment of geothermal water with the help of degasification and with the use of a crystalline initiator are considered. The experience of operation of geothermal equipment in the case of disturbance of carbonate-calcium equilibrium in water is presented. Degasification of geothermal water treated preliminary for carbon dioxide up to the equilibrium value makes it possible to speed up crystallization of calcium carbonate in the contact medium. It is proved that the more is the drop of pressure in a crystallizer the more is the concentration of a suspension being generated. The speed of separation of the solid phase of calcium carbonate from the geothermal water solution is proportional to the component of the pressure drop in the crystallizer from equilibrium to the final value.

Key words:

suspended substances , geothermal water , degasification , calcium carbonate , salt precipitation , softening
