As regards energy production by geothermal plants, controlling the fouling and scaling of the equipment involved in the process is crucial to guarantee maximum efficiency of the plant.

The phenomenon of scaling affecting geothermal plants is mainly due to the water used in operations (extracted from deep soil) that contains the following chemical substances:

  • Silica
  • Carbonates
  • Sulphates
  • Metals and earth alkali metals

The precipitation of inorganic salts from the a.m. chemical substances/compounds mainly occurs in water re-injection wells, heat exchangers and surface equipment at lower temperatures.

Bozzetto has developed special scale inhibitors based on the dispersal mechanism of metal ions and inorganic salts, capable of operating under complex working conditions typical of geothermal plants. Bozzetto’s scale inhibitors can be used as such or diluted in solutions, directly in the well.
