摘要
A scale suppression apparatus capable of suppressing in a low-priced manner the generation of silica-based scale and calcium-based scale in the influent water, a geothermal power generation system using the same, and a scale suppression method are provided. The apparatus includes a first addition unit configured to add liquid containing a chelating agent and an alkaline agent to influent water flowing through a pipe arrangement to make the influent water higher than pH 7, a second addition unit configured to add an acid substance to the influent water to make the influent water lower than pH 7, and a controller configured to alternatively switch between the operation of the first addition unit and the operation of the second addition unit. The controller controls the switching of the first addition unit and the second addition unit based on the signals output from a scale detection unit and a pH meter.
