Optimal for geothermal power generation inline neutralization treatment: Static Mixer 2800

An inline mixer that achieves simpler and more compact drainage neutralization treatment.

Generally, geothermal power generation extracts steam and hot water from deep underground, using the steam for electricity generation. The remaining hot water exchanges thermal energy with rivers and other sources and is reused as warm water for various purposes. However, the hot water contains various compounds, which are neutralized before being returned to the deep underground. Thus, the wastewater generated from geothermal power generation needs to be managed properly by controlling pH and treating it in accordance with legal regulations. To neutralize the alkaline components in the wastewater, an acidic solution is added, and during this neutralization process, the Static Mixer 2800 is employed. Using an inline mixer for neutralization allows for consistent stirring under certain conditions, achieving stable neutralization treatment. Additionally, if the concentration of the injected acidic solution is high, corrosion protection measures for the mixer need to be implemented. Previously, geothermal power plants used the Kenics type mixer, but from a corrosion perspective, they have switched to the Static Mixer 2800. In the case of the Static Mixer 2800, its simple structure allows for more cost-effective manufacturing with special materials (such as titanium or Hastelloy) and fluorine coatings compared to the Kenics type. It is being utilized in the waste alkaline water process.
