In the dry-steam power plan in figure.1 the dry steam is piped directly from the well to the power plant where it enters a turbine.

In a flash steam power plant in fig.1 The very hot water flows up through wells under its own pressure. As it flows to the surface, the fluid pressure decreased and some of the hot water boils or “flashes” into steam. The steam is then separated from the water and used to power a turbine/generator unit. The remaining water and condensed steam are injected through a well back into the reservoir.

The temperature of the water in a binary-cycle power plant is:

Some of the solid waste in geothermal plants can be recovered and recycled for other industrial uses. Some of the examples could be Silica that can be used in industry as a raw material and elemental sulfur, which is recycled for sulfuric acid production.

For more than a decade now 3 companies and one community in California have received awards for their outstanding environmental performance from the use of geothermal power.
