You could continue cycling the water, filtering out contaminants, without extracting heat from it.

    You can’t really filter this stuff out - it’s things like dissolved magnesium, iron, silica, boron, arsenic, etc. at least not without making it uneconomic I believe.

It’s the nature of water contacting hot rock.
