New environmental project uses bacteria to deal with hydrogen sulphide in cooling water used with the Wairakei geothermal power plant in New Zealand.
Hydrogen sulphide from geothermal plants continues to be an issue that geothermal plants have to deal with. So reports about a new environmental project from New Zealand promises an interesting solution.
The project uses bacteria that lives on toxic waste, to consume hydrogen sulphide from the Wairakei geothermal power plant by oxidising sulphide.
The facility is owned by Contact Energy and has been named “bioreactor”.
The plant uses water from a nearby river as coolant but is later pumped back into it. Through the geothermal steam, it picked up hydrogen sulphide which has damaged the aquatic environment of the river.
