Short summary
Mineral precipitation in filters and heat exchangers can impede geothermal plant operation and cause expensive losses of efficiency. To prevent scaling a biodegradable inhibitor has been applied in a geothermal plant. Water monitoring revealed no significant chemical changes, but an adaption of the microbial community as well as a higher abundance of Bacteria after heat extraction. Laboratory experiments under anaerobic conditions showed that the inhibitor can be almost completely metabolized.
