Treatment and valorisation of used natural thermal and mineral waters and sols e.g. after use in remedial baths

摘要

Treatment and valorisation of used natural thermal waters, mineral waters and sols, especially after balneological use comprises: (a) sedimenting the components introduced as a result of the use to which the waters have been put, flocculating out with a precipitating agent, filtering, and subjecting to oxidative treatment e.g. with ozone followed by adsorptive filtration; (b) subjecting the water to reductive treatment and converting into an anoxic medium; and (c) reinjecting the treated water into the geological supply level or similar geological level.
