Water treatment plant

A treatment plant for water to be treated, comprising:

• at least one storage container configured to store the water to be treated,
• at least one evaporator configured to evaporate the water to be treated into vaporized water,
• at least one condenser configured to condense water evaporated in the evaporator into condensate water, wherein the condenser is fed on a cooling water side with water to be treated, which is flowing to the evaporator,
• wherein the storage container is arranged above the evaporator, and
• wherein the condenser is arranged at a level of a base of the evaporator,
• wherein the storage container is configured to be closable in an airtight manner and openable with an outlet into an overflow pot, a surface height of which is arranged slightly below a vapor outlet of the evaporator, and
• wherein the overflow pot is connected to a cooling water inlet of the condenser, and
• wherein a cooling water outlet of the condenser is connected to an inlet of the evaporator.

A process for the treatment of water to be treated, comprising the following steps:

• unpressurized preheating of water to be treated in a condenser on the cooling water side,
• evaporating the preheated water to be treated in an evaporator into vaporized water,
• passing the vaporized water through the condenser on a condensate side to form condensate water,
• storing the condensate water condensed in the condenser as distillate in a pressure-tight distillate tank,
• oxygenating the condensate water as distillate at a pressure between 100 bar and 300 bar by oxygen obtained from a previous electrolysis of part of the condensate water.
