The natural cycle of water

Speaking of brine – A question of balance

All the freshwater we consume will one day flow back into the sea via rivers or direct discharges (see figure). The only question is when, where and in what quantity.

It is important that the water withdrawn as part of the desalination process does not lead to local destabilization of the salt equilibrium while brine is being returned.

The dimensioning of the TEXEP Aquaviva stations and the amount of freshwater produced, or brine recycled, ensures that natural dilution takes place. In this way, there is no local salt accumulation and no negative impact on marine flora and fauna.

André Posnansky: “Brine is only water with an increased salt content and is harmless, as long as it is returned to the sea in smaller quantities in a decentralised manner.”
How the TEXEP Aquaviva desalination station is part of the water cycle
Since the used freshwater will one day be returned to the sea, the brine produced during desalination must also be returned to the sea, provided that local dilution effects allow this and the equilibrium is maintained.

André Posnansky: “Climate change is one of the biggest challenges facing humanity today. We want to actively contribute to sustainable freshwater production by powering our desalination plants with solar electricity.”
