Zero-defect, geothermal hot water
In the Greater Paris region alone, 250,000 homes are geothermally heated, which prevents the discharge of thousands of tons of CO2. Geothermal hot water is now considered to be a natural resource that can serve as a less expensive, better-performing alternative to fossil fuels.
However, using this eco-friendly energy raises a few technical issues.
EXPLANATION
Where does the hot water used for
geothermal energy come from?
Water is collected
deep down inside naturally hot ground-water reserves
It is run through an exchanger
that recovers its calories
It is then used to heat
buildings or supply heat to industrial sites
Finally, it is reinjected
into the place from which it was extracted
Why treat
geothermal water?
Whether it comes from a high-enthalpy well or a low- to medium-temperature well, geothermal water is highly corrosive and very scale-forming in water networks, requiring appropriate treatment.
- Hot water from low- to medium-temperature wells has a particularly elevated load of bacteria and scale, which causes damage to operating facilities. Its corrosive properties complicate its use.
- Water from high-enthalpy sites (over 150°C / 300°F) is even more laden, especially with sodium, limescale, lithium and lead (at levels 10 times higher than those found in seawater).
A comprehensive ODYSSEE solution
Without intervention, geothermal water is not compatible with operating infrastructure.
Knowledge of infrastructure properties allows for the optimization of its management
and the extension of system lifespans. Geothermal network maintenance relies on
a range of dedicated solutions.
The phosphate-free geothermal water treatment range that has multiple certifications* and is compatible with high enthalpy
The first 100% biosourced scale inhibitor
A scale inhibitor that is compatible with low- to medium-temperature circuits
