Demineralisation

That's quite a word.
But that's exactly what is done in this building.

The potable(drinking) water we all use at home contains a lot of minerals and cannot be used to feed the boilers.
For instance calcium deposits in the boilerpipes and causes corrosion which can be disatrous.
Also it can deposit at the blades of the steamturbines which has a bad effect at efficiency.
So it has to be demineralized.
As a result of that the conductivity becomes very low also which is an advantage too.
The green vessels in the back contain synthetic resin.
We have two units; each one can produce 50 ton of water per hour.
The plant are fully automatic, after a "run" of 1000 ton the resin has to be regenerated with (amongst other) hydrochloric acid.
The output of the unit is pumped into storage tanks.
