  • Not doubting your word, something doesn’t add up.

    There are hotels in my country that already buy and install dessalination plants, in order to save costs, to fill pools and fountains and even irrigate gardens.

    These instalations have steep requirements to be installed and the off products can’t be dangerous for return to environment, as the return often goes directly to the sea, through beaches.

    Concentrating the salt is also another intelectual itch for me. We naturally concentrate salt by evaporation. There are a few programs aimed at developing low energy/high efficiency processes to obtain salt from sea water. The few I was described involved using systems built around the pressure cooker working principle or purpose built enclosed systems alike to greenhouses to force the water out. I’d risk the processes would be useful to make use of the brines.






  • Where I live, the prices would be for about €1/cubic meter. That is very low. And it wouldn’t hurt farmers to be a bit more conscious on how they use water. There are still to many people that irrigate by flooding, which is demontrated as a bad practice.

    The brine problem I really don’t understand it.

    Nowadays, industry buys salt, processes it to remove rare metals and elements and sells back the purified sodium cloride we buy from shelves (don’t buy it; go for raw salt if you can) or ship it to other industries to be used as a filler (like powdered laundry soap).

    The brine can be as easily processed into these same end uses.
