Good evening to ...

Good evening to everybody: Dear all. I have entered as a guest few weeks ago and I would like to congratulate you for this interesting article. I was born in Spain in a small archipelago called Canary Islands and many of the situations described above seem familiar to me. In fact, the cost of desalting a cubic meter of water from the sea is very high. Thanks to the inclusion of ERD it has dropped a little bit but it is still a bit high. If you use Distillation Methods to desalinate water you will require a complex system to remineralize the permeate. So by using membrane methods the water quality is less than using distillation but on the other hand their cost will be also fewer. I go along with Jean Marius in considering of waste waters revalorization for a productive organic farming as a valid solution in terms of water reuse. This method together with a good disinfection method (such as Ozone or UV post- treatment) will help you produce potable water with the best warranties of consumption under no risk. Thanks very much for giving me the opportunity to express my own ideas. Best Regards
