Countries that top the list of largest number of desalination plants are Saudi Arabia and Kuwait
The resultant waste water of the desalted are saltier than the waters of origin and they present differences of temperature, of pH, of alkalinity and contain chemical substances used during the process of purification. In case of the plants(floors) that work for distillation the spillage represents from 8 to 10 times the water volume purified, whereas in plants(floors) of inverse osmosis the residual volume is minor that in the previous ones (2.5 to 3 times the polished volume) but the spillage has a content in you work out very much major.
Reforestation is a very good solution from the geographical point of view because they're essential to stop global warming and climate change. Floating houses are a original idea but I think it contructing them could be very difficult to carry out. --Rafael 09:26, 26 March 2010 (UTC)
