Desalinization is the process of taking seawater and taking out all the salt in it so it's fit for human consumption.
I want to desalinate this water.
Desalination (to desalinate) means to take out the salt. If you boil salt water, the water turns to gas and leaves the salt behind.
desalinate sea water
easy .. do nothingg
Either you melt ice, or you desalinate sea water.
because it has less rain
As yet is seems that it is not possible to do so. This does not mean that it can not be done.
The excess salt is excreted via the gills.
You cant filter it out. you desalinate water through evaporating the water out of the salt.
None: You can desalinate it, distill it, but you cannot drink seawater.
For the desalination by distillation - the boiling point of water. For other methods the temperature is not so important.
No. You can melt ice or desalinate sea water to obtain sufficient drinking water.
