Is it feasible that seawater can be made for drinking purpose?

yes ,but treatment sea water very expensive.

Yes, it can be. but if were using generally used treatment plant equipment's than it can be costly.

So, i have an idea to decrease its cost of treatment. In first stages of treatment we should use indigenous methods of sand and pebbles method along with De-saltation Wells and chambers to minimize its cost of treatment.

Yes, It is possible to make seawater drinkable. The seawater contains dissolved minerals and salts which are harmful for the human body. To remove these minerals and salts from seawater we use a process called "desalination".  This desalination process is helpful to make seawater drinkable.

Yes it is possible by desalination method .

Why not !!! If it is for domestic use one can desaline water in the house.All simple methods for removing the salt from water follow a basic principle: evaporation and collection. There are  several methods that can be used to boil salty water and collect freshwater from the steam or condensation,The most common method is a stove-top method.But if somebody want to do it in huge volume, than the methods are too expensive, which concerns heat.

• Yes by means of Reverse osmosis

by purification process to separates the salt and pure water.
