Water used different applications

Potable water (fresh water) suitable for human consumption should not contain dissolved salts more than 500 ppm. For agricultural purposes, water containing salt content of 1000 ppm is considered as the upper limit. Potable water is required for domestic, agriculture and industries. Some applications in industries like cooling purposes, sea water is feasible despite the corrosion problems while other industries use higher quality water than is acceptable for drinking water. Modern steam power generation plant need water with less than 10 ppm. Potable/fresh water is available from rivers, lakes, ponds, wells, etc. Underground saline/brackish water contains dissolved salts of about 2,000-2,500 ppm.
