property of water is that it is an excellent solvent. This is because of the chemical composition and physical attributes of water. Since water is polar‚ it allows water molecules to become attracted to different molecules. The attraction can be so powerful that it can disrupt the attractive forces of the different molecules.

Business Opportunity Originated‚ Screened and Confirmed Viable: Water desalination is the removal of salts and dissolved solids from saline water (brackish or seawater)‚ also known as Desalting or Desalinization. In addition to the removal of minerals‚ the process removes most biological or organic chemical compounds. Desalination systems have been used to supply potable water for coastal communities and urban centers in more than 40 countries. Desalination plants operate in almost all of the world’s
