A process for the preparation of the treated water fortified with the micro nutrients comprises pre-treating and sterilizing the water, resulting in a pure permeate. The said permeate is passed through ozonator for further sterilizing the water and thereafter it is de-ozonated to produce on line sterile water. The treated water is fortified with dosing at least one bio-available micro nutrient and/or sanitizing agent into the flowing water on line. The finished product must conform to the control drink preparation standards.
