Ready to drink water, now days are coming more and more common to us. It can be as a point of use water treatment system, or for a bigger capacity it can use 1 unit treatment and adding a field water disinfection technique at every point of use. The objective of these personal devices is to render unchlorinated water potable (i.e., safe and palatable for drinking purposes). This treatment can also be used to treat safe municipal water for aesthetic purposes by removing chlorine, bad taste, heavy metals like lead and mercury, and odors.
