Abstract
A system and method for purifying water in large quantities for drinking. The system comprises a housing having a water inlet, filtering means connected to the water inlet for filtering sediment and particulate matter from the water, an inlet pump to keep the water flowing through the housing at a predetermined pressure and a mixed bed multimedia unit connected to the filtering means for removing pollutants and controlling organic growth from the water. There is also an ultra-violet treatment means connected to the mixed bed multimedia unit for subjecting the water in the system to ultraviolet radiation and carbon block filtration means disposed for a final filtering prior to dispensing the water at one or more dispensing. There is also a bottle washing means provided within the housing for cleaning water bottles prior to filling with the purified water. The system can supply drinking water for entire communities, yet is portable enough to be easily transported to disaster areas.
