Abstract

The subject matter described herein relates to a water purification device (104) for purification of water. The water purification device (104) includes a filtration unit (116), a primary disinfectant unit (118), and a secondary disinfectant unit (120). The filtration unit (116) includes a plurality of permeable membranes (302) and is configured to filter particulate matter present in the water to provide filtered water. The filtered water is treated by the primary disinfectant unit (118) having at least one metal disinfectant treated porous media (402) to inactivate a first portion of microbial contaminants present in the filtered water. Further, a second portion of the microbial contaminants present in the filtered water is inactivated by the secondary disinfectant unit (120) having at least one oxidizing agent releasing component (502).
