An economic and novel design is made to remove biological contamination from drinking water. Its upper portion consists of a water filling chamber along with a basic sediment filter and a combination GAC filter impregnated with nano silver colloid. They are in the form of a cartridge and are secured to the bottom of the top chamber. The filter uses two mechanisms to disinfect the water. The first is by filtration; any harmful microorganisms or particles larger than 1 µ m are removed from the water. The second mechanism is by colloidal silver induced antibacterial action. The disinfection rate of this equipment largely depends on the one to one contact between the nano silver ion and the microbe. The microorganisms removal efficiency has been studied extensively and the results are very encouraging to offer a technology at an affordable price tag to the third world countries, where the water borne diseases are a threat to their everyday life. The outline of the study has been published (AWW, 2009).Keywords
