Martin Bolton's ‘Rural Water Filter' is Superb

To improve the quality of water in developing countries like Africa, Martin Bolton came up with a low cost water treatment design that utilizes colloidal silver in a ceramic filter.

Bolton’s ‘Rural Water Filter’ features a ceramic filter coated in colloidal silver. The colloidal silver has antibacterial, disinfecting qualities in ceramic that make it quite promising for a water treatment design.

The Master’s project at the University of Johannesburg has not yet been published, but it is an important concept helping to resolve health issues in many developing countries and war-torn zones.
