Compilation of experiences against the water purification through the use of filters
Main Article Content
Abstract
This article exposes a bibliographic review of cases of study that evidence the importance of the implementation of filters as an alternative for the purification of the water. Five cases applied in Colombia are presented where water purification filters were used —sand filters, clay, ceramic candles and ultrafiltration, among others— in vulnerable communities and two international cases that emphasize the importance of the filters inside the rural communities, where the access to drinkable water can be null sometimes —the used filters were made of sand and ceramic with colloidal silver—. It was evidenced that the use of filters to purify water in the vulnerable communities has a good acceptance and replication given that the access to drinkable water, in these cases, is limited or null.
