Mineral stones water replacement filter

Mineral stones filters are simple devices made out of clay and used to filter drinking water in order to removes turbidity, suspended materials and pathogens. Removal takes place by physical process such as mechanical trapping and adsorption on the ceramic candles, which have micro-scale pores.Water is poured into the upper of two container and flows through a candle situated in the bottom. Once the water has passed through the candle, it is collected in the lower container. This system both treats the water and provides safe storage until it is used. The filters are easy to assemble and no energy is required. Maintenance includes frequent scrubbing with a brush and proper care during transport and its use. They can be constructed with locally available material, which can contribute to the development of local commerce.The ceramic filter is made of a highly compressed ceramic diatom substance. It has a very tiny porous structure of 0.2-0.5 micron as less than half size of bacteria (0.5-1.0 micron).
