KADERES

Water Filter project

The access to safe drinking water is limited in Kagera region, especially in the villages. In order to improve the access to clean and safe drinking water of the local community, Kaderes established the Water Filter project in cooperation with South Pole Carbon Asset Ltd. and Basic Water Needs in 2013. Since then, Kaderes is trying to distribute these Water Filters all over the region at subsidized prices to the villagers as well as public institutions such as schools and hospitals.

Water filters are contributing to decrease the number of people infected by water borne diseases such as diarrhea, cholera, giardia, cryptosporidiosis, thypoid and schistosomiosis. Other than making use of the Water Filter the only option for improving water is to boil water or to buy it. This however brings unnecessary financial and environmental costs, such as the cost of firewood.

The Filter

The buckets of the Water Filter are made out of 'food safe' materials so that the material used in the product is safe for food contact and water.

Basically the Water Filter constists of two chambers, one containing contaminated water, which flows through the candle, the basic filter element, in the second chamber. The candle is made of ceramic, including activated carbon and silver particles, also called Tulip technology

The Tulip technology, exists of diatomaceous earth which is treated with nano silver to avoid growth of algae and to avoid recontamination of the filtered water. The filter element contains activated carbon to remove color and improve taste and smell of the water. This combination ensures that even turbid and highly contaminated water becomes safe and attractive to drink.

There is a removal of harmful bacteria of 99.995%, turbidity removal of 99% and protozoa removal of 99%. Also the silver technology guarantees the safe storage of water. Due to the controlled release of silver particles, bacteria are unable to live and grow in the filtered water, ensuring that the water remains safe for usage for a sustained period.
