Invention uses salt and car battery to purify water

The goal is to make drinking water accessible to poor populations worldwide.

Reserve a little water, add a spoonful of salt and add everything with a little electricity. From this recipe is born a chlorine solution capable of purifying up to 200 liters of water. Who is responsible for the chemical reaction? The SE200 Community Chlorine Maker.

The result of a partnership between an NGO and a mountaineering equipment company in the United States promises to make chlorine an efficient chemical element for water purification – accessible to poor and isolated populations around the world. In this way, they can have easy access to drinking water. According to the World Health Organization, more than 750 million people worldwide do not have access to their own water sources.

To produce chlorine, simply put water and a quantity of salt in a special container that is connected to a 12 volt car battery or motorcycle for a couple of cables. The salt naturally dissolves in sodium and chloride ions and, upon receiving a small electric discharge, the chloride ions oxidize to chlorine. The entire process takes only five minutes.

Concerned about facilitating the operation of the SE200 for underserved populations, Mountain Safety Reasearch, the project manager, also sought to provide a user-friendly interface. Lights flash during the chemical process and a happy face indicates the end of the procedure.

The product is due to launch in May 2016, but has been tested in more than 10 countries, including Kenya, Ghana, India and Haiti.

The equipment should be sold for $ 200 dollars and the company’s product developer ensures that it can provide adequate water treatment to 200 people for 5 years.
