The engineer revealed that the entire process of manufacturing, consulting, validation and certification of the device - which is already used, since 2012, by the water treatment company Gotapura - was the result of his own investment.
Affirming that "the goal is not only to serve the domestic market," but to move towards the global market, the Angolan, in statements to the Angolan Public Television (TPA), admitted that it is no longer possible to manufacture the device on a large scale.
For now, the device costs 190,000 kwanzas, but the goal is to start mass production, making the price cheaper and more attractive.
