The most hardworking and promising students of one of the polytechnic schools in Switzerland began work on a unique project.
We are talking about young scientists from the city of Lausanne, who intend to obtain effective fertilizer for farmers from wastewater by trial and error.
Experimental development is carried out on the territory of the treatment plant, which is located in the vicinity of the city of Yverdon-les-Bains. Students expose water from sewage to osmotic distillation.
It is known that in this case two tanks with a capacity of twenty-five liters each are used at once. Using tanks, as well as metal cylinders equipped with a separation membrane, and pumps, the designers drive the water through several stages, after which the membrane releases nitrogen obtained during the distillation process.
It is reported that the concentration of this gas in fertilizers exceeds forty grams per liter. Such indicators automatically classify fertilizer as high-quality.
Experimenters predict a great future for their invention. However, they are not yet distributed regarding the estimated volumes of production and the start date of the sale of the unique product.
