Scientists turn wastewater into fuel



Scientists turn wastewater into fuelScientists experiment in the laboratory.

Sewage from the source of eternal problems can turn into a source of environmentally friendly fuel. Spanish researchers have found that phototrophic purple bacteria can convert human waste products into sewage into hydrogen.

Scientists from the Spanish University named after King Juan Carlos believe that civilization is really drainage in the sewer is very much energy, writes Popular Mechanic. Their research proves that phototrophic purple bacteria can remove nitrogen, hydrogen and carbon from any organic waste. That is, wastewater may be an unreliable source of energy, biochemicals, and even animal additives, writing ZME Science.

Phototrophic purple bacteria can be photosynthesis, as plants. The difference is that infrared radiation replaces visible sunlight. In its presence, bacteria use organic molecules and nitrogen gases to produce carbon and nitrogen, releasing electrons.

Byproduct of such metabolic reaction – – Hydrogen gas that can be used as a fuel.
"In the process of metabolism, purple bacteria experience problems with too many electrons. One way to get extra electrons out – – CO2 repair during photosynthesis, as plants do. Second way – – release electrons in the form of gaseous hydrogen. The electric series allows us to manage and handle these processes, " – – at Puyol.

Research has shown that a mix of increasing nutrients and the hydrogen production rate also reduce CO2 production.

Therefore, valuable biofuels can be obtained from substances that are abundant in wastewater: malic acid and monosium glutamate. And the production process itself leaves a very low carbon footprint: during the experiments, the negative polarization of the electro caused a marked increase in electrons associated with reducing the production of carbon dioxide.

In addition, using existing electrical bacteria, it managed to produce hydrogen from human waste. The process is strongly prohibited in the presence of ammonium, derived from proteins in the wastewater. So, before going on to produce hydrogen, you need to make sure that the composition is purified with ammonium.

Although scientists experiment in the laboratory. But soon they are hoping to experience the technology in large purification plants to make sure they work on such a scale.

In theory, even small wastewater treatment works will be able to provide clean energy from 43 to 107 houses.
