Use of the jar avoids application of aluminum sulfate, to toxic nature.
Technique also eliminates bacteria and make water fit for use.
The dark waters of the Rio Negro, Amazonas, need to be clarified and purified before being consumed. One of the products used in this process is aluminum sulfate, to the toxic nature. To prevent contamination and improve the health of communities that depend on river water, the National Institute for Amazonian Research (INPA) studied the use of a seed plant, Moringa, to make drinking water from the Rio Negro and got results Unexpected.
The moringa is a plant indigenous to India. To purify the water is extracted from the seed and masserada, forming a powder applied in the liquid. In Brazil, the plant is already used to take the clay and remove bacteria from rivers in the Northeast. As the amount of dust varies with the characteristics of the rivers and also the time of year, "the research pioneered the INPA," says Edilene Sargentini, pharmaceutical, who participated in the studies.
"The big difference is that the Rio Negro water is colored by the presence of humic substances resulting from the decomposition of plants and animals of the forest, transported to the river through leaching," said Edilene.
In addition to obtaining clear water and eliminate 99% of bacteria, the study of Inpa developed a new methodology for the application of seed jug which can purify the water more rapidly. By applying the powder in water, no need to wait about two hours, as in known processes. In the laboratories of INPA, purification occurred in only a few minutes.
Moreover, with the new method, researchers were able to leave the drinking water for up to three days - one day against the conventional method. "After using moringa seed powder, you have the time to use the water. After that, it 'rot'. We found a new methodology to use this seed so that water does not 'rot' so fast, "said Edilene. The researchers plan to patent the new methodology.
Sachets
Now, research is entering a new phase, out of INPA. The team's goal is to develop moringa pods, which could be distributed to communities on the edge of the Rio Negro with a step by step use. For Edilene, the pouch would facilitate the use of Moringa, because they come with the right dose. Suffice it to put it in water without the need to have the plant in the yard and prepare the powder.
But even before the creation of sachets, search results can be applied through education preparation and application of the powder in water. One of the goals of the research team is to create a booklet explaining procedures.
Although not native to Brazil, moringa has adapted well to conditions of the Amazon, says Edilene. "[In Inpa] we planted 90 seeds germinated moringa and 87. Within a year the plant is already bearing fruit. And if the pruning is done correctly, the moringa seed gives up to three times a year. " Then you can just prepare the powder. A simple solution to improve the Rio Negro and the health of people living around it, Edilene concludes.
