A young genius from Mexico discovered a simple method to purify water inspired by ancient traditions.
Shirley Kimberly Enriquez, a student of Engineering in Energy and Sustainable Development encouraged a way to keep bacteria away and also clean the water of mineral salts and metals such as selenium and lead.
"I started to investigate this technology thanks to my grandmother," said the Mexican researcher, who discovered a way to purify water much simpler and cheaper than traditional methods.
The technique is based on an ancient custom of the Mexican communities of the 19th century, which used pieces of nopal (cactus) to remove contaminants from the water.
According to UNAM Global, the process is achieved by dehydrating the cactus to obtain the mucilage, which is done through a solar stove. This viscous liquid contained in the leaves is responsible for the purification process.
Then a filtering is carried out, the excess matter is placed in a water bath, and finally the precipitation and drying of the mucilage is carried out to crush it and place it in capsules.
The researchers mixed the mucilage with water contaminated with sediment and bacteria and noticed that, after a short time, dissolved substances in the water began to agglomerate.
Noptec –as they have called this product– is also free of carbon dioxide (CO2) emissions for water purification, as no fossil fuels are used at any stage of the process.
According to laboratory testing by Kimberly, each one gram Noptec capsule is able to purify water of bacteria, mineral salts and heavy metals such as selenium and lead.
