A group of Mexican engineers from the Jhostoblak Corporate created technology to recover and purify seawater or wastewater from households, hotels, hospitals, commercial and industrial facilities, regardless of the content of pollutants and microorganisms in just 2.5 minutes.
The system, PQUA, works with a mixture of dissociating elements, capable of separating and removing all contaminants, as well as organic and inorganic pollutants. "The methodology is founded on molecularly dissociating water pollutants to recover the minerals necessary and sufficient in order for the human body to function properly nourished," the researchers explained.
Notably, the engineers developed eight dissociating elements, and after extensive testing on different types of contaminated water, implemented a unique methodology that indicates what and how much of each element should be combined.
"During the purification process, no gases, odors nor toxic elements that may damage or alter the environment, human health or quality of life are generated," said the engineers.
The corporation has a pilot plant in its offices that was used to demonstrate the purification process, which uses gravity to save energy. The residual water in the container is pumped to the reactor tank, where it receives a dosing of the dissociating elements in predetermined amounts.
In this phase, solid, organic and inorganic matter and heavy metals are removed by precipitation and gravity; a sludge settles at the bottom of the reactor. This is removed and examined to determine if it is suitable to use as fertilizer or manufacture construction materials.
Subsequently, the water is conducted to a clarifier tank, to remove the excess charge of dissolved elements; then the liquid reaches a filter to remove turbidity and is finally passed by polishing tank that eliminates odors, colors and flavors. The treated water is transported to a container where ozone is added to ensure its purity, and finally is ready to drink. Indeed, the resulting liquid is fresh, odorless and has a neutral taste.
"We have done over 50 tests on different types of wastewater and all have been certified and authorized by the laboratories of the Mexican Accreditation Agency (EMA). Also, the Monterrey Institute of Technology and Higher Education (ITESM), the College of Mexico and the National Polytechnic Institute (IPN) have given their validation that the water treated with our technology meets the SSA NOM 127 standard, which indicates the parameters and quality characteristics for vital liquid to be used for human consumption," says a Jhostoblak statement.
Moreover, the company reports that this development is protected under trade secret in America and will soon have the same status in Switzerland. Its implementation in the market will depend on the needs of users and the issue of new laws regarding use and consumption of waterdischarge.
