Washington: A Mexican firm claims to have developed a new technique that can recover and purify waste water in just two and a half minutes, regardless of the content of pollutants and microorganisms.
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,” according to engineers from the Jhostoblak Corporate.
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, odours nor toxic elements that may damage or alter the environment, human health or quality of life are generated,” the firm said.
The corporation has a pilot plant in their offices that was used to demonstrate the purification process, which uses gravity to save energy.
“We observed that the residual water in the container was pumped to reactor tank, where it received a dosing of the dissociating elements in predetermined amounts,” the company said.
In this phase solid, organic and inorganic matter as well as heavy metals are removed by precipitation and gravity; and a sludge settles at the bottom of the reactor.
The latter is removed and examined to determine if it is suitable to use as fertiliser or manufacture construction materials.
Subsequently, the water is conducted to a clarifier tank, to sediment the excess charge of dissolved elements; then the liquid reaches a filter to remove turbidity and is finally passed by polishing tank that eliminates odours, colours and flavours.
The treated water is transported to a container where ozone is added to ensure its purity, and finally is ready to drink. The resulting liquid is fresh, odourless and has a neutral taste.
“We have done over 50 tests on different types of waste water and all have been certified and authorised by the laboratories of the Mexican Accreditation Agency (EMA),” the company said.
“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,” said the company.
