Mexican engineers find way to recover waste water in 2.5 minutes

A group of Mexican engineers have devised a technique for recovering and purifying sea and waste water in just 2.5 minutes, researchers say.

The system, called PQUA, has been developed in Jhostoblak Corporate and is capable of separating and removing all kinds of contaminants, as well as organic and inorganic pollutants and is most suitable to recover wastewater from households, hotels, hospitals, commercial, and industrial facilities.

“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,” an engineer from Jhostoblak said.

Through conducting numerous tests on different types of contaminated water, researchers finally managed to develop a methodology that indicate what types of predetermined combinations should be made to recover and purify water.

Solid, organic, and inorganic materials, as well as heavy metals, are eliminated by precipitation and gravity through pumping the residual water of the pilot plant in the reactor tank. There, the water is subject to molecular dissociation and is conducted to a clarifier tank to make any excess charge of dissolved elements sediment.

Sludge settled at the bottom of the reactor is removed and tested to determine if it is suitable for use as fertilizer or construction material.

To remove turbidity, the liquid, then, reaches a filter and is ultimately passed through a polishing tank that removes flavors, colors, and odors. As the final phase, ozone is added to the treated water to ensure its purity and make it ready for drinking. The resulting water should be fresh, clean, and odorless with a neutral taste.

“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… 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," said Jhostoblak Corporate in a statement.
