PQUA system makes waste water drinkable 'in minutes'

Engineers in Mexico say they have developed a technique for purifying sea water, or waste water from households or industrial facilities, in less than two and half minutes.

The system, called PQUA, is capable of separating and removing contaminants, as well as organic and inorganic pollutants, according to researchers.

“The methodology is founded on molecularly dissociating water pollutants to recover the minerals necessary for the human body to function properly”, engineers from Jhostoblak said.

After several tests and trials of contaminated water, they developed a method that indicated what types of predetermined combinations could be made to purify water in real-time.

The residual water in the pilot plant is pumped in the reactor tank to eliminate solid, organic and inorganic matter, as well as heavy metals. The water is subject to molecular dissociation and then conducted to a clarifier tank to remove any excess charge of dissolved elements.

The liquid then reaches a filter that measures clarity and is finally passed through a polishing tank that eliminates any smell, colour and flavour. Once the water treatment is complete, the liquid should be clear and with a neutral taste.

“We have done over 50 tests on different types of wastewater and all have been certified and authorised by the laboratories of the Mexican Accreditation Agency," said the company in a statement.

“Also, the Monterrey Institute of Technology and Higher Education, the College of Mexico and the National Polytechnic Institute 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.”
