Researcher from Toronto warns at UPCT of ending fishing in lakes and seas with excess nutrients (15/05/2017)

Manuel Álvarez Cuenca, director of the Laboratory of Water Treatment Technologies at Ryerson University in Toronto, Canada, teaches today and tomorrow lectures at the UPCT on water treatment technologies contaminated by excess nutrients.

Álvarez Cuenca explained this morning at the School of Roads and Mines of the Universidad Politécnica de Cartagena (UPCT) the applications of the Multi-Stage Vertical Bioreactor that has been patented for the elimination of nutrients in contaminated waters.

The researcher has described how the bioreactor is able to remove more than 93% of ammonia and phosphorus present in contaminated waters.

The laboratory he runs is building a 20,000-liter experimental facility in Toronto, where UPCT students are expected to pass "to improve their English and their knowledge of water treatment technologies."

Reducing the excess nutrients that reach the Mar Menor or purifying the slurry generated by the pig farms to reuse their waters are some of the potential uses that this new technology could have, says the researcher at the Politecnica Ángel Faz, organizer of the talk Carried out within the framework of the Doctoral Program in Technology and Modeling in Civil, Mining and Environmental Engineering.

The researcher recalled that water pollution from excess nitrates and phosphates is a global phenomenon, worsened by climate change.

"For decades we have had this problem in the Great Lakes, between the United States and Canada, while in the Gulf of Mexico, 30% of the water is without dissolved oxygen, so it does not produce life and is the end of its Marine ecosystem and the fisheries and seafood that live on it, "he has described.
