As technologies develop, experts find more and more pollutants in the world’s oceans, and there’s a wide range of them, from pills and cosmetics to pesticides and petroleum. We’ve been using freshwater bodies of water for dumping chemical and biological wastes for so long, that it will soon be impossible to find a clean river or lake. When Marino Morikawa, a scientist from Peru, learned that the lake from his childhood had become extremely contaminated, he rushed to help.
The urge to save the landscapes of his childhood helped a scientist to make a breakthrough in water cleaning.
When scientist Marino Morikawa learned that the Cascajo Wetlands (El Cascajo) he remembered from his childhood had gotten dramatically polluted, he gave up his research work in Japan and came back to Peru. When Marino saw the wetlands with his own eyes, 20 years after his last visit, it looked like “an oxidation pond.”
The waters smelled terrible, and the 150 hectares of the wetlands he remembered from childhood had drastically diminished to 40 hectares. That was the moment Marino realized he had to do something about it.
Holding a PhD in Bioindustrial Science, Marino used all his knowledge in water quality control to invent a new technology that could help him clean El Cascajo. He took his personal savings, borrowed money from several banks, and started his work on this technology that worked wonders.
He came up with a bubbling nano-system which consists of adding a microbubble solution to contaminated waters and using biofilters. “The micro-nano bubble has an electromagnetic field of positive and negative ions that works like a magnet. On the way to the surface of the water, it attracts viruses and bacteria, kind of like catching them in a spider’s web,” explains Marino.
