To clean contaminated water for farmed fish,
drinking and other uses, scientists are now turning to mucilage or inner 'guts'
of cacti. Have a look at the video below
Dr Norma Alcantar, the
lead researcher from University of Florida says “The mucilage
also attracts sediments, bacteria and other contaminants. It captures these
substances and forms a large mass or ‘floc’ that sort of looks like cotton
candy. For sediments, the flocs are large and heavy, which precipitate rapidly
after the interaction with mucilage.” The technology grew from century-old
knowledge that mucilage from some common cacti can clean drinking water
