Bengaluru: Pollution in water bodies is a big issue. 

As human beings use plastic and dump them, they get collected in water bodies, thereby making marine life the ultimate casualty. 

However, there have been continuous efforts to clean up the water bodies. 

One such is floating trash barrier (FTB) which deployed in Cooum river in Chennai in 2017, as reported by India Times. 
The website adds that this solution caught 22,000 tons of floating trash, of which 10 percent was plastics in 2018 alone. 

Attributed to one man, the cleaning agents were able to catch 100 percent surface plastics in the river. 
What is to be noted here is that once the plastic was arrested, it was disposed of in a manner friendly to the environment. Else, one might shudder to think that the plastic would have ended up in the sea. 

So what are floating barriers? 

The website adds that they guard a river, using the flow of water. While they arrest solid water, they also allow the water to pass through them. 

It is to be noted that though it appears to be a very simple design, this combines the best of hydrostatics and hydrodynamics. Made of steel and aluminium, this approach withstands the test of heavy monsoon currents as well, the website adds. 

Once the plastics collect at the riverbank due to these barriers, they can be gotten disposed of easily. One can bring in trucks and collect them at the riverbank.
