BENGALURU: Intrigued via the frothing of Bellandur Lake on his method to faculty, a second-year undergraduate scholar with MVJ College of Engineering, Whitefield, has get a hold of a filtration process the usage of fruit peels.
Pavan A, who is learning aeronautical engineering, examined the method at the lab of the Karnataka State Pollution Control Board. The results published that the treated water was once fit for home uses rather than consuming.
The KSPCB lab certificates, a duplicate of which is with TOI, stated that Pavan’s filtration process had introduced down the pH level of the lake water from 6.8 to four.08, fluoride content from 3.3mg/l to 0.27mg/l and phosphate from 23.5mg/l to two.75mg/l.
“Frothing and hearth in Bellandur Lake fearful me each and every time I crossed the stretch or read about them in the information stories. About eight months in the past, I considered doing something about it as an alternative of simply blaming factories of polluting the lake,” mentioned Pavan.
During his analysis, he analysed that at the side of volatile components in business effluents, the lake water additionally had fluoride and phosphate contents from household waste like detergents. “Ultimately, all this was once leading to fireplace too,” he added.
After going through a number of analysis journals, Pavan accrued peels of banana, pineapple, watermelon, citrus lemon and papaya from within sight juice stores for two days and sun-dried them for two weeks. “The peels were then transformed into powder, the usage of whihc I created a number of membranes. These were then activated with the assistance of hydrochloric acid prior to filtration process,” Pavan explained.
It took an afternoon for 5 litres of water accrued from Bellandur Lake to filter out in the course of the membranes. The treated water, Pavan mentioned, was once found to be usable for home function, but no longer for consuming.
Speaking of his long-term plan, Pavan mentioned, “Currently, I'm planning to create synthetic membrane with the assistance of nanotechnology. A thick layer of those membranes may also be laid on the lakebed to treat the water and make it usable.”
