Researchers Developed Eco Friendly Waste-Water Treatment Process
A research that has been done by a research team led by Dr.
Jae-woo Choi and Dr. Kyung-won Jung ultimately developed an eco-friendly
process through which just by using a common agricultural by-product, we can
easily remove the pollutants from water.
We all know that lots of sewage and waste water is produced
from the industrial factories, this sewage or waste water has large amount of
pollutants and environmental hormones commonly known as endocrine disruptors.
As these environmental hormones do not break down easily, they show negative
effects on humans an environment. To be safeguard from these kinds of
pollutants and environmental hormones, it’s became necessary for us to discard
or remove it as soon as possible. There should be a means of removing environmental
hormones.

As per the study published in the journal of Ultrasonic
Sonochemistry, the catalyst that is in use currently to remove pollutants from
waste water is not much effective anymore. Even the existing process in use to
treat the sewage water is costlier. By acknowledging the same, the research
team was mainly focused on the development of single substance catalyst, so
that the waste water treatment process becomes easy and cheaper to be applied.
Rice Husk is the solution
A research has been done on the development of eco-friendly Nano
composite catalyst. The team used rice hulls, it is the hard protecting
coverings of grains of rice which is generally discarded after the rice
harvesting. By using the rice hulls research team created an eco-friendly and
economical product known as biochar. To
create a Nano composite from biochar, its surface was coated with nano sized
manganese dioxide.
The biochar and manganese dioxide both are advantageous and
hence collectively the nano composite obtained from both is more efficient plus
low cost.
Now to check the efficiency of the newly invented process in
comparison to the method which was used since long time, they performed a test.
In this test they used both the processes in the same conditions and found out
that existing catalyst can remove only 80% of environmental hormone whereas the
new developed catalyst removed over 95% of environmental hormones that too in
less time.
Accordin to Dr Kyung-won Jung, “The catalyst developed
through this study makes use of a common agriculture by-product. Therefore we
expect that additional research on alternative substances will lead to the
development of catalysts derived from various types of organic waste biomass”.
