Polluted water is India's biggest problem, including Gujarat. Water is getting worse due to pollution of houses as well as industries and so is soil.

Polluted water is India's biggest problem, including Gujarat. Water is getting worse due to pollution of houses as well as industries and so is soil. Devangi Shukla, a PhD student from Ahmedabad, said that the biggest and most important solution to this problem has come at a time when the government as well as social organizations are working hard to solve this problem. After five years of research, Devangi has come up with a solution to clean bad water from contaminated water. This biomediation method purifies water at low cost and can be used for drinking purposes.

Purification of contaminated water only by polluted water.

Devangi Shukla, who has completed his PhD, resorted to this contaminated water to purify the polluted water emitted by industrial units. I.e. the identification of bacteria from the same water as the contaminated water is discharged. These bacteria were analyzed, mixed with contaminated water and purified. According to this research.

it is claimed that more than 70% of water can be purified if water is purified by this method. Not only that, where water is discharged there is a big loss of aquatic animals like fish, but according to the new method purifying the water will reduce the loss of aquatic animals.

details have come to light in research on the study of Ph.D.

Dewangi started research on 'Management of Industrial Industrial Wastewater in Gujarat through Bioremediation' from the Department of Life Sciences, Gujarat University at 201 University. He also received financial assistance from the Gujarat Pollution Control Board under the Fellowship for this research. Devangi mainly discharges water from the metal plating industry as well as from the textile and common effluent treatment plant (CETP), where the water of all types of industrial units is treated collectively. I took a sample of it and did research in the lab. Contaminated water usually contains heavy metals with deadly chemicals, which are dangerous to human life. A method of purifying water by removing such hazardous substances from bacteria has been developed.

How to process?

Under this research 25 liters of water samples were taken from Ahmedabad to Vatva, Ovav, Narol area while liters of water samples were also taken from 3 different phases of Gandhinagar and Kalol and GIDC from Rajkot. Water samples were taken periodically during the year 2018-19. From this water Devangi found 160 different types of bacteria, which took 8 months.

 Out of which 12 bacteria were isolated which can give good results, it took years to know the nature of these bacteria. Made 3 groups of 4-4 bacteria out of 12 bacteria. Named D-1, D-2, D-3. Out of these three groups, the result of D-1 was the most positive. Water purification rate was found to be 95% in D-1, 85% in D-2 and 75% in D-3.

One liter of water takes two hours to purify

Dewangi said that the water of industrial units is so polluted that it takes one to two hours to purify a liter of water under this method so that it becomes reusable.

How is implementation possible according to new research?

It is also possible to implement Devangi's research. Currently, instead of discharging polluted water into rivers, it has to be purified by storing it in a large tank. This creates bacteria from the accumulated contaminated water, which is then released into the water so that the water can be purified.

What is the current situation?

The condition of discharged water in industrial units is very worrying. The state currently has about 800 large and 4 lakh small units in operation. The GPCB has set different criteria for each industrial unit, according to which the units have to be refined and dissolved in their plant. While in some places water is purified by CETP. Mixing chemicals in contaminated water also makes the water more polluted. Which can be dangerous for living creatures in the river.

GPCB Will study Devangi’s research in the coming days.

Officials of the Gujarat Pollution Control Board are not ready to speak openly about the research, but the GPCB has said. A senior NA official told Divya Bhaskar that they would study the research on water purification in the coming days and consider what would happen next.
