Water Purifying Technique in Uranium Zones
Published on by Water Network Research, Official research team of The Water Network in Technology
Yogi Vemana University (YVU) has developed a technology for purification of the ground and surface water by removing radioactive and chemical contaminants like uranium, radium, cadmium, arsenic, calcium and molybdenum
The uranium thus removed from water can be utilised for generation of electricity in nuclear power plants while other mineral impurities can be recycled. It will also keep the environment free of radioactive pollutants released during milling at uranium mines.
Kadapa district in AP and Nalgonda district in Telangana have considerable deposits of uranium. Mining has been going on at Tummalapalle village in Kadapa district, while the Uranium Corporation of India Limited has proposed to take up uranium mining at Lambapur-Peddagattu in Nalgonda district. Various studies have revealed that the ground and surface water at many places in these districts is contaminated by uranium. Certain villages have several times more concentration of uranium pollutants in ground water than the maximum permissible limit fixed byWorld Health Organisation.
Raghu Babu said that uranium deposits of Tummalapalle has been found to have possible solubility in water. The mine effluents along with other heavy minerals also make into the ground and surface water. Besides uranium, the team has also found minerals like molybdenum, arsenic and radium dissolved in ground water. "The uranium extracted from water through our technique is found to be 100% pure," he claimed.
