  • Delhi to get India’s first ever recycle wastewater treatment plant, after it became significantly popular in Singapore and Orange County
  • Sujala Dhara plant set up by Absolute Water, in collaboration with Delhi Jal Board and SANA
  • Non-potable use of the treatable water to be promoted extensively by Delhi Government

New Delhi, August 3, 2017: The capital has been suffering a water crisis for a while now, it was only a while back that a report warned the residents that 70 percent of the water in the capital was polluted and unfit to drink. After the spike in the industrial pollutants in the Yamuna river forced the Delhi Jal Board to take action by cutting 50 percent of water supply from two major water plants in Delhi.

After the reports were verified, it was evident that most of the water that the locals were consuming was diluted wastewater. There have been many short term preventive measures already been taken but in the long run, people are still unwilling to consume the recycled wastewater, even though half of the consumption currently is polluted by industrial and chemical waste.

The founder of Third World Center for Water Management said in an interview that, in Singapore, over 50 lakh residents have accepted it as a solution. Dependent on Malaysia for up to 50 percent of its water, Singapore decided that it was better to be self-reliant. With this ‘NEWater treatment plants’, it has not only managed that but also become a hub for advanced water research. A similar effort is also being done on an extensive scale in Orange County Water District in the US.

Rahul Jha of Absolute Water, the water wing of Chemical System Technologies says that “Astronauts do it abroad stations”, Absolute Water develops technology which renders wastewater into potable water. In collaboration with Delhi Jal Board and Social Awareness, Newer Alternatives (SANA) they have established a plant called Sujala Dhara, at the Keshopur Sewage Treatment Plant in July 2015. At a cost of Rs 55 lakh, this plant can produce over 4000 liters of clean water every hour. The plant will be monitored by Delhi Jal Board, while agencies like Central Pollution Control Board have already given it a go.

The wastewater purification process not only reduces the waste discharged into the river bodies but also amounts to 15 percent of raw water remaining after purification, which is rich in nutrients like potassium and nitrogen and can be used as a liquid fertilizer. Even though the people are not yet accepting of this method of purification in India, and the practice won’t be as widely popular as it is in Singapore but the recycled water can be used for domestic needs.


Future Drinking Water

Work is initiated to supply the plant water to Keshopur Bus Depot for washing vehicles. The water will also be provided to the residence of Delhi Jal Board officials who live close to it, and where work on the dual piping system is proposed. So, two completely separate systems will be used to supply potable and recycled water to the users.

While there isn’t much heat on the aggressive consumption of recycled wastewater for drinking, but the Delhi’s Master Plan 2021 is already underway to promote extensive use of treated water for non-potable purposes.

Indian astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal

Indian astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal, equivalent to more than 10 trillion of the sun, and located five billion light years away that could help probe how particles behave under intense gravity and acceleration to the speed of light.

It could help study the role of strong gravity and acceleration of matter in the formation, interaction and evolution of galaxies in the early universe.

Every galaxy in the universe is believed to host a supermassive black hole at its centre. In some galaxies, the black hole is actively devouring a large amount of material and shooting a jet of plasma almost at the speed of light towards us. These are called blazars.

OJ 287 belongs to a class of blazars known as BL Lacertae objects which show very rapid and large amplitude flux variations but barely discernible emission line features.

This class of sources emit in the whole electromagnetic spectrum, a rather uncommon phenomenon which requires extreme physical conditions. Hence, a study of such sources tells us about the behaviour of matter in an extreme gravitational field where it is difficult for light to escape from the vicinity of the black hole.

Astronomers at Aryabhatta Research Institute of Observational Sciences, an autonomous institute of the Department of Science and Technology, Government of India, have been monitoring one such black hole system named 'OJ 287' since 2015. This source shows a repeated optical brightness enhancement almost every 12 years.

"The repeated optical enhancement makes OJ 287 very intriguing as this class of sources does not show any repeating features in flux variations. The repeated optical enhancement made the researchers believe that the system hosts a binary black hole," said a release from the Ministry of Science and Technology.

In 2020, the source was very bright at optical and X-ray bands with X-ray flux more than 10 times the normal (non-active phase) flux. This flare was very different as it was not expected in models proposed for this source and thus, indicated a more complex system and physical conditions.

Investigating the extreme brightness shown by OJ 287 at optical and X-ray bands, astronomers led by Pankaj Kushwaha and Alok C. Gupta reported the source in a completely new spectral state.

The team argued that this change of state holds clues to the researcher's quest to understand how matter behaves in very strong gravity and how it accelerates the particle to almost the speed of light -- a feat that is out of the scope of even the most advanced CERN accelerator.

The research published in 'The Astrophysical Journal' tracked the details of changes in optical to the X-ray emission spectrum of the source with time from 2017 to 2020 -- after the second brightest X-ray flare of the source. It revealed how the source gradually started to change its spectral behaviour from mid-2018 to the new spectral state in 2020.

The study included data recorded by the ground-based facility operated by Physical Research Laboratory, Ahmedabad, operated Mount Abu observing facility in near infra-red bands and the space-based NASA's satellites -- the Niels Gherel Swift satellite at optical, UV and X-rays with gamma ray data from the Fermi satellite, the release added.

Tospread awareness about the significance of reading, Rachna Kalra, who hails from Gurugram (Haryana), started the Silent Book Club in the year 2019.

Who doesn't like reading, and that, too, reading along the company of mother nature? Well, this book club is truly a fantasy turned to reality.

As said by a regular reader at the Silent Book Club, “There is something meditative about reading. Sitting quietly with a book, without any distractions, is almost spiritual for me," this exactly is the case with many such readers.
