The primary reason behind the formation of toxic foam in Yamuna is high phosphate content in the wastewater because of detergents used in dyeing industries, dhobi ghats and households, according to officials. How to achieve goal The DJB claimed to be on a war footing to ensure this. The department has taken up several measures. According to officials, Delhi at the moment has four major sources of pollutants affecting Yamuna — Sewage Treatment Plants STPs , untreated water from unauthorised colonies, sewer water from authorised colonies and interstate factors involving Uttar Pradesh and Haryana.
To treat sewage water at STPs, the DJB is adopting a five-step method of intervention so that the water quality is improved. Dosing of coagulant: In this, alum is used to remove suspended solids in the STPs because at present, the solids getting dissolved is 60 per cent and with the use of alum, it will be 80 per cent.
The particles supposed to be treated as per the National Green Tribunal are currently not designed. Restructuring is being done so that these can treat BOD and ammonia as well. It basically acts as a house for growing bacteria that makes the water cleaner. The more bacteria, cleaner the water. In most cases, it is the last stage in the pretreatment of water for removal of un-dissolved impurities prior to treatment by Ion Exchange or Reverse Osmosis.
Disk filters: This is constructed by using numerous flat, grooved disks stacked tightly on top of each other and contained inside a casing. Water flows into the filter casing, surrounds the stacked disks and is forced through the grooves by pressure, removing the filtered material. This help removes ammonia and maintain the NGT water parameter. Incineration: This is high-temperature burning rapid oxidation of waste, also known as controlled-flame combustion or calcination. It is a technology that destroys organic constituents in waste materials.
New techniques are developed for this process, used as energy-generating methods. Neighboring states Haryana and UP were also supposed to spend money on cleaning this river.
Adding all the money spent by these three states, it comes to Rs crore. The result: the Yamuna continues to be a river of filth in Delhi.
The Yamuna Action Plan was implemented way back in Twenty-eight years have passed and the Yamuna is still a river filled with garbage. Tiwari demanded that the Supreme Court should take suo motto cognizance of the fact and seek accountability from the Delhi government.
On the frothing of Yamuna river at Kalindi Kunj, Raghav Chadha said, water filled with huge amounts of surfactants falls into Kalindi Kunj from a height, which causes foam.
He blamed the Haryana government for the rising toxicity in the Yamuna river. Chadha has blamed the UP government too. He said, the Okhla barrage near Kalindi Kunj is operated by the UP government, but UP minister Siddharth Nath Singh said, the state government is responsible only for the flow of water at Okhla barrage, and not for treating water. He advised Delhi government to set up more STPs sewage treatment plants so that the Yamuna can remain clean.
Experts say, detergent making factories in Delhi release untreated waste full of phosphatic chemicals which while reacting with acidic water cause foam. This, they said, can be stopped by strictly enforcing National Green Tribunal guidelines. Under the Yamuna Revitalization Plan, it was proposed to ensure the only permissible limit of pollutants in waste being released in the Yamuna, but nothing much has happened during the last two years.
A monitoring committee set up in by NGT was dissolved in January this year. Among the main reasons for Yamuna pollution are low water levels, 18 drains mainly Najafgarh and Barapullah releasing sewage into the river.
The Najafgarh drain also carries waste released by factories in neighboring Gurugram and Manesar. After Wazirabad, it is the Najafgarh drain that falls into the Yamuna, polluting water and lowering oxygen levels.
The question is: what is the Delhi government doing? One month ago, Delhi Pollution Control Committee prepared a report. It says daily MGD million gallons per day sewage water waste is produced in the capital daily. Delhi government claims there are 34 STPs sewage treatment plants working at 20 locations across the capital, which have a collective capacity of treating MGD waste daily.
The report says these STPs do not work to optimum capacity. They can treat only out of MGD of waste daily. It means, 11 percent of waste falls directly into the Yamuna.
Delhi government had told the monitoring committee that its STPs would be able to treat 99 percent of waste by June , but more than two years have passed.
Appearing like snow, the toxic froth is full of residential and industrial waste whose foul stench could be smelt from a distance. On Tuesday, a thick layer of foam could be seen floating on the surface of river Yamuna near ITO area in the national capital.
The froth formed on the Yamuna river due to the release of toxic pollutants into the water body. Attributed to the high phosphate content of the water, the foam is also caused due to the dumping of waste. However, it was now covered with dirt. He added, "The government is doing its own course but we as a citizen should also take steps to combat the situation.
People should not throw the dirt into the river. It seems like sewage is flowing into the river, we need to stop it. In November , d evotees gathered on the banks for the Chhath Puja in Delhi and were met with not just foaming waters but also high levels of toxic pollution that engulfed the city, making it difficult to spot the sun.
