The Delhi Government on Friday announced to set up air purifier at five major traffic congestion points in its first phase of the blue print in order to curb air pollution in the national capital.  This move has been taken on the recommendations of the task force headed by Health Minister Satyendra Jain.  The Delhi Government and National Environment and Energy Research Institute (NEERI) is at the final stage of discussion to set up this mega air purifier in 15 days at five major traffic congestion points, which include Anand Vihar, Kashmiri Gate, ITO, AIIMS/IIT Delhi and Sarai Kale Khan, on a pilot basis.

The government has assured to make all the five set up to be functional within six weeks.  Jain said a mist fountain technology will be set up to at one major intersection on pilot basis, adding this will throw mist in polluted air from recycled water which will trap the dust particle available in the air.   “Mist air pollution technology is very established but has not yet been tried for outdoor air pollution. To try its efficiency, we will test it on outdoor air pollution,” Jain told the media here.

Talking about the solid waste management system, Jain said the Rajghat Power Plant, which is not functional from quite a long time, will be changed into waste to energy power plant. 400 mt/per day waste will be used in the first phase, which will later be expanded to 6000 mt/day.   All phases of this project is expected to be functional by December 2017.   However, no announcement has yet been made on the Odd-Even scheme of the Delhi Government.  The Delhi Government yesterday issued a warning for a “critically polluted period ahead” as the capital recorded its worst air quality since February.

The National Air Quality Index showed that pollution levels were severe at Anand Vihar, R.K. Puram and Punjabi Bagh. The air quality at Dilshad Garden, Dwarka and Mandir Marg stations was “very poor”.  Delhi has been witnessing high rate of air pollution from the past one year.   The Delhi Government tried to curb down the pollution by implementing Odd-Even scheme in December last year.

Air purifier sales spike in India as its cities battle pollution

As the government fumbles over effective measures to curb severe air quality in India’s capital of New Delhi, people are increasingly looking at air purifiers for relief.

Major ecommerce businesses in India are reporting significant surge in the sales of air purifier units in the country. The product category, which has existed in India for over two decades but struggled to become a household name, has suddenly become a talking point among people on social media.

Amazon India says it sold three times more air purifiers this Diwali compared to the previous month. Almost half of all these orders came from cities such as Delhi, Gurgaon and Bangalore. Flipkart had similar findings, noting that it has seen 2.5 times growth in air purifier units sale compared to last year.

The sudden interest in air purifying products among people comes as several Indian cities report of increasingly growing air pollution after Diwali. The festival of light, which sees many people burst crackers, combined with the burning of farmlands and residual fodders in nearby states, have resulted in an unprecedented severe air quality in New Delhi and several other states in India.

Five days after Diwali, for instance, the air quality index reading of the national capital is still classified as “hazardous”. A report on UNICEF published this week found that over two billion children worldwide breathe polluted air. India and China were among the most affected countries.

Not just air purifiers, but people are also actively looking for air masks for immediate comfort. “Sales of pollution masks have jumped 6X in the last few days with customer demand being 13X over last year. The highest number of orders for pollution masks were placed by customers on Nov. 1. The demand continues to be high from northern India with most orders coming from Delhi,” an Amazon India spokesperson told Mashable India. The surge in sales happened a couple of days after Diwali, which fell on Oct. 30 this year.

Outdoor air purifier project gathers dust

While the Delhi government is considering installing outdoor air purifiers at traffic intersections, it turns out that the last time the city experimented with such a project, it was left hanging for five years.

The New Delhi Municipal Council had set up an air filtering station in 2010, before the Commonwealth Games.

The purifier was installed outside Palika Bazaar in Connaught Place free of cost by a company called System Life on March 6, 2010. The machine cleaned 10,000 cubic metres of air every hour for about 18 months. The system worked by cleaning polluted air of particulate matter and gases with fabric filters, active carbon cartridges and electrostatic filters.

According to System Life India director Dhruv Chanana, the machine was operational till October 18, 2011, before being removed. “It was removed because no one wanted to accept the need to clean the air,” said Mr. Chanana, adding that had the NDMC gone ahead with more such purifiers, the pollution levels in the area would have reduced. That being said, the authorities have remained mum on the effectiveness of such a project.

Dr. P.K. Sharma, NDMC’s Medical Officer of Health, said it was a pilot project and had not received the necessary approvals to continue. “It was a free demonstration by the company. Before continuing with the project, it required clearance of the Central Pollution Control Board and the Delhi Pollution Control Committee. We are yet to receive that,” said Dr. Sharma.

95% efficiency

The air samples from the trial were analysed by three Italian scientists, including from the University of Modena. Their report was submitted to the NDMC and subsequently to the DPCC.

According to the report, a copy of which is with The Hindu , a total of 2.12 kg of particulate matter had been detained in 860 hours and the filtering efficiency of the system was 95 per cent.

The report concluded that with an “appropriate number of systems” (about 22 for Connaught Place) the air quality of an area could improve.

The DPCC, which works under the Delhi government’s Environment and Forest Department, for its part, did not make any comments on the efficiency of the system, as per a letter sent by one of its scientists to System Life on October 12, 2010. According to the letter, a copy of which is with The Hindu , the DPCC had not commented on the report “as no specific study was undertaken” by it.

Environmentalists, however, used the experience of the NDMC project to question the AAP government’s proposal to install outdoor air purifiers. Anumita Roychowdhury, the head of the Centre for Science and Environment’s air pollution and clean transportation programme, said air purifiers worked within confined environments, “but outdoor air is a complex chemistry with dynamic movement pattern”.

Multi brand air purifier “on the black list”

The winter is coming, haze also changes with the seasons, your home air purifier safety performance? How?

Recently, the National Quality Inspection Bureau, Beijing Consumers Association and other departments concerned about the air purifier product quality performance, quality inspection report released the air purifier and the comparison of the test results. Consumers in the purchase of air purifier, safety performance not only pay attention to the product, to avoid the risk of leakage, but also from the angles of comprehensive consideration of purification efficiency of air purifier, choose their own products. Multi brand products are unsafe household appliances as air purification device, its safety performance must be guaranteed, but the 2016 air purifier national product quality supervision and inspection results of special release in the country General Administration of quality inspection in October 19th showed that many batches of product safety, EMC project failed, to touch the live parts The protection, leakage current and electric strength and working temperature, leakage current and electric project, EMC project unqualified, continuous disturbance voltage of 8 batches of substandard, continuous harassment power of 4 batches of substandard. The unqualified products related to “novowater”, “Yusana”, “sheeraire” seats “” Morrell, moral “,” refinair “,” somputon SIASUN “and other brands.

Similarly, in October 20th, Beijing City Consumers Association released air purifier comparison test results show that the air purifier samples of 50 brands of 50 enterprises in the production or distribution of the 7 samples, there are security risks.

Among them, the brand of” Samsung (Samsung) “model for” air purifier kj250g-k3026pw “(side panel pink)” sign “,” power connection and external flexible cords “project does not meet the national standard. Net U.S. official. The brand product purification efficiency of unqualified consumers in the purchase of air purifiers, are often the most attention. The purification effect of products according to the performance requirements of the national standard gb/t 18801-2015< air purifier “, is from a plurality of index to measure the overall performance. For example, the amount of clean air (called Cadr), purification efficiency, noise, application area, cumulative the amount of purified (CCM) purification, life, standby power, the release amount of harmful substances, removal of microorganisms (bacteria, mildew, bacteria). If these items are not standard, means that the product purification effect on the whole. For example, poor product quality checks the State Quality Inspection Administration issued the results show that the particles of clean air volume 2 batches of substandard particles accumulation amount of purified 1 batches of unqualified, formaldehyde purification efficiency (effectiveness) of 3 batches of substandard, noise of 5 batches of substandard. Among them, the nominal” Beijing net U.S. official Net U.S. official air purifier Environmental Technology Co., Ltd. production (trademark for the “net U.S. official mfresh”, type “m8188a 220V to 50Hz 70W”, “2016-01-25” batch production “) particles clean gas, formaldehyde purification efficiency two project failed. Beijing City Consumers Association released air purifier comparative test results showed that 14 samples did not meet the requirements of the” qualified “purification efficiency level, the brand of” SHARP sharp “, type” kc-w380sw-w “air purifier” formaldehyde purification efficiency “does not meet the standard requirements; sample measurement of noise near 1/5 over express value too much, suspected of misleading consumers.

With mist fountain and air purifiers, Delhi gears up for fight against pollution

The Aam Aadmi Party government said on Friday it will install giant outdoor air purifiers at five highly polluted locations in Delhi, unveiling more measures to battle the capital’s smog.

A mist fountain will also be set up in a yet-to-be identified location, transport minister Satyendar Jain said amid a steady spike in pollution levels, which experts say can cause several ailments ranging from respiratory problems to even cancer in humans.

Jain said the systems, to be installed by mid-December, will be placed at road intersections in Anand Vihar, ITO, Sarai Kale Khan, Kashmere Gate and IIT (Delhi) or AIIMS.

The units works on the lines of a home air purifier by trapping particulate matter, besides improving dispersion of pollutants that remain suspended just above ground in winter.

Experts, however, are skeptical about the system, which has a functional radius of 20 meters and could fail when pollution levels are too high.

Anumita Roychowdhury of the Centre for Science and Environment (CSE) – a Delhi-based research group — said it was not a good idea.

“Purification works in a confined space, not in the open. The government should focus on other short-term measures,” she said.

Last winter – a period when air toxicity jumps manifold -– the AAP government had twice introduced a rationing measure that allowed vehicles to ply on alternate days based on registration numbers ending with odd or even digits. The effort, however, failed to yield the desired results.

An official said the Wind Augmentation and Air Purifying Unit (WAYU) — developed by IIT Bombay and National Environmental Engineering Research Institute (NEERI) – can potentially reduce particulate emission by 40%-60% during peak traffic hours.

The government believes the move will indicate its intent to improve Delhi’s air quality which is expected to deteriorate with farmers in neighbouring states such as Punjab and Haryana starting their annual crop residue burning.

On Friday, particulate matter (PM) level in Delhi’s most polluted zone — Anand Vihar — touched 960 micrograms/cubic meter against a safe level of 60.

The System of Air Quality and Weather Forecasting and Research (SAFAR) also said in its Diwali forecast that PM 2.5 — minute particulates that penetrate the lungs and cause breathing ailments — would increase by up to 20%.

Sources said that open air purification is not a tried and tested measure as one system was installed in Hong Kong in April 2015 without much success.

Experts question plan of air purifiers at major Delhi crossings

 

 

Anumita Roychowdhury of Centre for Science and Environment (CSE) wondered what difference would such purifiers make in a massively polluted city like Delhi, considering its radius will be around 20-30 metres only.

NEW DELHI: Experts today questioned Delhi government’s plan to install air purifiers in major intersections and termed it as a ‘red herring’, saying the focus should be on controlling polluting sources.

IIT Delhi Professor Mukesh Khare said no manufacturer of such purifiers have been able to answer the potential capacity, or ‘zone of influence’ of such devices, especially when installed outdoors.

Anumita Roychowdhury of Centre for Science and Environment (CSE) wondered what difference would such purifiers make in a massively polluted city like Delhi, considering its radius will be around 20-30 metres only.

“What the zone of influence (capacity) of such an air purifier would be is an important question that has not been answered by any manufacturer till date. How is it going to be measured?” Khare asked.

He explained that the capacity of a purifier depends on its pumping velocity and density of pollutants in its immediate surroundings.

“If level of pollutants are very high around prufiers, its filter will get choked very quickly and the pressure will drop and its capacity will decrease,” Khare said.

Anumita said New Delhi Municipal Corporation had installed one such device in Connaught Place in 2010 but never released the complete data gathered by it.

“They used to release only the outlet level air quality but not its impact on the surroundings. No one knows how it cleaned the surrounding air,” she said.

She said resources should be invested on controlling pollution at the source, like farm fires, vehicle pollution, construction dust considering these devices are also expensive.

 

What is HEPA Air Purifier?

HEPA stands for High-Efficiency Particulate Air, and is a filter type that’s designed to adsorb air contaminants such as pet dander, pollen, tobacco smoke, mold, dust, and dust mites. It’s used extensively to improve indoor air quality, especially for environments that need to be scrubbed of allergens for people suffering from allergies and asthma.

It’s used extensively to improve indoor air quality, especially for environments that need to be scrubbed of allergens for people suffering from allergies and asthma.

HEPA Filter Definition:

A high-efficiency air filter designed with randomly arranged, fiberglass fibers. Also known as a depth filter, its porous design retains particulates of a specific size (depending on the filter grade), ensuring that they aren’t released back into the environment. Due to the nature of the design, these filters can hold a significant amount of waste before requiring replacement.

High-Efficiency Particulate Air (HEPA) cleaners help scrub indoor air to remove airborne waste. Sometimes these air cleaners combine filtration methods using HEPA in parallel with activated carbon filters, UV lights, and sometimes ionizers to further clean the air.

Jokes and air purifiers: life of Beijingers in the days of smog

 

As with many of the country’s more solemn situations, the choking smog blanketing Beijing since Monday has evoked such wisecracks from social media users making light of the dire air situation.

In the past few days, jokes on the topic have become one of the most discussed threads on China’s largest microblogging site Sina Weibo.

But despite the light-hearted approach to the pernicious atmosphere, the capital’s residents are feeling the impact of what is the most severe bout of smog in Beijing since July.

The National Meteorological Center (NMC) upgraded Tuesday’s yellow alert to orange, the second highest, on Thursday afternoon. It suggested people stay indoors and wear masks if going out.

Dou Chen returned from the UK to China this February. Since coming home, she has suffered from a nettle rash for five months. A blood test found that she is allergic to substances in the air.

“When I travel outside Beijing, my symptoms are relieved,” she said. But in the past two days, the rash worsened.

In the Guang’anmen Hospital, a doctor told her the symptom were affected by the smog.

An unnamed staff member with the Beijing Children’s Hospital told Xinhua although they haven’t seen an obvious rise of patient numbers yet because the smog just started, they were told to prepare for a peak in respiratory problems.

Wang Xia, 34, is a teacher with the No. 25 Middle School. “Whenever persistent smog occurs, more students ask for sick leave,” she said. “In a class with about 40, once more than 10 students left in the afternoon.”

The environment watchdog in Beijing blamed farmers’ burning fields of straw for causing the smog, an allegation doubted by Beijingers.

But Li Lixin, an air pollution treatment official with the Beijing Environmental Protection Bureau, said a satellite test conducted during the summer of 2013 showed a discharge from widespread straw fires could drive up the PM 2.5 reading in Beijing from 110 to 460 micrograms per cubic meter in a few hours.

Still, web users question the charge.

“Agriculture has been a vital industry in China for hundreds, if not thousands, of years, and it is the tradition in rural areas to burn straw after autumn harvest and plough to bury the ashes in the ground as fertilizer,” said a Weibo user nicknamed Sunflower. “But why we didn’t have smog in the past?”

At such criticism, Wang Yu, head of the energy ecology department of the Beijing Agricultural Bureau, admits pollutants were mainly from motor vehicle exhausts, coal burning, industrial production and dust, rather than burning straw.

“But this is the season for burning straw, coinciding with a special climate which features high humidity and lack of wind,” he said. “It was like the straw that breaks the camel’s back, worsening the air pollution.”

Beijing and its surrounding provinces have banned straw burning. And anti-smog measures didn’t stop there.

In addition to the straw ban, the city pledged to replace coal with cleaner burning energy like electricity and natural gas for domestic use. They also hope to curb coal sales and use by the end of 2020, as well as other high-pollution fuels, such as fuel oil, petroleum coke, combustible waste and some biomass fuel.

Beijing has also raised the discharging fees for major pollutants such as sulphur dioxide and nitrogen oxide this year.

Li Lixin noted that it might take time to see the achievements of such measures, but the government has attached great importance to the issue, and people’s awareness of environmental protection has improved.

In the meantime, Beijingers are avoiding the outdoors and doling out thousands to protect themselves indoors.

An old man surnamed Cheng said his friends with asthma and bronchitis would remind each other not to go out in smoggy days.

Wang Xia’s school has stopped outdoor activities for students. “What if we could have air cleaners installed in each classroom,” she said.

According to a Mr. Zhang, a sales representative of electrical appliance brand SHARP on e-commerce platform JD.com, sales of air purifiers almost doubled in the past two days.

Fu Baoling, a retired worker, just bought a purifier for 2,100 yuan (about 342.6 U.S. dollars). “My granddaughter is young, so I bought this especially for her,” she said. “I don’t know whether this is effective or not. I just hope the sky could clear up soon.”
