The air quality has touched the "severe" level four times till now this year.  The peak monsoon months typically see an improvement in the city’s air quality as monsoon winds and rain settle the poisonous particles.Rain has been lashing Delhi for a few days now, but it had failed to give any good air quality because of intermittent spells.3 mm rainfall, more than the 249 mm average. According to System of Air Quality and Weather Forecasting and Research institute (Safar), under Union ministry of Earth sciences, the air quality index (AQI) of the city was recorded at 43, which falls under the "good" category. An AQI between 0-50 is considered good, 51-100 satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor, and 401-500 severe.The meteorological department said that the rainfall the capital has received till now has been 18 per cent in excess of the seasonal average.

The maximum number of days (92) since January this year was recorded in "moderate" category, followed by "very poor" (40).D14.  The levels of Particulate Matter (PM)10 and PM2.5 were recorded at 39 and 26 microgramme per cubic metre (ug/m3) respectively, which are well within the prescribed standards of air quality.New Delhi: For the first time this year, the national capital registered "good" air quality on Friday, owing to continuous rains in the city. Since June 1, when the monsoon season officially began, the capital has recorded 294.  Scientist Gufran Beig, project director, System of Air Quality and Weather Forecasting and Research, said that the air quality turned "good" because of continuous rainfall for two days in the city. The incessant showers since Thursday managed to wash away the pollutants in Delhi’s China Flow Control Valve Manufacturer air, giving the national capital its first "good" air quality day. It is a feat for a city that is used to witnessing high pollution levels, which are usually three to four times more than standards of pollution watchdogs.

The study published in the journal Environmental Science & Technology, highlighted that it is the plants and not technologies for cleaning the air near a number of industrial sites, roadways, power plants, commercial boilers and oil and gas drilling sites, that too in cheaper ways. They also considered the effect that restorative planting - bringing the vegetation cover of a given county to its county-average levels - might have on air pollution levels. And for the manufacturing industry - a broad sector - both ecosystems and technology could offer cost savings, depending on the type of factory.Washington: Planting trees around landscapes near factories and other pollution sources, is found to cut down air pollution by 27 per cent, a more viable and cheaper option than using technology.They found that adding trees or other plants could lower air pollution levels in both urban and rural areas, though the success rates varied depending on, among other factors, how much land was available to grow new plants and the current air quality..

There are win-win opportunities if we do - opportunities that are potentially cheaper and better environmentally," added Bakshi."The fact is that traditionally, especially as engineers, we dont think about nature; we just focus on putting technology into everything," said lead author Bhavik Bakshi, professor of chemical and biomolecular engineering at The Ohio State University."And so, one key finding is that we need to start pneumatic proportional valve looking at nature and learning from it and respecting it.To start understanding the effect that trees and other plants could have on air pollution, the researchers collected public data on air pollution and vegetation on a county-by-county basis across the lower 48 states.The analysis found that for one specific sector - industrial boilers - technology is cheaper at cleaning the air than ecosystem upgrades.Their calculations included the capacity of current vegetation - including trees, grasslands and shrublands - to mitigate air pollution. Then, they calculated what adding additional trees and plants might cost.In fact, researchers found that in 75 per cent of the counties analyzed, it was cheaper to use plants to mitigate air pollution than it was to add technological interventions - things like smokestack scrubbers - to the sources of pollution."

The thing that we are interested in is basically making sure that engineering contributes positively to sustainable development. Their research did not calculate the direct effects plants might have on ozone pollution, because, Bakshi said, the data on ozone emissions is lacking. And one big reason why engineering has not done that is because engineering has kept nature outside of its system boundary," Bakshi said. This figure varies by county and region - consider, for example, a county in the desert of Nevada and a county in the farmlands of Ohio.The analysis also didnt consider whether certain species of trees or plants would better "scrub" pollution from the air, though Bakshi said it is likely that the species of plant would make a difference in air quality.Researchers found that restoring vegetation reduced air pollution an average of 27 per cent across the counties.

The filter in the air purifier once saturated with the contaminants can be replaced with a new one to deliver high-grade performance.  The ionizer creates fresh air inside the room, which also elevates the mental well-being of the residents.The air purifier decontaminates the indoor air of harmful particles and toxic gases with a claimed success rate of 99. With the use of a timer, the device can be programmed China Flow Control Valve for sale to switch on or off at specific intervals thereby adding to the convenience of the user..9 per cent. The air purifier is priced at Rs 8,990 and is available at the Prana Air web stores. The device has a three-speed mode which can be operated using a remote.The device produces no noise, offering silent operation to the user while sleeping. The device has an in-built ionizer that cleanses the environment from the negative ions which are the potential source of any form of infection. The device can cleanse the air pollutants such as smoke, dust, negative ions, viruses including H1N1, bacteria, and PM 2. The device has a capacity of Clean Air Delivery Rates (CADR) of 334m3/h particulate matter and 200 m3/h formaldehyde that enables its service delivery. The air purifier delivers service in a room with an area of up to 41 square meters.5 particles.Prana Air has launched an indoor air purifier which curtails the perilous impact of air pollution stalking indoor living space such as homes and offices.
