EGAT launches air purification tower to overcome PM2.5
Electricity Generating Authority of Thailand (EGAT) unveils the prototype of air purification tower to deal with PM2.5 air pollution on Wednesday.
Due to severe PM2.5 in Thailand, the development of air purification tower for using in communities came after cooperation between EGAT researchers and inventors, said EGAT governor Boonyanit Wongrukmit.
"The machine can capture more than 80% of PM2.5 and purify up to 30,000 cubic metres per hour, covering area within 250 metres," he said.
He said air purification towers were initially installed in EGAT areas, so the agency can improve their efficiency further.
He added that machines would be installed in other areas in the future, especially Northern Thailand where the situation is worrisome.
This innovation, which is six metres high and has six tonnes of weight, employs plasma generation techniques which generates electric charge to capture PM2.5, according to Boonyanit
"Moreover, the knowledge from this research can applied to dust filter efficiency measurement of other protective devices like facemasks and air purifiers at home," he added.
PM2.5 is fine dust less than 2.5 micrometres in diameter. It can be fatal. Long-term exposure damages respiratory systems and blood vessels.
