The Rajaprajanugroh Foundation Under Royal Patronage has provided four wet scrubber prototypes to deal with PM2.5 airborne dust particles for installation in highly polluted areas, Pollution Control Department director-general Pralong Dumrongthai said.
The Bangkok Metropolitan Administration will be responsible for locating and maintaining the devices.
Pralong said four areas with high dust values are Din Daeng, near Vibhavadi Forest Park Road, an area with heavy traffic; the Victory Monument area, where two prototypes could be used as there are hospitals and heavy traffic; and Lumpini Park, where people exercise.
The wet scrubber prototypes can absorb two cubic metres of air per second, or 172,000 cubic metres per day. On average, they can absorb 150,000 cubic metres per day. Each device, costing Bt300,000 and built by Thai technicians, can effectively handle an area of about 50,000 square metres. The know-how will be distributed to the public, so more of the machines can be built to tackle PM2.5 dust pollution.
