The same that installed my aircons???
Surely hope not !!! All stopped working due to a shortcut...

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.

 

What exactly is a "wet scrubber" when it comes to dealing with PM2.5 pollution?

 

And of course, as numerous others above have pointed out, even if they actually work which is probably doubtful, their impact at 300,000 baht/$10,000 USD each is like trying to use an eyedropper to empty out the Pacific Ocean!

 

More amulets, propeller boats and firehose spraying from the gang who cannot shoot straight.

Wet Scrubbers are effective air pollution control devices for removing particles and/or gases from industrial exhaust streams. A Wet Scrubber operates by introducing the dirty gas stream with a scrubbing liquid – typically water. Particulate or gases are collected in the scrubbing liquid.

 

Apparently the technology works... in an industrial exhaust setting where everything is coming out of one or multiple pipes...

 

But guess what this kind of technology uses to be effective???  WATER!

They'd work as a way of improving industrial plant emissions. But not in trying to filter or improve the air in a mass city.

Enough wet scrubbers in Bangkok already.

Each device, costing Bt300,000 and built by Thai technicians, can effectively handle an area of about 50,000 square metres.

50,000 square meters equals 200 meter by 250 meter, or little less than 225 x 225 meters; some 16+ units are needed to clean one square kilometer.

 

According to Google Bangkok covers "1,569 km²", so it's more like 26,000 such units are needed, not four – which however are prototypes to test, and thereby a positive action – 26,000 x 300,000 baht equals an investment in the range of up around 8 billion baht, perhaps little cheaper for each unit when mass produced, plus ongoing maintenance and service...????

 

However, if it really works, then some 6-7 billion baht – plus maintenance and service – might be a good investment compared to the loss caused by air pollution; but stopping the cause for airpollution might be much cheaper and more effective...

all talk and no enforcement so what about the rest of Thailand they are hurting just the same as Bangkok. Just like the accidents on our highways no enforcement and on and on. 

Edith Clampton's advice for the 4 scrubbers is to send one to Patpong, Nana and Cowboy and the fourth to be kept in reserve for WHEN, not IF, there are breakdowns????

just turn a few tugboats upside down and let the propellers blow away the dust

I guess in the next photo of them we'll only see gray smog. Looks like the visibility was about 15m.

The over priced detectors that some one bought which turned out to be empty boxes with flashy lights that were worse at detecting than meer chance kind of springs to mind. 

Peeing into the wind could be more effective

Wet scrubbers eh?

 

Now in the UK that would refer to something rather different, although they could be found easily in Bangkok

and  they do  more  good, ranks  up there  with their  props  pushing water

too  intellectual you  really  need  this pair albeit twice the brains of this  bunch of geniarses.............ill throw  in "weed" for free

Next, make everyone stand outside for an hour breathing deeply-then spray molasses from the sky

Hopefully they will soon release the Royal Thai drone force to once again combat the air pollution scourge. The drones and air scrubbers bring to mind -- dumb and dumber.

I cant believe they dont crop dust bkk with molasses.  I hope these wet machines dont cause an uptick in moldy air.  Tell me how the water is going to be treated and tested.    Do no harm  comes to mind.  

Why no talk of adding  thousands  of low cost sensors.  Start negotiating with Cambodia and laos about serious burning  bans.    Maybe TAT can advertise free respiratory medical care for those that do have an issue. Until this air gets better I won't be planning another  vacation trip

"On average, they can absorb 150,000 cubic metres per day."

 

One cubic kilometre of Bangkok air is 1,000,000,000 cubic metres. Bangkok has an area of 1500 sq kilometres.

A drop in the ocean is a gross over estimation imho.

Strange how some organisations can over estimate figures and some can seriously under estimate others. ????????
