Officials turn to ozone to help clear Bang Tao canal wastewater stench

PHUKET: Cherng Talay Tambon Administration Organisation (OrBorTor) has installed an ozone water-treatment machine along the Bang Tao Canal to help treat the dirty water there, which has turned black with pollution and is causing a foul stench along its course to the southern end of Bang Tao Beach.

Cherng Talay OrBorTor Chief MaAnn Samran said that an urgent – albeit temporary – solution was needed along the canal while waiting for the full wastewater-treatment facility to come onstream.

The ozone generator was installed on Feb 15, Mr MaAnn told The Phuket News today (Feb 26).

“It will stay in use until at April 15 during a two-month trial. If it proves successful, we will keep it in place,” he said.

The ozone water-treatment machine, installed near the end of the canal just before the stream empties across the beach, is costing the Cherng Talay OrBorTor “about B400,000” for the two-month trial, Mr MaAnn explained.

Hopes are high that the small facility will have the desired effect.


“This should help to remove the bad smell from the water,” Mr MaAnn said.

“For now, the surface of the water is clear and when the machine is in operation there is no smell, but the bottom of the canal is back – that is we are still trying to solve,” he added.

“We will hire a contractor to dig the black mud from the bottom soon,” he said.

Mr MaAnn said that most businesses in the area were run by socially responsible people who did not release untreated wastewater into the canal.

However, he admitted, “Some places and villages do not cooperate. They still quietly release untreated wastewater.”

"And why not attack some places and villages that not cooperate?" Good idea.Maybe they could use those "Oplot T 84"tanks the military ordered from the Ukraine for the attack ! Take no prisoners !

PN article Oct. 5 2018, it was revealed that the Cherng Talay O Bor Tor was given a budget of 300 million baht to build a system to treat this 'black water' before it could enter the sea. Ma Ann was quoted in that article that he would have a resolution to the problem within 2 months. Where is this 300 million baht "prototype" sewage treatment system? Don't cry over 400,000.

“Some places and villages do not cooperate. They still quietly release untreated wastewater.”

And yet, after years of this, they've decided not to do anything about it.

Here we go again...look, look, we are doing something, even though it is not suitable for this task.

Look forward for a comment of a scientist, a chemist to tell us or this trick is working.
Perhaps for the smell, but how about water quality?
And why not 'attack' some(?) places and villages that not cooperate? Do they pay for their polluting?

Mr Samran ought to take a look at the certain car rental facility named after the ocean it discharges it's filthy oily wastewater into.  No time to treat just goes straight to the very south end of BangTao Bay. While he's in town, he should check all the blue lines lining the canal that runs through the main part of the bridge.  Dirty water drains into it all day
