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

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 in Phuket, Thailand.

Cherng Talay OrBorTor Chief MaAnn Samran said that the 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 15 February, and will stay in use during a two-month trial until 15 April.

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” (SGD 17,154) for the two-month trial, Samran explained.

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

“This should help to remove the bad smell from the water,” said Samran. “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 black – that we are still trying to solve. We will hire a contractor to dig the black mud from the bottom soon.”

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.”
