The technology has succeeded in cleaning up 300 contaminated sites in Japan and has been introduced and tested in Laos, Indonesia, and Thailand. Bakture powder was used effectively at Hạnh Phúc Lake in Hai Phong last year. Mass fish deaths had occurred in lakes near Ha Long Bay, causing serious environmental pollution. Levels of dissolved oxygen, microorganisms, and ammonia were higher than accepted standards, due to unprocessed household wastewater being discharged into lakes and into to Ha Long Bay.

 

 

Bakture powder is made from natural materials such as pumice stone that help the environment clean itself by maximizing decomposition of contaminants and harmful substances by beneficial microorganisms present in the environment.

 

According to Pham Thi Huyen, who lives close to Hung Thang reservoir, said that recently the pollution level has significantly dropped, which is noticeable on hot, muggy days. Since the water was treated, fewer fish have died. Pollution has been decreasing recently.

 

Currently, 4 wastewater treatment stations in Ha Long City are capable of collecting and treating only 40% of the total sewage. The rest is directly discharged into lakes or into Ha Long Bay. The wastewater systems of many new residential areas haven’t yet been connected to treatment stations.

 

For the past two weeks, the engineers of the Japan-Vietnam Environment Improvement Company have tracked water treatment at Hung Thang equalizing reservoir using Bakture powder.
