Vietnamese and Japanese experts gathered together at a seminar in the southern province of Dong Nai on October 15 to share their experiences in wastewater treatment techniques, especially in the plating industry and animal husbandry.

Dong Nai is home to 27 industrial parks, said Deputy Chairwoman of the provincial People’s Committee Phan Thi My Thanh, adding that as the locality has yet been able to fulfill its work in industrial sewage treatment, environmental pollution remains an implicit threat.

According to the local Department of Natural Resources and Environment, the number of businesses operating in the plating field is relatively high, discharging a negligible amount of wastewater but which contains a lot of metal pollutants that are difficult to fully treat.

Deputy Director of the Global Environment Fund Kazuhiro Oishi said both Vietnam and Japan have to face environmental issues such as polluted air, land, water as well as noise, especially in the development progress.

The process to treat sewage containing heavy metals requires hi-tech application, which costs a lot and takes time, Oishi stressed.

Some Japanese businesses operating in the environmental sector introduced their new cutting-edged technology in industrial wastewater and solid waste treatment.

They said they are willing to cooperate with local authorities and businesses to invest in the sewage treatment technology.-VNA
