How to treat domestic wastewater?

Environmental issues are increasingly concerned by investors and home buyers.

According to expert Dr. Truong Van Dan - Chairman of Green & Green Environment Joint Stock Company (MGB), a person who has successfully registered many patents on wastewater treatment, it is time for Hanoi city as well as the investors of residential projects. Like apartments, urban areas need to better apply science and technology to environmental management.

“Wastewater treatment is a very important issue, especially when the population density is increasing in big cities. Today, we need to pay more attention to sustainable design and especially the ability to reuse water,” said Mr. Dan.
Currently, some big cities have very strict regulations, requiring investors to build urban areas and apartments to pay attention to the problem of wastewater treatment, but cannot discharge it directly into the environment. formerly.

Da Nang is a typical city in terms of environmental requirements. When Mr. Dan's MGB company deployed the water treatment system for the FPT City project here, the treatment processes were built very closely.

The general director of the project, Mr. Bui Thien Canh, said that with the FPT City project, the investor does not apply the traditional treatment technology of a septic tank, because such storage turns less toxic substances into very toxic substances. , can only handle domestic waste, but cannot handle cleaning chemicals such as dishwashing liquid, soap.

"Instead, we introduced microbial wastewater treatment technology that can treat all types of waste from households, with the same cost as building a septic tank," Mr. Canh shared.
The outstanding advantage of this method is less organic sludge and toxic gas generation; It takes 10 to 20 years to vacuum once. All machinery and equipment applied in the water treatment process carry sustainable technology and can warn of a problem one year in advance. The life of the work is up to several hundred years, freeing labor and bringing high efficiency.

Mr. Dan also emphasized that treatment in a new direction is not only a matter of saving costs, costs, durability but also absolute assurance of water quality after treatment, which is a common trend of all cities. urban in the future.

FPT City is one of the pioneers in applying this new waste management system. The technology introduced by Mr. Dan has also been applied in major projects in Da Nang such as A La Carte Hotel Danang, Ba Na Hill, D'Capital Da Nang...

It can be seen that Da Nang is taking the lead in building green projects and green urban areas. For Hanoi, a strict city-wide wastewater management system will be essential in the context of an increasingly crowded population.
