According to the data from the Ministry of Planning and Investment as of the end of March 2021, the country currently has 392 established industrial parks with a total natural land area of about 119.9 thousand hectares (out of the total 575 industrial parks in the development planning of industrial parks in Vietnam as approved by the Prime Minister).
Of 392 established industrial parks, 286 industrial parks have officially come into operation with a total natural land area of about 85.2 thousand hectares, an industrial land area of about 57.3 thousand hectares and 106 industrial parks are under basic construction process with a total natural land area of about 34.7 thousand hectares, industrial land area of about 18.2 thousand hectares.
Vietnam is emerging as a new industrial production center in Asia and receiving an increasingly large wave of FDI investment, so the number of investment projects in the field of infrastructure for industrial parks, industrial clusters is very vibrant. INDUSTRIAL URBAN ZONE development is emerging as one of the prominent trends in recent years. “Green Value“, “Sustainable Development” become KEY SELLING POINTS in the race of infrastructure investors to attract the customers, increase economic and service revenue, but not, any investor has enough financial potential to invest in GREEN infrastructure even though it clearly understands the value this benefit brings.
POPULAR INDUSTRIAL PARK, INDUSTRIAL CLUSTER WASTEWATER TREATMENT STATIONS IN VIETNAM
iIn Vietnam, most centralized wastewater treatment systems of industrial parks, industrial clusters use the following three technology groups:
|
CRITERIA |
TECHNOLOGY 1 |
TECHNOLOGY 2 |
TECHNOLOGY 3 |
|
Physicochemistry + A-O microbiological treatment |
Physicochemistry + SBR or ASRB |
Physicochemistry + microbiology + MBR |
|
|
Main steps in the technology diagram |
1. Collecting tank 2. Regulating tank 3. Flocculation reactor (PAC Polymer) 4. Physicochemical settling tank 5. Anoxic microbial tank 6. Aerobic microbial tank 7. Biological sedimentation tank 8. Disinfection and discharge compartment 9. Sludge tank |
1. Collecting tank 2. Regulating tank 3. Flocculation reactor (PAC Polymer) 4. Physicochemical settling tank 5. SBR batch microbial tank 6. Disinfection and discharge compartment 7. Sludge tank |
1. Collecting tank 2. Regulating tank 3. Flocculation reactor (PAC Polymer) 4. Physicochemical settling tank 5. Anoxic microbial tank 6. Aerobic microbial tank 7. MBR membrane tank 8. Disinfection and discharge compartment 9. Sludge tank |
|
Advantages |
– Simple design – Treat domestic TN effectively – Easy to adjust during operation |
– Smaller treatment tank volume than Technology 1 – Save construction area – Operating the phases in the treatment tank in batches is often fixed, with little space to adjust when necessary during operation |
– Water quality is often stable, better than Technology 1 & 2 thanks to MBR membrane steps – Save construction area |
|
Disadvantages |
– A-O microbial tanks often require a large area |
– When input TN or Ammonium fluctuates highly, treatment is often difficult to achieve. |
– Investment costs are often higher than Technology 1 & 2 |
NGO ACCOMPANIED WITH INFRASTRUCTURE INVESTORS
NGO does not aim to SELL AVAILABLE SOLUTIONS to the enterprises, instead, we wish to ACCOMPANY with the Investors, as BEST CONSULTING PARTNER ON COSTS for the Investors throughout the entire construction, development and maintenance process of industrial parks, industrial clusters
- Consulting on pollution treatment plans suitable for each stage of development of industrial parks, industrial clusters while still ensuring compliance with legal requirements
