Introduction of Model Project for
Improvement of Water Environment inAsia

Scheme of the project
Promotion of Textile Dyeing Industrial Wastewater Treatment in Vietnam
Industrialization and environmental protection can coexist by applying appropriatetechnology and knowhow.
MOE Japan and we conducted treatment experimentation and factual investigation for
promotion of appropriate technology and for development of dyeing textile industry.

environment.
2) Applicable technology：
a: Biological Treatment
b: Physical‐Chemical Treatment
C: Advanced treatment (Ozone, Activated Carbon etc.)
3) Business Model
a: EPC modelb. Utility management business in the industrial park

Background of this project (1)1) Points of Vietnamese regulation
Compare to Japan or other developed country,regulation of Color and Cl is more strict.
In addition, regulation of COD and T‐N is also strict.
Main difficulties to treat waste water will be Color.

There’re 5000 textile companies approximately.
The trading amount is 8% of GDP (17bill$ Sales on 2012)
and ranked top of export amount (15.09bill$ on 2012, 13.2%)

Hanoi

Ho Chi Minh9Background of this project (2)3) Problema) There’re approx. 200 IP in Vietnam, however only around 25% of IP
have WWTP, or even they own, it is believed that wastewater is nottreated properly.
b) Primary treatment has not been managed properly.
c) The proper technology to treat color is not applied.

Seek the appropriate technology to treat
Textile Dyeing waste water in Vietnam

Conducted experimentation by pilot plant
Performance evaluation of each treatment process for various dyeing stuff-COD / Color reduction effect by biological treatment (MBBR etc.)
Chemical usage and optimization in coagulation sedimentation treatment(NaOCl, De-color agent, Flocculants, Polymer etc.)【MBBR】【Coagulation】

Process optimization and reduction of O&M cost-Studied process design for appropriate treatmentOptimized treatment for O&M cost reduction

Result of the project
KOBELCO studied the appropriate treatment process.
And it results in ……

Japanese dyeing factory in Vietnam‐ 2,000m3/day

After service‐24hrs O&M service‐ Biological treatment and Chemical treatment

Hong Kong textile factory in Vietnam

After service‐ 130m3/day‐ Biological treatment, Chemical treatment‐8hrs O&M service

and Activated Carbon

Last but not least

KOBELCO will keep promoting the treatment technology
for industrial waste water,
And contribute development of Asia
