LOCAL CASE STUDY - Download

Hach tailor made online pollution monitoring

station to monitor wastewater discharge with

confidence for local regulatory, industrial

parks and companies

Vietnam

Who is the client?

Client in this case study would cover the regulatory sector, industrial parks and industrial company. This is due to a

regulation according to Vietnam’s 1994 Law on Environmental Protection (LEP) and Circular No. 08/2009/TT-

BTNMT (revised by Circular No. 48/2011/TT-BTNMT), that they have to install an automatic system for online

monitoring on their treated wastewater when exceed a certain limit.

What is the challenge?

Regulatory

Client pledges strict control of industrial wastewater discharges from industrial parks and industrial manufacturers

around the province, therefore the need for automatic monitoring system

Industrial Park

Client requires online monitoring system monitoring pH, COD, TSS as compulsory parameters. The parameters that

client would test for are pH, temperature, TSS, conductivity and COD

Industrial Company

Client has its system built at the sewage treatment station in the factory and with >1000m3/day, it requires online

monitoring system monitoring pH, COD, TSS as compulsory parameters.

What is the process and Hach’s solution to client?

Regulatory

The department pledges strict control of industrial wastewater discharged from 24 industrial parks and 40 largest

industrial manufacturers around the province.

• Department install automatic monitoring systems and cameras to observe discharge of industrial

wastewater

• Installation done at selective facilities: Vietnam-Singapore IP, Dong An, Viet Huong, Song Than, Song Than

and My Phuoc.

• System established according to Vietnam’s 1994 Law on Environmental Protection (LEP) and Circular No.

08/2009/TT-BTNMT (revised by Circular No. 48/2011/TT-BTNMT)

• Requires online monitoring of compulsory parameters like pH, COD, TSS, EC

• Depends on environmental impact assessment, environmental protection commitment of industrial zone

• Required to monitor more parameters such as EC, color, heavy metals, etc.,

• Data from online monitoring system is transferred to management station installed in Binh Duong to

detect and alarm when wastewater quality exceeds standardized level.

Hach’s total solution package for client is a Hach sc1000 controller and it is installed with 4 Hach sensors: Hach

pHD sc Sensor (testing pH and Temperature), Hach 3700 Inductive Conductivity Sensor (testing conductivity), Hach

Solitax sc Sensor (testing total suspended solids) and Hach UVAS sc Sensor (testing COD).

Industrial Park

The enterprise who manages industrial parks must install an automatic system for online monitoring their treated

wastewater according to Vietnam’s 1994 Law on Environmental Protection (LEP) and Circular No. 08/2009/TT-

BTNMT (revised by Circular No. 48/2011/TT-BTNMT).

Being the leading expert in quality, Hach is able to tailor make different total solution for clients of different

industrial park. In this case, we would see five different industrial parks with different requirements.

Client Case-study No. 1

It requires online monitoring pH, COD, TSS as compulsory parameters and one auto-sampler at in the system. Data

from online monitoring system is transferred to management station installed in Department of Natural Resources

and Environment of Dong Nai province to detect and alarm when wastewater quality exceeds standardized level.

Client has the online monitoring station installed in centralized effluent treatment plant of Nhon Trach III, Tam

Phuoc and Bau Xeo.

Hach’s total solution package for client is a Hach sc1000 controller and it is installed with 4 Hach sensors: Hach

pHD sc Sensor (testing pH and Temperature), Hach 3700 Inductive Conductivity Sensor (testing conductivity), Hach
