Detailed project description and legal basis

With strong technical capacity and equipment quality, for more than 6 years (2011, 2012, 2013, 2014, 2015, present), Viet An Enviro has been installing on 150 Automatic, continuous wastewater monitoring stations at High-Tech Parks, Industrial Parks and Industrial Complexes or factories with large discharge sources into the environment that meet the design and communication standards of the Department of Natural Resources and Environment of the provinces/Cities .

The installation of automatic and continuous wastewater monitoring stations is based on the following 4 legal bases:

  1. According Circular No. 08/2009/TT-BTNMT 15/07/2009 prescribed by the Minister of Natural Resources and Environment on regulations for management and environmental protection of economic zones, high-tech zones, industrial parks and industrial clusters.
  2. According to Circular No. 48/2011/TT-BTNMT ngày 28 tháng 12 năm 2011 of the Minister of Natural Resources and Environment regulating the amendment and supplementation of a number of articles of Circular No. 08/2009/TT-BTNMT dated January 15 07 of 2009 of the Minister of Natural Resources and Environment regulating the management and environmental protection of economic zones, high-tech zones, industrial parks and industrial clusters.
  3. According to Decree 38/2105/ND-CP dated April 24, 2015 of the Government regulating waste and scrap management.
  4. According to Circular 35/2015/TT-BTNMT dated June 30, 2015 of Minister of Natural Resources and Environment regulations on environmental protection of economic zones, industrial parks, export processing zones, and high-tech zones.

When going into the circulars and decrees, we can clearly see the regulations: All economic zones (EZs), high-tech zones (IPs), industrial zones (IPs) and industrial clusters (CCNs) and Factories located outside the Industrial Park that discharge waste directly into the Environment (with a discharge capacity of over 1,000 m3/day and night) must "Install an Automatic, Continuous Wastewater Monitoring System".

And even more clearly: "High-tech parks, industrial parks and industrial complexes must have centralized wastewater treatment plants. Centralized wastewater treatment plants can be divided into many units (modules) but must ensure that the entire amount of wastewater generated meets current environmental technical standards. Investors of centralized wastewater treatment plants must design and install an automatic, continuous monitoring system for wastewater flow, parameters: COD (Chemical Oxygen Demand), TSS (Total Quality). suspended solids), pH and some other typical parameters in wastewater (such as Color, Total Nitrogen, Total Phosphorus and Heavy Metals) of High-Tech Parks, Industrial Parks and Industrial Complexes according to the requirements of the Decision approving the report. environmental impact assessment report, before discharging into receiving sources. Automatic wastewater quality monitoring stations must ensure technical connection requirements to automatically and continuously transmit data to state environmental management agencies when requested by this agency. For existing automatic wastewater monitoring stations that do not meet the technical connection requirements for automatic and continuous data transmission, there must be an adjustment plan to meet this regulation.

Units in need (investors or wastewater treatment contractors) can also design, purchase equipment and install it themselves. “Automatic wastewater monitoring system, continuous It's also not too difficult. However, this is not easy, to make the system run stably and with low maintenance costs also requires what people often call "Know-How", because of the above analysis devices ( COD, TSS, pH, Color, TN, TP or Heavy Metals) are devices that combine Physics and Chemistry, so they need to be regularly "calibrated" to ensure the most accurate measurement results and also Needs a certain experience.
