Industrial wastewater treatment has become one of the significant challenges for businesses and environmental management authorities. To ensure wastewater is treated to the required standards, designing industrial wastewater treatment technologies is essential. Đại Nam Environmental Solutions will provide the latest diagrams in this article.

1. Where Does Industrial Wastewater Come From?

According to the regulations issued in QCVN 40:2011/BTNMT, wastewater from production or service processes must adhere to specific regulations. Currently, the following industries need to comply with regulations related to environmental discharge:

Paint manufacturing plants
Car wash services
Iron and steel processing plants
Multi-industry industrial zones
Food processing plants
Textile dyeing mills
Electroplating and galvanizing plants
Concrete mixing plants
Paper recycling plants
Acidic chemical production plants.

2. The Most Advanced Industrial Wastewater Treatment Technologies

With the diversity of industries and services, different types of industrial wastewater are generated with varying components. Therefore, appropriate treatment processes are needed to ensure the safety of the wastewater before being discharged into the environment. Below are some of the most commonly used industrial wastewater treatment technologies.

2.1 SBR Technology

The SBR (Sequencing Batch Reactor) technology for industrial wastewater treatment offers high treatment efficiency with moderate installation and operation costs, suitable for small to medium-scale systems. The system’s structure and equipment are durable, designed for long-term use. The SBR system is easy to install and can be expanded easily. Additionally, SBR can effectively remove harmful substances such as nitrogen from high-volume wastewater.

2.2 MBBR Technology

The MBBR (Moving Bed Biofilm Reactor) technology provides outstanding performance, reducing BOD (Biochemical Oxygen Demand) values by up to over 90%. This not only ensures that the treated water meets standards but also contributes to more effective environmental protection.
A notable advantage of MBBR technology is its space-saving capability, with construction area reduced by 30% to 40% compared to other systems. Consequently, construction and labor costs are also significantly reduced, offering economic benefits to investors.
The compact size of MBBR’s materials and equipment makes installation and operation straightforward. Moreover, MBBR technology is energy-efficient, reducing operational costs. It effectively treats wastewater with high concentrations of organic chemicals by using biofilm carriers instead of traditional activated sludge methods. This opens up opportunities for use in various industrial sectors where wastewater has complex characteristics and requires high-level treatment.

2.3 UASB Technology

The UASB (Upflow Anaerobic Sludge Blanket) system can reduce BOD by up to 80%, ensuring that the treated wastewater meets safety standards before discharge. UASB technology has the advantage of low energy consumption during operation, resulting in significant cost reduction and contributing to lower carbon emissions, making it more environmentally friendly.
UASB technology is widely applied in systems with medium to high COD (Chemical Oxygen Demand) concentrations, particularly in industries such as seafood processing, starch production, and textile dyeing. The method meets strict treatment requirements, ensuring that the treated water quality complies with national environmental regulations.
