In the wastewater treatment system, design is the first and most important step, deciding the stability of operation after being put into operation.

We always want to bring our customers advanced products and services with high efficiency but still save costs.

Therefore, the appropriate solutions, design and construction options are considered from the following factors:

• Pollution characteristics of wastewater sources;
• The current regulations apply to the output wastewater of enterprises or limit regulations on discharge into the receiving source;
• Conditions on area, geological and hydrological characteristics of the area where the wastewater treatment system is built;
• Cost of building wastewater treatment system;
• Satisfactory capacity of existing works, if any;
• The responsiveness of the equipment to the treatment works.

To be able to give a complete design drawing, we have to go through the following steps:

1. Building a scheme of wastewater treatment technology: The selection of an appropriate technology scheme depends on many factors such as characteristics of input wastewater, discharge volume, and requirements for output wastewater quality.
2. Establish design criteria: Design criteria are the basis for technology selection and the basis for data used in the process of calculating and designing wastewater treatment systems.
3. Substance balance calculation: To determine the effectiveness of the wastewater treatment plant and calculate the size of the work.
4. Hydraulic model building: The hydraulic model building is to know the appropriate pump locations, to ensure enough pressure for wastewater to flow through the construction site, to ensure that the treatment works are not flooded and not overloaded when the water flow occurs. waste generated with the largest volume.
5. Layout design: The layout of the premises is also very important in the design process. The layout of the premises must ensure that the path of the wastewater does not overlap, the location of the wastewater treatment system must be convenient for the collection of wastewater, and do not release gases into the environment affecting the environment. surrounding object.

Some design projects of wastewater treatment systems Southern Star Corp participated in the design include:

1. Hiep Phu centralized wastewater treatment station – District 9, Ho Chi Minh City
2. Dairy factory wastewater treatment station - Binh Dinh
3. Concentrated wastewater treatment plant at Acecook Vietnam factory
4. Centralized wastewater treatment station Phase 1 & 2 – Dong Nai
5. Wastewater treatment station of NaDa Brewery - Nam Dinh
6. Domestic wastewater treatment station Him Lam Residential Area – Binh Chanh District, HCMC
