In the water 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 water 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 water treatment system is built;
• Cost of construction of water treatment system;
• The 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 water treatment technology diagram: The selection of an appropriate technology scheme depends on many factors such as input water characteristics, flow rate, and requirements for output water quality.
2. Establish design criteria: Design criteria are the basis of technology selection and the basis for data used in the process of calculating and designing water 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, and to ensure that the treatment works are not flooded and not overloaded when the water flow occurs. generated with the highest volume.
5. Layout design: The layout of the premises is also very important in the design process. The layout of the site must ensure that the path of the water does not overlap, the location of the treatment system must be convenient for collection, and does not emit gas into the environment, affecting the surrounding objects.

Some water treatment system design projects Southern Star Corp has participated in designing 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
