Wastewater Treatment System for Sao Dau Factory Area with Capacity of 500m3/day-night

1. Project Details:

• Executing Unit: Dai Nam Environmental Company Ltd.
• Treatment Capacity: 500 m³/day
• Effluent Quality: Treated wastewater meets the National Technical Regulation on Industrial Wastewater – QCVN 40:2011/BTNMT, column B, before being discharged into the receiving source.

2. Technologies Applied

• Screening Tank: Wastewater passes through a debris screen to remove large-sized particles, preventing pump blockages and pipe obstructions.
• Oil and Grease Separator: The separator consists of three chambers and operates on the principle of gravity to remove oils and fats from the wastewater.
• Equalization Tank: Designed with a sufficient retention time to equalize the flow and concentration of pollutants in the wastewater.
• Anoxic Tank: This tank facilitates the denitrification process, reducing nitrates in the wastewater.
• Aerobic Biological Treatment MBBR + Aerotank: Utilizes aerobic activated sludge on suspended media for biological treatment. Microorganisms adhere to the media and help process and separate sludge and wastewater.
• Sedimentation Tank: Performs the separation of biomass from the treated wastewater.
• Disinfection Tank: The disinfection tank holds treated water and uses disinfecting agents to eliminate harmful microorganisms.
• Sludge Storage Tank: This is where the sludge undergoes a degradation process.
• Odor Control System: Designed to collect and treat gases and odors emitted from the system, ensuring that no unpleasant smells affect the surrounding environment.

3. Technologies Applied in the Construction of the Wastewater Treatment System

• Advantages of the Wastewater Treatment System by Dai Nam Environmental Solutions Co., Ltd.
• Use of Common Anaerobic/Aerobic Treatment Technologies: These widely used technologies are easy to operate and ensure high-quality treated water.
• Application of Anaerobic/Aerobic Biological Processes: This process efficiently decomposes organic compounds and removes phosphorus from the sludge.
• Sludge Storage Tank: The tank is designed to store and reduce the solid content in the sludge.
• Cost-Effective Sludge Disposal: The system ensures reasonable costs for managing excess sludge.
• Flexible Operation Modes: The system can operate in automatic, semi-automatic, or manual modes, offering flexibility in management.
• Flexible Tank Layout: The system’s tank arrangement is designed for future capacity expansion, ensuring long-term adaptability.
• Optimized Tank Arrangement: The treatment tanks are organized to reduce construction costs and piping connections, maximizing efficiency.
• Optimized Gravity Flow Between Tanks: This feature saves energy and operational costs by utilizing gravity to transfer wastewater between tanks.
