In the context of strong urbanization in the East of Ho Chi Minh City, modern real estate projects not only need to meet residential needs but also ensure sustainable and environmentally friendly development. The Saigon Binh An - The Global City Thu Duc project is a typical example of that trend, when the investor has focused on investing in a centralized wastewater treatment system at station 5 with a capacity of up to 1,600 m³/day. This is an important solution to ensure a healthy living environment for residents and strict compliance with regulations on urban environmental protection.

2. Wastewater Treatment System Overview
2.1 Collection and Coarse Screening Tank
Before entering the tanks, wastewater passes through a coarse screen rake to remove large debris (10–20mm in size), preventing pump clogging and pipe blockage. Sand in the influent settles at the tank bottom and is pumped to a sand drying yard. After sand removal, wastewater is pumped to the oil and grease separation tank.
2.2 Oil and Grease Separation Tank
Before entering, wastewater passes through a rotary drum fine screen to remove debris larger than 2mm. Domestic wastewater usually contains a certain amount of oil and grease, which must be removed to meet Column A standards of QCVN 14:2008/BTNMT. The separation tank is designed with two compartments, operating on a gravity principle where oil floats to the surface due to its lower density and is separated from the water. Wastewater then flows by gravity into the equalization tank. Waste oil and collected debris are periodically collected by authorized waste management units.
2.3 Equalization Tank
The equalization tank is designed to buffer variations in flow and pollutant concentrations. Submersible mixers installed at the bottom ensure even mixing to prevent anaerobic decomposition, thus limiting odor generation.
2.4 Anoxic Tank
In the anoxic tank, denitrification occurs, releasing nitrogen gas into the environment. Nitrate- and nitrite-rich wastewater is fed into the tank through a return flow from the biological tank, along with activated sludge to ensure adequate biomass for treatment.
2.5 Biological Tanks 1, 2, 3
The first biological tank applies an aerobic suspended growth process with carriers. Microorganisms adhere to the carriers and break down organic pollutants. Blowers supply oxygen via fine-bubble diffusers at the bottom of the tanks, promoting biological activity and decomposition of organic matter into simpler inorganic compounds.
2.6 Secondary Settling Tank
After biological treatment, the wastewater contains suspended activated sludge. The settling tank separates this sludge from the water by gravity. Water flows into a central inlet, disperses evenly, and suspended solids settle to the bottom, while clarified water flows over weirs into the intermediate tank.
2.7 Intermediate Tank
Clarified water flows by gravity into the intermediate tank, which buffers flow for subsequent filtration. Disinfection chemicals (chlorine-based compounds) are dosed into this tank to eliminate pathogenic microorganisms.
2.8 Sand Filter Tank
Water from the intermediate tank is pumped through a sand filter. During filtration, suspended solids are captured within the sand media. The filter undergoes backwashing to remove accumulated solids, which are returned to the equalization tank. The filtered water then proceeds to the fine filtration system.
2.9 Fine Filter Column
The fine filter column removes residual suspended solids larger than 5 microns. When the pressure differential across the filter reaches 2.5 bar, filter cartridges are replaced. Pressure is monitored using gauges installed before and after the filter. Water then flows to the UV sterilization system.
2.10 UV Sterilization System
The UV system completely eliminates bacteria before the treated water is discharged to the monitoring channel.
2.11 Effluent Monitoring Channel
Treated water meeting standards is directed to the monitoring channel. According to Circular No. 10/2021/TT-BTNMT, centralized treatment plants with a capacity greater than 1,000 m³/day discharging directly into the environment must have an automatic, continuous monitoring station. This monitoring station ensures consistent compliance with Column A standards of QCVN 14:2008/BTNMT.
Investing in a wastewater treatment system with a capacity of 1,600 m³/day at The Global City Thu Duc demonstrates the investor’s strong commitment to environmental protection, while enhancing the green infrastructure network for the entire area. This is also Station 5 in a series of wastewater treatment plants implemented by Dai Nam Environmental Solutions, marking a significant step in supporting real estate projects toward building sustainable, modern, and community-responsible living spaces.
