Renovation of wastewater treatment system at An Phu Plaza Building – District 3
The project to renovate the wastewater treatment system at An Phu Plaza, carried out by NTS Engineering Co., Ltd, aims to upgrade the efficiency of domestic wastewater treatment and ensure the effluent quality meets current QCVN standards.
Through the survey and analysis of the current condition, NTS found that the system had shown signs of serious deterioration, with the actual treatment capacity reaching about 70% of the original design. This not only poses a risk of environmental pollution but also affects the operational efficiency and reputation of the building.
NTS is a consulting, design, and renovation unit that has proposed and implemented optimal technological solutions, ensuring that the system operates stably and safely after renovation, with the quality of the effluent meeting high standards.
Challenge
Renovating a wastewater treatment system in a continuously operating building requires:
- Flexible and precise solutions
- The treatment system is located in the basement, with limited space, low ceilings, and interspersed with many other engineering items. Therefore, the renovation plan must be carefully, and suitable for the actual conditions of the project
- Other building operations must continue to operate. This requires careful planning of the renovation process so as not to affect other building operations
- In addition, there are requirements for odor and noise control during implementation
Solution
The wastewater treatment system at An Phu Plaza applies AO technology combined with MBBR. NTS is required to improve the treatment efficiency without expanding the existing tank. The proposed renovation solutions include:
- Clean old wastewater treatment system
- Add suitable chemicals
- Add microorganisms in a reasonable ratio
- Apply deodorizing measures to the system
- Build soundproofing systems to meet project requirements
