Introduction
Water is a scarce resource, yet it is extensively used in industries and municipalities worldwide. Treating wastewater before releasing it back into the environment is crucial for companies and authorities.

Principle
The 3rd generation UNITANK® is a modern wastewater treatment system utilizing biological processes. It is implemented in various locations, such as the Brasilia municipality in Brazil and the Cam Ranh sugar refinery in Vietnam. The system focuses on the removal of suspended solids, phosphorus absorption, and the conversion of ammonia to nitrogen gas.

Applications
UNITANK® is suitable for both industrial and municipal wastewater treatment. It can function as a standalone installation or in combination with other configurations. It is particularly effective for organic wastewaters from industries like food, textile, chemical, petrochemical, and pharmaceutical.

Process Description
The UNITANK® BASIC configuration consists of a reactor divided into three compartments, each with an aeration system. The system operates in a cycle of two main phases and two short intermediate phases, without a separate sedimentation tank or sludge recirculation. The UNITANK® ADVANCED configuration includes additional compartments for advanced nitrogen and phosphorus removal.

Features
The UNITANK® system offers advanced treatment that meets strict effluent requirements. It is compact, odor and noise-free, fully automated, and energy-efficient. The modular design allows for easy integration and expansion, providing a favorable price/quality ratio.

Conclusion
UNITANK® systems are versatile and efficient solutions for a wide range of wastewater types, offering significant advantages in terms of design, operation, and cost-effectiveness.
