Features

Efficient Installation for Large Housing Complexes

Single-tank systems can accommodate up to 248 residents, making them ideal for large-scale housing developments.
This allows for large-area excavation and installation, helping reduce overall construction costs.

Consistent, High-Quality Treatment Performance

Following the separation of solids and liquids in wastewater, aeration processing ensures stable and effective treatment.
The system is compatible with a wide range of influent water qualities, making it suitable for various building types and applications.
