Features

Installation Area Large-Scale Excavation

For housing complexes, single tank systems can cater for up to 248 people. Large-scale installation area excavation is possible, meaning establishment costs can be reduced.

Stable Treatment Performance

Aeration processing is carried out following the separation of liquids and solids within wastewater, providing stable treatment performance. The system is compatible with a wide range of inflow water qualities, and can therefore be used for an array of building types.
