PROJECT-SPECIFIC SOLUTIONS
Engineered Around Your Project.
AAA adapts each domestic wastewater treatment solution to the specific conditions and requirements of the project. Site conditions, climate, available space and treatment targets are considered from the engineering stage onward. Where appropriate, systems can also be implemented in a containerized configuration, while additional treatment stages can be integrated where treated water is intended for reuse.

CONTAINERIZED SOLUTIONS
Compact. Pre-Assembled. Easy to Install.
Treatment technology and technical equipment are integrated and pre-assembled within the container – reducing on-site construction and installation work for faster, easier and more cost-efficient project implementation.
PRE-ASSEMBLED · EASY TO INSTALL · REDUCED ON-SITE WORK

WATER REUSE
Treatment Tailored to the Intended Reuse.
Where water reuse is required, additional treatment stages can be integrated according to the intended application and required water quality – turning treated wastewater into a valuable resource.
APPLICATION-SPECIFIC · RESOURCE EFFICIENCY
KLARO SYSTEM EXTENSIONS
