Wastewater technology. Designed for operational reliability.

High-quality components and end-to-end engineering for reliable wastewater treatment and low OPEX

Systematic wastewater treatment for municipalities & industry

For more than three decades, we have planned and built municipal and industrial wastewater treatment plants designed for reliable, long-term operation. Our solutions range from mechanical pretreatment and biological treatment (activated sludge, MBR) to tertiary polishing and disinfection. As a full-service provider, we bring together engineering, mechanical and electrical plant construction, instrumentation, control and automation, commissioning and training, as well as maintenance, service and chemicals. Our focus is on reliable treatment plants featuring high-quality system components and clearly defined processes. This helps operators consistently meet discharge limits while keeping operating costs predictable.

Services across the entire plant lifecycle

We support you from the initial concept through to stable operation and select the right process for a comprehensive plant design. High-quality system components, clear documentation and well-defined process control ensure reliable plant operation and compliance with discharge limits. After handover, we’re here to help with maintenance, service and the right chemicals. This means fewer interfaces, reliable schedules, and costs and quality kept under control.
