Wastewater and sludge treatment

COWI provides consultancy services on the treatment and handling of municipal and industrial wastewater in Denmark and abroad.

Detailed knowledge of wastewater treatment processes, combined with automatic on-line control, improves the possibility to increase efficiency of treatment processes.

Today, wastewater treatment can be targeted directly towards the immediate composition of wastewater and the effluent criteria for different parameters.

Flexible solutions
We focus on providing flexible treatment solutions that can easily be adjusted for compliance with tightened effluent demands and sludge disposal regulations.

Sludge produced from the wastewater treatment represents both a problem and a resource. COWI has a long track record of successfully implemented projects on biogas generation and exploitation.

We focus on coherent solutions comprising economy, environmental considerations and HSE aspects.

Design and optimization

COWI has wide experience of assessment of capacities and operational optimization at existing wastewater treatment plants. Our services include dimensioning and design of new wastewater treatment plants as well as extension and up-grading of existing plants. We are among the leading consultants with regard to in-depth knowledge of the latest development in treatment technologies and advanced control systems.

We also focus on maximizing the hydraulic capacity of the treatment plants in order to minimize overflow in the sewerage system.
