A wide range of solutions to help you make the water transition in your region
Water treatment technologies and facilities play a central role in public health, providing access to quality drinking water, combating pollution, preserving the environment and biodiversity, and enhancing the resilience of communities. With the challenges posed by climate change and emerging pollutants, the water sector requires increasingly advanced and innovative solutions.
To address these challenges, Stereau develops and implements innovative processes tailored to various types of water and new sources of pollution. These processes are among the most effective and competitive in the market, and they contribute to:
- adapt processes to variations in water quality,
- effectively combat micropollutants,
- optimize energy and reagent consumption,
- preserve resources by regenerating them (reuse of treated wastewater and recycling of nutrients),
- agronomic and energy recovery from sewage sludge,
- reduce greenhouse gas emissions by limiting the use of fossil fuels.

Integrated solution for monitoring the saltwater wedge in coastal areas
In coastal areas, salt water can penetrate several kilometers inland following a drop in water level (drought or excessive pumping). If left unchecked, this phenomenon compromises a region's drinking water supply.
LANODOR®
Biological Treatment of Odors from Wastewater and Sludge Treatment.
Micropollutant treatment pilots
On drinking water and wastewater water treatment plants,span, Stereau Equipements et Services offers installation and monitoring of pilot treatment units for micropollutants (pesticides, drug residues, etc.).
