WASTEWATER TREATMENT Having built 2500 purification plants for urban wastewater, with sufficient capacity to serve populations of between 10,000 and 1,200,000 people, Degrémont possesses unique expertise in the control of pollution in water before it is returned to the environment. Not only does this task require the ability to ensure complete safety 24 hours a day, in compliance with the strictest of standards, but also great operational flexibility, so as to face up to variations in volume linked to the seasonal nature of consumption or extreme weather conditions.

In addition, in view of the requirements and the specific conditions that govern the installation of wastewater treatment plants in residential areas, it is obviously imperative that these facilities remain compact and that the pollution they produce is controlled. Lastly, Degrémont has demonstrated its ability to design and follow complex work scheduling, in order to guarantee uninterrupted service during modernisation work on old facilities.

In order to design plants that are suited to their customers' requirements, Degrémont's engineers have a wide range of processes at their disposal: physico-chemical purification, ozonization, suspended or attached growth, reuse and recycling, in particular through the use of the latest Ultrafor™ membrane technology.
