History
Founded by Gilbert Degrémont in 1939 on the outskirts of Paris, the company soon entered the international market, with contracts in countries such as Egypt, Iran, Indonesia and Peru. In 1972, the company merged with SGEA to become Lyonnaise des Eaux, which later became part of the Suez Group. Today, it is a subsidiary of Suez Environnement and has operations worldwide. Gilbert Degrémont’s grandfather, Adalbert, had already set up a mechanical engineering plant in the North of France in 1870, which was converted by his son, Emile, into a rudimentary water treatment business. After completing an engineering degree in agronomics, Gilbert launched the Degrémont company that is still in existence today.
Drinking water
Degrémont is involved in the production of drinking water from groundwater or surface water in industrialized countries and the developing world. Its activities also include the desalination of seawater or brackish water for use as either drinking water or in irrigation. In all cases the water it produces is expected to meet the regulatory standards in operation in the relevant country.
Degrémont has 3,000 plants for the production of drinking water around the world, and 250 desalination [plants].
To produce drinking water, it uses a range of different technologies that include membrane ultrafiltration, ozone purification and ultraviolet disinfection systems. Its desalination plants notably use reverse osmosis technology.
Sewage and sludge treatment
The company is also involved in the treatment of sewage and sludge, which is a growing problem for urban areas in particular. It relies on a range of different technologies including physical, chemical or biological treatments, ozonization, membrane bioreactors, sand filters etc. Most wastewater is treated for use in irrigation or for use in industrial cooling systems. Degrémont has built 2,500 sewage treatment plants with the capacity to recycle 2.4 million cubic meters per day .
Sludge treatment is focused, first, on reducing the volumes of sludge produced and, second, processing it for reuse, mainly in agriculture. This is done through digestion, incineration, thickening, dewatering or drying, all of which can also lead to biogas recovery for use in energy production.
Activities
Degrémont estimates that 1 billion people are served by its 10,000 facilities around the world . These include 3,000 drinking water plants and 2,500 water treatment stations for urban wastewater. It carries out its activities using a number of different business models. • It designs, finances and builds facilities for the production of drinking water and for the treatment and recycling of sewage and sludge. This includes desalination plants that notably use reverse osmosis technology to create drinking water from seawater. • It can also operate those facilities for its customers in the public or private sector when contracted to do so. • Under its Build-Operate-Transfer contracts, Degrémont is responsible for financing and running facilities during the contract period (up to 25 years). Ownership is then transferred to the customer. • It sells equipment to facilities owned or run by third parties.
R&D
Degrémont spent €14 million to R&D in 2008 , and has filed over 500 patents since its creation. Recent investments have focused on improving the energy performance of plants and ultrafiltration membranes.
