Today, it is a subsidiary of Suez Environment [1] [2] and has operations worldwide. 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. To produce drinking water, it uses a range of different technologies such as settling, flottation, media filters, membrane ultrafiltration , ozone purification or ultraviolet disinfection systems. Its desalination plants use the reverse osmosis technology.

Today, it is a subsidiary of Suez Environment [1] [2] and has operations worldwide. 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. To produce drinking water, it uses a range of different technologies such as settling, flottation, media filters, membrane ultrafiltration , ozone purification or ultraviolet disinfection systems.

Its desalination plants use the reverse osmosis technology. Sewage and sludge treatment[ edit ] 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.

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. These include 3, drinking water plants and 2, 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.

Ownership is then transferred to the customer. It sells equipment to facilities owned or run by third parties. There have been 10 French editions and 7 English editions Lavoisier , and it has been published in 10 languages in total. Recent investments have focused on improving the energy performance of plants and ultrafiltration membranes.
