This new edition has been published in a particularly critical background in terms of water problems: scarcity and quality degradation of water resources.

There is no doubt that much progress has been achieved in terms of international exchanges and of the publication of reference documents and this progress has laid the institutional, financial and technical foundations for resolving problems that exist throughout the world: in the South, the need to provide many populations with drinking water and to treat wastewater; in the North, taking stock of the new territorial schemes that are emerging, with towns that continue to extend, industrial and agricultural operations that are consuming more and more of this precious resource, discharges into the natural environment that durably contaminate waterways and aquifers.

More than ever, each has his role to play according to his field of expertise. Since , the men and women of SUEZ are specialist of the water treatment. These experts design, construct and operate drinking water production plants as well as reverse osmosis desalination units, plants used to remove pollution and reuse wastewater, and for treating sludge produced by the wastewater treatment system. Each edition of the Water Treatment Handbook has formalised this expertise, making it state-of-the art.

By providing all its readers with the technical means required to identify and understand the solutions offered, this work also promoted a true spirit of partnership between SUEZ and the actors in the system.

The previous Chapter 8 is now a special section: "Formulary and tools". For over ten years, needs, requirements, standards and, therefore, technologies, have moved on. Our readers will not fail to notice these changes in chapters regarding biological processes, separation by membranes, liquid sludge treatment, dewatered sludge treatment, drinking water treatment, treating municipal wastewater, treatment and conditionning of industrial water. We hope that you will find this Handbook a valuable tool that will always be by your side.

We also hope that it will help you share the passion the men and women of SUEZ feel for their discipline, and their pride in their work. Full actors in the resource revolution, they are wholeheartedly devoted to providing their clients with concrete, innovative and efficient solutions.

Water Treatment Handbook - Ondeo Degremont II

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.
