4 P.4 DRINKING WATER GUARANTEE THE SANITARY QUALITY, CONTROL COSTS. SANITATION, ECONOMIC AND ENVIRONMENTAL ISSUES The hygienic quality of drinking water remains a fundamental concern throughout the world and is the subject of increasing media attention. Sanitary problems include bacteria control, as well as the need to limit the byproducts of treatment and the use of reactive agents. Consumers are also becoming more vocal about the organoleptic quality of their water (its taste and odor). In addition to this, with the current economic circumstances, municipalities are now closely examining each and every cost associated with the construction and operation of treatment facilities. Finally, with the rapid development of environmental issues, all of us are obligated to preserve the quality and the quantity of our natural resources. In certain regions of the world, the scarcity of water requires treatment solutions that demand a high level of efficiency and conservation. ADAPTED SOLUTION Supported by a global reputation for excellence and with over 70 years of experience, Degrémont is developing new solutions to these complex issues: from flotation to ultrafiltration, innovative technology that achieves for greater efficiency, automation and maximum reliability.

P.7 DRINKING WATER

8 P.8 DESALINATION PROVIDING ACCESS TO WATER FOR ALL, WHILE RESPECTING THE ENVIRONMENT. THE CHALLENGES OF SUSTAINABLE DEVELOPMENT 40% of the world s population suffers from a lack of fresh water, and this percentage will increase rapidly in the coming years. In large measure, the deficiency affects populations living in coastal areas. This is why desalination is proving to be an important solution. Desalination takes advantage of local resources rather than transporting water over longs distances. However, traditional desalination technologies can have some disadvantages. The development of this market is established, but the market is hindered by environmental and economic issues. To reduce the cost of desalination, we must lower the energy consumption as well as the operating expense of the reverse osmosis process. At the same time, to reduce the impact on the environment, we must develop solutions in renewable energy, lower the use of reactive agents and neutralize the impact of concentrated salt discharge on marine flora and fauna. ADAPTED TECHNOLOGICAL SOLUTIONS Degrémont is at the forefront of innovation providing clear solutions to solve the economic and environmental issues with desalination. Utilizing wind energy, recuperating energy, offering pre-treatment systems to limit the frequency of membrane washes, and improving processes for the disposal of concentrates are all ways Degrémont is innovating and optimizing the desalination offer.

12 P.12 REUSE FINDING ANSWERS NOW TO FUTURE CHALLENGES. RECYCLING: ONE FACET OF SUSTAINABLE DEVELOPMENT Today, preserving water resources is understood to be essential to solving human, environmental and economical needs. Water is vital to human life, yet close to two-thirds of the planet s population lacks sufficient resources. Water supplies are indispensable to preserving the planet s natural balance, but in recent years the warning signs have multiplied. even in temperate climates, shortages are regularly observed. By consequence, water has become an important economic issue. Still, water is a renewable resource. And in the same way that we are searching for means to reuse raw materials, we should be recycling water for use in agriculture (irrigation), industry and urban settings (supplying fountains, street cleaning, etc.). Reuse can help to avoid waste while preserving available resources, all at a lower cost. Progressively, numerous countries are putting regulations into place that offer a framework for developing reuse projects. RESPOND TO AND ANTICIPATE REAL NEEDS Degrémont is already at work innovating in reuse. The immediate objective is to respond to the needs of municipalities and industries in countries with water shortages while anticipating new expansion on regulations. Degrémont s innovative technological solutions are adapted to each situation, given that the required quality of water differs according to the use.

16 P.16 URBAN WASTEWATER ADVANCE DEVELOPMENT WHILE RESPECTING MAN AND THE ENVIRONMENT. CHALLENGES RELATED TO HUMANS AND EXPANSION Changing demographics, economic development, urban growth and population density increases all have the same consequence a progressive increase in urban wastewater volume. The challenge is compounded by the need to protect the environment and quality of life. Regulations on water quality are being strengthened to protect the environment. Consequently, guidelines for the treatment of urban wastewater have become much more stringent. This trend is further complicated by the difficult economic climate, creating the need to balance performance with cost controls. Public acceptance of urban wastewater treatment facilities is dependent on this equilibrium. FULFILLING COMPLEX AND DEMANDING SPECIFICATIONS Degrémont innovation in urban wastewater is seen in diversified solutions that can, for example, combine a biological treatment with clarification using membrane filters. Degrémont solutions also innovate through efficient designs with smaller footprints and lower consumption of energy and reactive agents.

22 P.22 BIOSOLIDS HARNESS THE POTENTIAL OF SLUDGE GENERATED BY WATER TREATMENT. ENERGY, ECONOMIC AND ENVIRONMENTAL CONCERNS Sludge volume is growing exponentially: the more water we treat, the more we produce. It is a global phenomenon, linked to demographic development, urbanism and economic activity. To meet the challenge, it is necessary to seek multiple solutions: finding a way to treat sludge while reducing volume, but also to obtain a safer, higher quality sludge. Evolving solutions in this field must integrate the economic reality that growing volumes raise treatment costs. However, the constraints represented by the increasing sludge volumes to be treated, can be offset by leveraging the enormous potential of biosolids. For example, the potential savings of utilizing biogas production is an important element for consideration in a treatment plants energy needs. OFFERING SAFE AND USEFUL SOLUTIONS TO IMPROVE PERFORMANCE In the biosolids field, Degrémont has positioned itself as a multi-sector player with an objective for innovation in treatment quality regardless of the final destination of the sludge.
