With decades of experience in the power industry, Veolia Water Solutions & Technologies is your key partner to develop and implement the most reliable water and wastewater treatment systems, providing an extensive range of technologies and services adapted to the power industry s requirements: Integrated health, safety and environmental protection Turnkey plants delivered with single-source responsibility to reduce risk Complete offering through equipment supply, maintenance and operating services Power industry experts working together with water treatment specialists A portfolio of over 250 technologies including specific solutions for the power industry Your concerns are our concerns Veolia Water Solutions & Technologies develops and engineers solutions for power generation clients by focusing on their key requirements: Reliability - avoiding costly downtime through proven technologies and local service Efficiency - developing solutions that help clients generate the maximum amount of electricity using the minimum amount of resources Environmental Compliance - engineering systems that ensure compliance with legislation while minimizing the plant s water footprint Dependability - delivering the project on time, avoiding additional costs

3 Proven technologies Power industry for the Actiflo The ACTIFLO process is an ideal solution for recycling valuable process water and providing pretreatment for boiler feed, product water and cooling tower make-up water to the power industry. ACTIFLO has also proven to be very efficient for treatment of cooling tower blowdown and wastewater applications such as pond level reduction or elimination, including algae removal. ACTIFLO /MULTIFLOTM Softening is a technological breakthrough in water treatment, offering some unique advantages over traditional clarification systems with the chemical precipitation of hardness, alkalinity, silica and other constituents (e.g., heavy metals). Demineralization units Systems utilize ultrafiltration, nanofiltration, reverse osmosis, electro-deionization, and/or ion exchange May include UV TOC destruction and membrane degas Achieve ppb levels of TOC, ppt levels of metals, and > 18 megaohms Discfilters The sturdy and compact California Title 22 approved Discfilter is a great choice for: Applications requiring space and backwash savings with large flows and fine filter openings down to 10 microns Clarification polishing (or primary and secondary clarification polishing) Cooling tower make-up and sidestream filtration Process water filtration Evaporation & Crystallization Zero Liquid Discharge (ZLD) systems Volume reduction, reuse/recycling of water Systems for fossil fuels as well as nuclear power OPUS Technology High water recovery and low waste volume RO-based system with effective scaling and fouling control Available with CeraMem or MULTIFLO pretreatment options Achieves Zero Liquid Discharge with the addition of a brine crystallizer Multiple Effect Distillation (MED) World leader in thermal desalination Condensate Polishing State-of-the-art technology

4 Understanding your treatment needs 1. Pretreatment For all types of feed water including sea water, groundwater, surface water and wastewater (recycling). Removal of suspended solids, colloids, organics, hardness, silica, iron and manganese from water 2. Boiler feed water treatment Processes and technological solutions to achieve low levels of TDS, TOC, silica and sodium Reduction of impurities entering the boiler system that cause reduced heat transfer, increased fuel consumption, steam contamination, carry-over, condensate corrosion, and turbine deposits, all of which can lead to a loss of production 3. Condensate polishing Removal of impurities from the condensed steam Reduction of suspended solids, iron and ionic impurities that lead to increased corrosion and downtime 4. Cooling tower water treatment Cooling tower sidestream Sidestream filtration and softening, water treatment chemicals and associated services to help power generation companies effectively manage their cooling towers. Reduce scaling and deposition, minimize microbial activity and more specifically, control legionella Cooling tower blowdown Technologies to treat or minimize blowdown water, in order to avoid corrosion and organic material in cooling towers due to excess concentration of contaminants. Minimize water use and wastewater discharge Calcium hardness reduction Silica and metals removal 5. Zero Liquid Discharge Evaporation & crystallization Cooling tower blowdown treatment Proprietary CoLDTM process for FGD blowdown and IGCC wastewater Radwaste Evaporators

5 Creating water solutions to meet your needs Veolia Water Solutions & Technologies designs, installs and commissions water and wastewater systems for Fossil Fuel, Nuclear and Solar Power Plants Recycling and reuse systems Treated municipal reclaim water can be reused in the plant, or wastewater from the power generation facility can be treated for reuse. We will help you: Meet environmental regulations Reduce plant discharge and consumption levels (water footprint) Reduce the burden and costs for local water treatment plants
