1 FOSSIL POWER PLANT WATER TREATMENT Generating optimal performance, powered by Dow.

2 Fossil Power Plant Water Treatment Meet rising demand, and tougher challenges. For more than 70 years, innovative technologies from Dow have purified the water that drives the turbines in generators producing the power communities need worldwide. Today, as challenges in generating power are growing right along with the demand, Dow is still here to help improve your plant s productivity, protect valuable assets, and maintain consistent, uninterrupted operation. With world-class quality and innovation in water treatment technologies, along with local expertise and global experience, we can make a difference in your power plant and the communities you serve. We work closely with utilities, service providers and equipment manufacturers to provide integrated solutions in applications that include: Make-up Water Treatment System Condensate Polishing Plant Stator Cooling Water Cooling Water Make-up Cooling Tower Blowdown Flue Gas Desulfurization (FGD) Minimum Liquid Discharge (MLD) Ash Pond Clean-up 2

3 Technologies that treat water better. Fossil Power Plant Water Treatment Ultrafiltration Ultrafiltration (UF) reduces colloids, particles and bacteria in a continuous system, helping to deliver higher reliability and lower maintenance with a smaller system footprint. An excellent choice as a pretreatment for downstream units like reverse osmosis (RO), UF helps to reduce the impact of poor or variable make-up water on boiler and cooling system management. Recommended Products DOW IntegraFlux SFP-2880XP Module DOW Ultrafiltration SFP-2880 Module DOW IntegraPac IP-77XP Skid DOW IntegraPac IP-77 Skid Reverse Osmosis & Nanofiltration RO and nanofiltration (NF), using sustainable Dow technologies, offer an excellent balance between efficient contaminant removal, demineralization, reliability and cost-effectiveness. Dow s elements remove a broad range of molecules and ions helping to minimize scaling, fouling-causing components and ions from the steam cycle; increase the number of cooling tower cycles; and facilitate the use of alternative water sources to address water scarcity challenges. Recommended Products DOW FILMTEC brackish and seawater elements, especially: DOW FILMTEC ECO Elements DOW FILMTEC FORTILIFE Elements Ion Exchange Ion exchange (IX) resins efficiently remove ionic impurities, producing softened, partially or fully demineralized water, up to ultrapure water quality. IX resins can be highly specialized to remove a narrow or wide range of contaminants. Dow s resins, trusted in plants worldwide, are tailored for specific fossil power applications, from softening to make-up water demineralization and polishing, condensate polishing, and flue gas desulfurization.

5 1 MAKE-UP WATER TREATMENT SYSTEM Reduce corrosion, scale, fouling and other asset-limiting concerns for your boiler and cooling tower. Protect equipment with design configuration options using one of the widest ranges of products for pretreatment, demineralization and polishing make-up water. Find Dow UF, RO, and IX solutions that help address your water source, condition and availability needs.. 2 CONDENSATE POLISHING PLANT Improve plant reliability and protect critical components, such as boilers, steam generators and turbines. Remove dissolved impurities such as chloride, sulfate silica and sodium, along with particulate iron and copper corrosion products. Benefit from world-class IX technologies, in deep bed or powdered resin beds, as the backbone of the condensate polishing system. 3 STATOR COOLING WATER TREATMENT Prevent corrosion of stator bars to help prevent failure of the generator. Use a mixed bed polisher to remove soluble contaminants. FLUE GAS DESULFURIZATION (FGD) & ASH POND CLEAN-UP Meet regulatory requirements with effective treatment of FGD blowdown water prior to discharge. Remove trace contaminants and meet discharge requirements with solutions that include UF and RO membrane pretreatment, and highly selective IX resins. 5 MINIMUM LIQUID DISCHARGE (MLD) & REUSE Recover and return up to 90% of cooling tower blowdown water for make-up. Reduce water usage and costs, comply with regulations more cost-effectively. Realize efficiencies with solutions combining UF, RO and NF. Achieve high recovery at lower cost with MLD than with Zero Liquid Discharge. 6 COOLING TOWER BLOWDOWN Recover and return up to 90% of blowdown water for make-up. Reduce water usage and costs, while complying with regulations more cost-effectively. Combine UF, RO, and NF for solutions tailored to help address your needs. DID YOU KNOW? Checking condensate polishing anion resin kinetics can help confirm that the resin will provide protection during a condenser leak. 5
