1 NEXT GENERATION DOWEX MARATHON ION EXCHANGE RESINS FOR INDUSTRIAL WATER TREATMENT Small change, big impact.

2 Next Generation DOWEX MARATHON Ion Exchange Resins For Industrial Water Treatment The best of two trusted technologies. The new DOWEX MARATHON line of Ion Exchange Resins combines the best of DOWEX MARATHON and AMBERJET technologies, re-engineered to meet the challenges of industrial water treatment today. This means that DOWEX MARATHON IX resins enhanced capacity and ideal balance of properties enable operators to experience maximum usable capacity with minimum use of chemicals and rinse water all with the physical stability and performance that DOWEX MARATHON and AMBERJET users have relied on for almost three decades. Next generation DOWEX MARATHON IX resins offer: Higher regenerability and operating capacity Benefit from longer cycles, less waste, higher net yield and lower operating costs in existing plants Use smaller vessels and footprint for the required output with new plants and equipment Higher osmotic and mechanical stability Longer resin life and lower replacement cost Less swelling Hold more resins in vessels, for fewer regenerations in existing plants Use less cylindrical height with new equipment and plants Flexibility Utilize in all system designs, including AMBERPACK Packed Beds, UPCORE Layered Beds, water hold-down counter-current, co-current, and mixed beds Streamline and simplify your inventory 3

3 Up to 10% more productivity. Want to make a big impact on water efficiency? Think small. Really small. With Dow ion exchange (IX) technologies, decisions on a molecular level can deliver outsized benefits. While IX resin typically represents a very small percentage of your operating expenditures, optimizing IX technology can lower your demineralization costs and wastewater volume significantly. In fact, with the next generation of DOWEX MARATHON Ion Exchange Resins, combined with optimized system design and utilization, you can achieve as much as 10% greater productivity from your raw water. * These resins have been re-engineered specifically for efficiency in industrial water treatment increasing throughput while decreasing regenerations and chemical use. So you get more demineralized water with less waste. Even better over time. With water scarcity and costs having an increasing impact on your bottom line, now more than ever it makes sense to take the long view when it comes to controlling costs. With the increase in productivity DOWEX MARATHON IX resins deliver day after day, the savings can really add up while your total cost of ownership can go down.

4 Reduce regenerations, chemical use and waste. The efficient performance of DOWEX MARATHON Ion Exchange Resins helps lower your operating expenses by reducing the need for costly, time-consuming regenerations, as well as chemical use and waste. Plus the flexibility of these resins facilitates system design improvements that increase water efficiency. Packed bed systems such as AMBERPACK and UPCORE Reverse Flow Ion Exchange Systems minimize dead space and unwanted dilution. Layered bed systems using weak electrolyte resins improve efficiency up to 30%.
