1 WATER SOLUTIONS WITH KYNAR PVDF WATER FILTRATION FOCUS

2 NEARLY 1 BILLION PEOPLE DO NOT HAVE ACCESS TO CLEAN DRINKING WATER Our world depends on water. The fact that over 10% of the population does not have access to clean water creates a huge need for innovative solutions in the water filtration market. The success of these developments is highly dependent on material innovations. The world is becoming more extreme

3 MARKET OVERVIEW BENEFITS SOLUTIONS 3 WATER MARKET PRESENTATION

4 DRIVERS IN THE MARKET URBANIZATION PLANT FOOTPRINT SEVERE CHEMICALS CLEAN WATER Poor quality of ground/surface water Scarcity of freshwater Plants are required to operate beyond their design capacity/capabilities Cl ClO 2, NaOCl, and Chloramines Much more extreme oxidization 4 WATER MARKET PRESENTATION

5 A VARIETY OF END APPLICATIONS Showers to Flowers 10% reintegration with potable water 5 WATER MARKET PRESENTATION

6 PROBLEMATIC CYCLE IN AGRICULTURE WATER Re-use of polluted water More pollutants added each cycle Potential for pollutants reaching our food Ultra-Filtration can be used here 6 WATER MARKET PRESENTATION

7 CLASSIFICATIONS OF MEMBRANES Pore Size Filtration Pressure Macroparticles >10µM Sand filtration = < 10psi Turbidity Algae Giardia Cryptosporidium Bacteria 0.1-1µM µM 1-10nm nm Microfiltration (MF) = 10-30psi Organic Asbestos Macromolecules Virus Ultrafiltration (UF) = 15-35psi Organic Hardness Radionuclides Chemicals Color Nanofiltration (NF) = psi Metal Ions Salt Electrodialysis Reversal (EDR) = psi Brackish Reverse Osmosis (BRO) = psi Seawater Reverse Osmosis (SWRO) = psi 7 WATER MARKET PRESENTATION

8 WHY DO WE NEED MF & UF? Macroparticles Sand filtration = < 10psi Turbidity Algae Giardia Cryptosporidium Bacteria Microfiltration (MF) = 10-30psi Organic Macromolecules Asbestos Virus Ultrafiltration (UF) = 15-35psi Sand filtration usually starts with safe water There is wide variability in how safe the safe water really is Sand filtration CANNOT remove potentially harmful bacteria and viruses 8 WATER MARKET PRESENTATION
