2 ABSMaterials Products © ABSMaterials, Inc 2014 Advanced Materials to Treat Water Urban stormwater Micropollutants Agricultural: pesticides, nutrients Industrial waters Leachates Green infrastructure and low impact stormwater systems Waterway and watershed protection Ports Golf courses Airports Marinas, bilge Industrial and agricultural run-off

3 Osorb is a highly porous and flexible polysilsesquioxane. The network expands upon absorption of organic liquids and vapors. Absorbs: Solvents Lipids Pharmaceuticals Does not absorb water Swelling is due nanomechanical expansion of a mesoporous silica matrix. Osorb® Media © ABSMaterials, Inc 2014

4 Other features of Osorb media 1.Reactive metal particles (ex. Fe 0 ) can be incorporated into Osorb. 2.Osorb is biocompatible and resists biofilm formation. 3.Adsorption is reversible allow processes such as in situ bioregeneration. 4.NSF 61 certification currently in progress.

8 Drinking Water: Osorb ® -Metal Composites Al-OsorbFe-OsorbMg-OsorbNi-OsorbZn-Osorb -Metal-Osorb composites can be manufactured. Fe-Osorb preferred. - Examined reduction of motor oil, nitrate, phosphate, atrazine, estradiol, triclosan, and ethylene glycol. - Continue research to determine reduction mechanism and longevity. © ABSMaterials, Inc 2014

9 → 4.5 Acres Total Drainage → Footprint: 2,400 sq. ft. → 5,000,000 gallons rain/year → $105,000 → 12 Year Service Cycle → $0.0013/gallon cost Osorb Stormwater and LID Systems Low cost, highly effective way to treat stormwater in place. © ABSMaterials, Inc 2014

10 Osorb System - General Concept Design Osorb is mixed 0.2-1% in the soil near the rhizosphere layer to buffer contaminants. © ABSMaterials, Inc 2014

11 Why Osorb?: It is mixed in soil (1%) and absorbs toxins from stormwater inputs protecting plants and animals BioMix-Osorb is a blend of glass which when added to swales and filter strips will allow 30-90% improvements on nutrient controls.

13 Industrial Bioswale Design Pollutant Loads and Removal Efficiencies Measured at OARDC STAR Lab test facility. 10-27-12, >4 inches of rainfall this day from Superstorm Sandy. Bioswale design for 1.0-1.5 inch rainfall. 2012-14 NSF SBIR Funded Research © ABSMaterials, Inc 2014

14 Industrial Bioswale Design Pollutant Loads and Removal Efficiencies a Net mass removal (%) for each runoff event performed by integrating hourly flow rate and concentration data collected from influent and effluent. b Spiked solution consisted of nitrate (50 g N), phosphate (50 g P), atrazine (500 mg), 2,4-D (500 mg), Cu (20 g), Pb (20 g), and Zn (60 g) were added into the bioretention system during a rainfall event © ABSMaterials, Inc 2014

15 Water Saturated Zone BioMix-Osorb (0.5% w/w) soil (620,000sq. ft. in 0.5 ft. layer) Water Unsaturated Zone (225,000 sq. ft.) CLE010 – Osorb System for Deicer Runoff Treatment 1 inch rainfall = 1.65 million gallons of runoff PENDING Osorb Bioswales in Ohio: CLE Airport © ABSMaterials, Inc 2014
