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

Slide 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.

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.

Slide 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

Slide 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. Bio-Mix Osorb Enhanced Bioswale ABSMaterials, Inc 2014

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

Slide 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
