2 ABSMaterials Products
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 © ABSMaterials, Inc 2014 * *

3 Osorb® Media 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. © ABSMaterials, Inc 2014

4 Other features of Osorb media
Reactive metal particles (ex. Fe0) can be incorporated into Osorb. Osorb is biocompatible and resists biofilm formation. Adsorption is reversible allow processes such as in situ bioregeneration. NSF 61 certification currently in progress. Internal and Third Party Testing Atrazine Internal/data shared with manufacturer Geosmin/MIB Water technology client in Korea Metaldehyde Internal and Thames Water in near future PAHs Internal and brownfield remediation client PCBs Internal and brownfield remediation client TCE Ohio EPA Estrogen mimics Internal and Scottish Water NP nutrients Internal and Ohio State University © ABSMaterials, Inc 2014

8 Drinking Water: Osorb®-Metal Composites
Al-Osorb Fe-Osorb Mg-Osorb Ni-Osorb Zn-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 Osorb Stormwater and LID Systems
Low cost, highly effective way to treat stormwater in place. → 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 © 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 Bio-Mix Osorb® Enhanced Bioswale
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. © ABSMaterials, Inc 2014 * *

13 Industrial Bioswale Design
Pollutant Loads and Removal Efficiencies NSF SBIR Funded Research Measured at OARDC STAR Lab test facility. , >4 inches of rainfall this day from Superstorm Sandy. Bioswale design for inch rainfall. © 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
