2 Topics SIBROM Installations System Overview Bio-filtration Reverse Osmosis Why SIBROM is best available technology (BAT) Superior water quality metrics The advantages of Biologically stable water Economics

3 SIBROM Systems in First Nations Communities 10 full scale SIBROM WTPs in operation 3 under construction 2 scheduled for construction in early ) Yellow Quill First Nation 2) Pasqua First Nation 3) George Gordon First Nation 4) Whitecap Dakota First Nation 5) Dakota Dunes Casino 6) Saddle Lake Cree Nation 7) Poundmaker 8) Muskeg Lake Cree Nation 9) Kawacatoose 10) Witchikan Lake 11) Saulteaux 12) James Smith 13) Moosomin 14) Makwa Sahgaiehcan First Nation 15) Shoal Lake Cree Nation

4 SIBROM = Sapphire Integrated Biological Reverse Osmosis Membrane Three core processes; 1) Biological Filtration 2) Reverse Osmosis Membrane Filtration 3) ph adjustment

5 SIBROM = Sapphire Integrated Biological Reverse Osmosis Membrane Bio-filtration Employs indigenous micro-organisms & natural metabolic processes to purify water Conditions conducive to the growth of specific bacterial populations are maintained within bio-filters. Biological filtration processes occur at a rate 10,000 times greater than in nature Contaminants removed biologically are either nutrients or energy sources for the bacterial populations Some contaminants are consumed or remain within the biomass i.e., Fe 2+,, NH4 + Others are transformed into compounds ideally suited to removal by the RO membranes i.e, Mn 2+ to Mn 3+ As 3+ to As 5+ Downstream heterotrophic plate count in treated water is < 2/ml Canadian guideline is < 500/ml

6 SIBROM Contaminant Removal Summary Bio-filters Iron Arsenic Ammonium Phosphorus Bioavailable DOC Turbidity Sulphide Methane RO Membranes Manganese & any remaining ammonium and arsenic ions Dissolved Organic Carbon Any remaining particles Dissolved solids: Calcium Magnesium Sulphates nitrates

7 SIBROM = Sapphire Integrated Biological Reverse Osmosis Membrane Ceramic Filtration Material FILTRALITE Filtration material within the bio-reactors looks like coffee grounds Branded Filtralite, this media provides 5 Star Hotel Rooms for bio-film forming bacteria By providing the right conditions, iron bacteria will remove iron, nitrifying bacteria will oxidize ammonium etc. Bacteria Attached to filtration material

8 Why SIBROM is The Best Available Technology 1) Superior water quality by any water quality standard 2) Biologically Stable Water 3) Non-Corrosive inorganically stable water 4) DOC removal below detection limits 5) Reduced dissolved gases removed 6) Favorable economics

9 Typical SIBROM Water Quality Results Highlighted compounds represent bacterial nutrients or energy sources treated in the Bio-filters Parameter Guideline value Yellow Quill Yellow Quil Raw Water Tap Water Alkalinity (mg/l) <500 (SK) Aluminum (mg/l) <0.1 (operational) <0.005 <0.005 Ammonium-N (mg/l) <5 (EU) 4.7 <0.05 Arsenic (mg/l) < <0.002 Barium Boron (mg/l) < Calcium (mg/l) <100 (EU) Chloride (mg/l) < Free Chlorine (mg/l) >0.20 >0.30 Copper (mg/l) < Dissolved Organic Carbon (mg/l) <5 (SDWF) 11 <0.5 Fluoride (mg/l) < <0.05 Iron (mg/l) <0.3 (AO) Hardness (mg/l) <800 (SK) Heterotrophic Plate Count (HPC) <500 ct/ml <2 Lead (mg/l) <0.01 <0.002 <0.002 Magnesium (mg/l) < Manganese (mg/l) <0.05 (AO) Nitrate-N (mg/l) <10 < ph Phosphate (mg/l) No guideline 0.23 <0.01 Redox (ORP) (mv) No guideline < Selenium (mg/l) <0.01 <0.005 <0.005 Silicon (mg/l) No guideline Sodium (mg/l0 <200 (SK <300) (AO) Strontium (mg/l) No guideline Sulphate (mg/l) <500 (AO) Temperature ( C) <15 (AO) <6 <10 Total dissolved solids (mg/l) <500 (SK <1,500) (AO) Turbidity (for raw water, turbidity after aeration) < <0.005 Zinc (mg/l) <5 <0.005 <0.005

10 All microbial nutrients and energy sources are removed from SIBROM treated water Prevents downstream bio-fouling in: RO membranes Reservoirs Distribution systems Biologically Stable Water

11 Best Available Technology Non-Corrosive inorganically stable water RO treatment yields water with a <ph 6 which is highly corrosive Corrosive water can leach out copper and lead from distribution pipes Re-adjustment of the ph is accomplished in a proprietary SIBROM mineral contactor employing calcium & magnesium carbonate salts DOC removal below detection limits DOC reacts with chlorine and forms disinfection by-products many of which are carcinogenic i.e.trihalomethanes Removal of dissolved organics improves the effectiveness of chlorination Typically Cl usage with SIBROM treated water is reduced by 90% Reduced dissolved gases removed Methane Hydrogen Sulphide Environmentally sustainable process Employs indigenous mico-organisms No pretreatment chemicals required RO concentrate is environmentally benign

12 Economic Benefits Lower chemical costs Lower Cl dosages Low antiscalent required Reduced Backwashing 95% reduction in water used Reduced reservoir cleaning Coin test Extended membrane life Reduced membrane replacement Eliminates cleaning costs Reduced labour costs Backwashing Minimal operator interventions Continuous process Remote monitoring and intervention control systems Designed and manufactured by SWI

13 Conclusion SIBROM = BAT Conforms to the most rigorous water quality standards in the world Proven Technology 15 Full Scale WTPs in operation by the end of 2013 Proven Economics Reliable Manufacturer Financially stable Solid track record
