Cetco Combines Municipal WWT and BioSolids Treatment • Municipal Waste Water and the Sludge contain hazardous and foreign substances leading to: • Complex and costly disposal methods • Long term environmental liabilities • High costs for remediation • Increasingly stringent regulatory environment(s) • Negative public perception (land contamination / water use) • Example: Ontario Reg. 347 mandates pre-treatment of all waste prior to haulage as at August 2007
Benefit Statement • WWT Simplicity / one step process • Unique introduction of dry reagents • Low cost equipment, low energy requirement vs. common polymer & centrifuges • Proven results • BioSolids Treatment • Convert to a solid within minutes • Pass Paint Filter and Slump tests • Surpassed regulations for Encapsulation of heavy metals and organics • Re-usable as a fertilizer Mandated compliance August 2007
Leamington Project Potential and Logic Up front treatment potential and benefits Reagent new experimental blend* 2% to 18% immediate Benefits One step dry addition Reduced solids to clarifier Enhanced sludge solids to day tank Enhanced sludge sent back-end treatment Low cost equipment and energy Back-end treatment potential and benefits New experimental blend** 4 to 8% to 56% in 72 hours Benefits One step dry addition Enhanced sludge production Combined upfront and back-end treatment and benefits 2% to 56 % without any energy Benefits Low energy Slow shear mixing Rotary Screener vs. Centrifuge high equipment energy cost Reduced odors and pathogens Reduced weight and volume, 200% of current reagents vs. 2% Reduced natural gas cost for Drier operation
