  3. Presentation Outline • Water Shortage Problem – Sustainability • Current On-site Septic • Solution - Onsite Water Re-use • Wastewater Chemistry • How Aerobic Treatment Works • Questions (c) Nobska Technologies, Inc. 2010

  4. Use Exceeds Supply (c) Nobska Technologies, Inc. 2010

  5. Conventional Septic Tank • 3 layers • Bottom – Sludge • Top – Scum & Grease • Middle - Clear (c) Nobska Technologies, Inc. 2010

  6. Septic Tank Configuration Water leaves Septic Tank to Leachfield/Drainfield (c) Nobska Technologies, Inc. 2010

  8. Biochemical Oxygen Demand (BOD) • BOD – One of the most commonly measured constituents of wastewater • BOD measures the strength of effluent released to environment, ultimately a body of water • BOD contains inorganic and organic materials. • Organic – Carbon based, decomposed by bacteria • Oxygen required for process – BOD5 is a measurement of quantity of oxygen consumed in a five (5) day period by the microorganisms Source: “Basics of Wastewater Treatment”, available at http://www.barnstablecountyhealth.org/AlternativeWebpage/Basics/Basics.htm; and “Small and Decntralized Wastewater Management Systems”, by Crites and Tchobanoglous, McGraw Hll 1998. (c) Nobska Technologies, Inc. 2010

  9. Biochemical Oxygen Demand (BOD) • High BOD Problem – High BOD water released into other waters can deplete oxygen • Causes fish kills • Algae Blooms – Acts as plant food for algae • Aerobic Treatment Technology – designed to reduce BOD greater than done by conventional septic system – provides opportunity for water re-use Source: “Basics of Wastewater Treatment”, available at http://www.barnstablecountyhealth.org/AlternativeWebpage/Basics/Basics.htm; and “Small and Decntralized Wastewater Management Systems”, by Crites and Tchobanoglous, McGraw Hll 1998. (c) Nobska Technologies, Inc. 2010

  10. Nitrogen • Nitrogen – Contained in Human Waste • Septic Tank – Nitrogen breaks down into Ammonia (NH3) • Ammonia – primary form of nitrogen leaves septic tank • Conventional Septic Configuration – most Ammonia breaks down into Nitrate below the leachfield where is oxygen present Source: “Basics of Wastewater Treatment”, available at http://www.barnstablecountyhealth.org/AlternativeWebpage/Basics/Basics.htm; and “Small and Decntralized Wastewater Management Systems”, by Crites and Tchobanoglous, McGraw Hll 1998. (c) Nobska Technologies, Inc. 2010

  11. Aerobic Treatment – 2 Step Process Ammonia converted to nitrogen gas Step 1: Nitrification – Aerobic Ammonia to Nitrite to Nitrate Requires Oxygen - Mediated by Aerobic Bacteria Step 2: Denitrification – Anerobic Nitrate to Nitrogen Gas Needs Low Oxygen – Mediated by Carbonaceous Bacteria Source: “Basics of Wastewater Treatment”, available at http://www.barnstablecountyhealth.org/AlternativeWebpage/Basics/Basics.htm; and “Small and Decntralized Wastewater Management Systems”, by Crites and Tchobanoglous, McGraw Hll 1998. (c) Nobska Technologies, Inc. 2010

  12. Aerobic Treatment Step 1: Nitrification NH4 + 3/2 O2 NO2- + 2H+ + H2O NO2- + 1/2 O NO3 Step 2: Denitrification NO3- + 5/6 CH3OH 1/2 N2 + 5/6 CO2 + 7/6 H2O + OH Source: “Basics of Wastewater Treatment”, available at http://www.barnstablecountyhealth.org/AlternativeWebpage/Basics/Basics.htm; and “Small and Decntralized Wastewater Management Systems”, by Crites and Tchobanoglous, McGraw Hll 1998.
