1. Boiler Green Initiative (BGI)Design Review December 11, 2009 Neil Armstrong Hall of Engineering Boiler Green Initiative

2. Agenda Hillel House • Overview of team • Hillel House • Wind Turbine • Bio Energy • Questions Boiler Green Initiative

3. Rachel Machbitz, Team Leader Bio Energy Hillel House Wind Turbine Sean Zimmerman, Project Leader Beth Doering, Project Leader Jared Freyer, Project Leader and Webmaster Scott Sylvester Isaac Payne Fahad Ahmad Yuanhua Cheng Bryson Maikranz Hannah Keller Anthony Christie Team Overview: Organization Hillel House Joseph Cox LexiStehr Amber Ramsey Liz Hoffa Katie Jones Boiler Green Initiative

4. Goals of the Project Hillel House • Focuses this semester: • To prevent soil erosion • Make the property more aesthetically pleasing • Complete rain garden design • Secondary goals • Make the Hillel House more energy efficient • Determine alternative energy sources • Community education

5. Project Partner • Phillip Scholssberg • Hillel House Director • Hillel is the Foundation for Jewish Campus Life • Located on State Street and Waldren Street

6. Feasibility Chart for Alternative Energy Possible Not Practical Practical Boiler Green Initiative

7. Rain Garden Design Criteria Hillel House • Criteria • Must be at least 10 feet from building • Garden should optimize backyard drainage • Must have outlet for rain garden overflow • Size of garden should be a certain proportion of the roof area needing to be drained • depends on soil type and roof area needing to be drained Roof section which drains to backyard Indicates backyard drainpipes Boiler Green Initiative

8. Design Variables • For sizing the garden • Soil texture (sand, silt, clay…) • Soil infiltration rate • Rain intensity • Area of roof needing to be drained and area of garden • For garden location • Elevations • Aesthetics Boiler Green Initiative 8

9. Design Variable: Infiltration Rate • Soil Type: Carmi • Well drained, deep sand/gravel • Sandy loam surface texture • Infiltration test • Surface: 3.17 in/hr • Subsurface (9 in): 3.75 in/hr • Error • 3D movement • Time constraints Boiler Green Initiative

10. Design Variable: Soil Type Rain Garden Size Factors (Considine, Bannerman, & Baker, 2003) Size Factor * Area needing to be drained = size of rain garden Soil texture – sandy loam/loam Size factor ≈ .12 Rough rain garden size = 124 ft2 Boiler Green Initiative

11. Design Variable: Rain Intensity Using this intensity, input ≈ 137 ft3/hr Figure : Rain Intensity for Lafayette, IN for T-Year Events – The longer the storm the greater rainfall depth for T-Year events. http://www.in.gov/dnr/water/4897.htm Boiler Green Initiative

12. Design Variable: Elevations Hillel House Hillel House *All measurements are inches 0 N 100 Parking Lot 200 2 300 0 -2 Patio -4 400 Garden 500 1000 900 800 700 600 500 400 300 200 100 0 12 Boiler Green Initiative

13. Water Balance Calculations • Basic mass balance calculation • Retained water = Inputs – Outputs Input: Outputs: garden charging rate Top view, rain garden catchment Boiler Green Initiative

14. Water Calculation Results Hillel House For the following 2 year rain events, all water is retained by the barrel and garden. Therefore, no water runs off. Boiler Green Initiative

15. Discharge Calculations Team Name • Assumed laminar, incompressible fluid • Bernoulli’s Eqn. – used to calculate velocity in pipe • Manning’s Eqn.– used to calculate fluid velocity in open channel • Discharge Eqn. – used velocity to find discharge V = velocity in ft/s p = pressure (psf) g = force of gravity (ft/s^2) ρ = specific gravity z = elevation (ft) n = surface roughness coefficient R = hydraulic radius (ft) S = slope of energy line º slope of bed V = velocity (ft/sec) V = velocity (ft/s) A = area (ft^2) Q = VA Boiler Green Initiative

16. Flow Diagram Hillel House *Elevations are relative to an arbitrarily set benchmark 16 Boiler Green Initiative

17. Flow Diagram Hillel House *Elevations are relative to an arbitrarily set benchmark 17 Boiler Green Initiative

18. Rain Barrel Hillel House • Why use a rain barrel? • Increase water-holding capacity • Environmentally friendly way to use water • Water storage for use during dry periods during summer • 60 gal would provide .85 in, or 53.3% of available water to plants • 60 gal costs $0.15, however customer would like the barrel • Possible problem: mosquitoes Boiler Green Initiative

19. Rain Barrel Design Hillel House Drain pipe 4 in 60 Gal. Rain Barrel .38 % slope Slip cap Valve 4 in Trench Slope = .38 % 2 in Rain Barrel Stand www.plumbingstore.com/pvc.html www.alibaba.com/product/satmip-10832960-10638 Boiler Green Initiative

20. Rain Barrel Stand Dotted line is rain barrel Rain barrel is 28 inches in diameter 32 in 8 in 8 in 32 in

21. Rain Barrel Decision Hillel House Home Depot 60 Gallon Deluxe Rain Barrel $99.99 • Durable • UV-stable 25% recycled resin • Lid can be removed • Plastic, can drill holes into it Boiler Green Initiative

22. Walkway for Rain Garden Why Brick? • Its inexpensive and fits within our budget • Its fairly simple to install • Brick is usually very durable for many years • Very aesthetically pleasing Our Choice • Oldcastle Holland Paver Tan/Charcoal • Purchased locally from Lowes Department store • Website claims this type is best suited for walkway and requires no mortar

23. Brick Options for Walkway

24. Flowers for Rain Garden Hillel House • Constraints: • Sandy/Loam Soil • Tolerant of partial shade • Moisture conditions • Native plants • Chose according to sun/water requirements • Perennials http://davesgarden.com/guides/pf/go/125593/ http://www.critsite.com http://davesgarden.com/guides/pf/go/56961/ Marsh Blazing star $26.76 WhiteTurtlehead • $5.49 False Aster $6.10 http://davesgarden.com/guides/pf/go/73540/ http://davesgarden.com/guides/pf/go/1014/ http://davesgarden.com/guides/pf/go/24351/ http://davesgarden.com/guides/pf/go/54061/ Yellow Columbine, Golden Columbine $14.95 Celandine Poppy, Wood Poppy $34.95 • Red Milkweed • $5.18 Day Lily $32.06 24 Boiler Green Initiative

32. Wastewater Treatment Plant Need Bio-Energy • Sustainability of the digester project at West Lafayette Waste Treatment Facility. • Goals • To reduce operating cost of WWTP • To decrease quantity of waste to recycle • To increase methane production • To maximize usage of available capacity of renovated digesters 3

33. Goals of the project Bio-Energy • To help the community become more green by: • Reducing quantity of Purdue waste food currently going to landfills • Identify additional sources of waste food substances for the digestion process 4

34. Background Research Bio-Energy • Anaerobic Digester http://www.poweralternatives.com/power_companies/details/company/agcert-international.html 5 6

35. Background Research Bio-Energy • Researching a replacement to the activated carbon, silica gel is currently being looked at. • Toured dining facilities to better understand current waste food collection and treatment methods • Research other potential waste food providers • Possible contribution in tons 6

36. Bio-Energy Background Research • Currently using 500 lb. activated carbon at approximately $2,000 per cycle which is approximately two to three months • Silica gel as a new media for filtering the biogas • Silica gel is a cheaper chemical and can be made at WWTP • Need to determine the best chemical form and composition of the silica gel for the biogas filtration 7 7 7

37. Alternative Research Ideas Bio-Energy • Improving function of digester by adding other microorganisms. • Removal of siloxanes from biogas with biofiltration via Pseudomonas • Boost in methane production from Lactobacillus 8

38. Background Research Bio-Energy • Food Pulper (Giant Garbage Disposal) Researching Specifications through these companies: Untha Muffin Monster http://www.prowastestrategies.com/images/319_Somat_Super_60.jpg 9

39. Future Plans Bio-Energy • Continue to explore potential waste food providers • Recommend replacement technology for carbon treatment facilities • Work with WWTP to integrate team’s proposals into current operations 10

40. Statistics Bio-Energy • Purdue is giving 5 tons of pulp per week • This adds up to an annual savings of $10,000 in landfill costs, reduced labor, and fuel savings • West Lafayette Waste Water Treatment Facility • This added food saves them annually $4,000 in electricity and natural gas savings. 11

41. Bio-Energy Budget • Our current budget is small due to the heavy research being done at this phase • Considerations were made to purchasing silica beads. However, after a meeting with Dr. Michael Harris, Assistant Dean of Engineering, we realized that we could produce the silica gel ourselves 12
