Transcript

  • 1. Waste Water Treatment Suggestions for Integrating the Living Machine with Campus Life By: Professor Lynn Polasek Biology Department LAVC
  • 2. Sustainable Science Project • Goals • Support Education • Save Money • Process Wastewater Safely & Reliably • Beautify the Campus • Role Model Sustainable Practices
  • 3. What is a Living Machine? A series of interconnected man made ponds that cleans up wastewater.
  • 4. Eco-engineering Practices for the Future Depending on its size, it can process varied amounts of wastewater from 300 gallons/day to 750,000 gallons/day The Processed Wastewater Meets Tertiary Standards Biolochemical Oxygen Demand 10-20mg/L Total Suspended Solids 10-20mg/L Total Nitrogen 10-26mg/L
  • 5. The Value of the Wetlands A Living Machine is like a man made wetland • Form Stable Communities that Process Waste – Linked via biological processes • How one living species effects another – Linked via chemical processes • Photosynthesis • Respiration • Biogeochemical Cycles – carbon, nitrogen, phosphorous cycles – Linked via physical processes • Climate, water availability, gravity
  • 6. Wetlands serve as nature’s own H20 treatment plant • Produces some of the purest water in the world • Trapping sediment • Absorbing, diluting & degrading toxic pollutants • Performing biogeochemical cycles • Acting as a natural filtration system • Can even process human sewage and animal waste
  • 7. They function as the “kidneys of the landscape” Complex roles in regulating water flow & purification
  • 8. Future Plans for LAVC Campus? Students could be a part of the maintenance of the living machine. Constructed wetland/wildlife habitat functions as an outdoor classroom & living lab
  • 9. Representative Living Machine Projects They have been used successfully by businesses for many years! • YMCA Camp Seymor, WA • 10,000gal/day sewage/reuse – 2002 • Smugglers Notch Resort, VT • 40,000gal/day sewage – 1999 • Darrow School, NY • 8,600 gal/day sewage – 1998 • Noorder Diereupark Zoo • 220,000gal/day sewage/reuse – 2001 Emmen, Netherlands
  • 10. A Horizontal Flow Wetland Living Machine System Naturally provides filtration & treatment of water for purification Built Spring 2001 by Lynn Polasek • It works due to the interrelationships of: – Microbes – Plants – Animals – Sunshine
  • 11. Producer Chamber Plants, Photosynthesis, Bottom of Food Chain, No Large Predators
  • 12. Consumer Chamber Flowing Water, Nutrient Consumption, Large Consumers, Aquatic Plants
  • 13. Decomposer Chamber Bio-filtration, Saturated Soil, Nutrient Conversion, Nutrient Recycling
  • 14. Wetland Chamber Natural Filtration, Bioremediation, Nutrient Rich, Biodiversity
  • 15. Succession & Extinction Consumer Chamber Fall 2001 Fall 2004
  • 16. Succession-Extinction Producer Chamber Spring 2001 Fall 2004
  • 17. • System is 4 years old • Chemical free • Pest free • Odor free
  • 18. A Self-Sustaining Community • Break down waste using – Microorganisms, small invertebrates & plants – Diverse flora & fauna populations in a series of environments • Recycle essential molecules in process that is – Stable – Robust – Consistent – Reusable • Build new life – Together aerobic & anaerobic organisms will provide a broad range of biochemical processes that are necessary for a self- sustaining community.
  • 19. The microbes do most of the chemistry on the planet. They set the stage for plants & animals to follow.
  • 20. Types of Living Machine Systems They vary widely in size, design & ecological capacity. • Vertical Flow Wetland Living Machine System • Tidal Flow Wetland Living Machine System • Good Water 2 Living Machine System • Horizontal Flow Wetland Living Machine System
  • 21. Horizontal Flow Using Small Interconnected Tanks Biodiversity Provides Ecosystem Stability
  • 22. Innovative Designs Include An eco-park with a living machine • Utilizes the forces of: – Water Flow – Collection – Catchment – Water Treatment – Water Re-use • Ecological Capacity – Create more eco-capacity to the area than before
  • 23. Water and Waste Reclamation • Treat Storm Water • Treat Waste Water • Showcase the Effluent • Provide Wildlife Habitats • Restore Ecological Balance – Geology – Topography – Hydrology – Soils – Biotic Communities – Human Goals
  • 24. Tidal Flow BOD & TSS < 5mg/L and TN <10mg/L • Superior nitrogen removal • Compact footprint • Series of 4-6 tidal flow cells – Periodically flood/drain • Achieve tertiary standards • No mechanical aeration • No clarifier • Bio-solids digested in place • Computer controlled • Plant friendly • Odor free
  • 25. Good Water 2 BOD & TSS 10mg/L and TN <20mg/L • Replicates nature more • Biological nutrient removal – Plant roots grow on racks – Biofilms grow on roots – Biosolids retained on roots – Invertebrates thrive on biofilms & biosolids • 4-6 aerated tanks – No clarifier – Ends with vertical flow • No free water surface
  • 26. Vertical Flow BOD & TSS < 20mg/L and TN <26mg/L • No free water surface – Reduces risk human contact – Reduced mosquito breeding • Compact • Viewing/sampling sumps – Different parts of system • Re-circulating gravel filter • 3 Tanks – Planted wetland cell – Filter septic tank – Re-circulation tank
  • 27. Produce high quality effluent with potential for reuse. Agricultural (non-edible) & landscape Industrial activities: cooling & process needs Ground water recharge Recreational/environmental use Parks & wildlife habitats Non-potable urban uses: Toilet flushing, construction Stable operation. Aesthetic appeal.
  • 28. Oberlin College Adam Joseph Lewis Center for Environmental Studies • Wastewater flow: – 2 underground anaerobic reactors – 2 covered aerobic reactors – Indoor series of reactors • Hosts aquatic plants/orgs. – Clarifier • Biosolids recycled/removed – Constructed Wetland – Effluent disinfected w/ UV system
  • 29. Oberlin College in Ohio
  • 30. Rent the Grounds for Special Occasions
  • 31. The Living Lab Combination Greenhouse, Laboratory, Classroom and Living Machine
  • 32. The Living Lab 2003 Taos County New Mexico Series of tanks inside a greenhouse • Promote ecological literacy • Students learn how to: – Elementary schools – Harness waste & promote – Middle schools beneficial relationships to provide clean water, food – High schools and shelter. – General public • Living Classroom – Hands on lessons • Ecology • Agriculture • Aquaculture • Engineering • Environmental Restoration
  • 33. Living Lab Inside a Greenhouse • Powered by the sun-collects – Rainwater • To grow fruits & vegetables – Storm Water • To process in living machine • Study relationships – Bacteria, algae, protozoa, plants, animals – Digest organic compounds in waste water • Produces – Clean water, food, building materials
  • 34. Concept of Living Lab Waste of one system is food for another. Students are immersed in an environment that thrives! There is no such thing as waste in nature!
  • 35. Creating a Schoolyard Wildlife Habitat • Support Wildlife • Support Native Plants • Provide Human Food • Create Beauty & Comfort • Xeriscape • Protective Landscaping – Decrease utility bills • Create an insectary – Attract/support/breed beneficial insects that kill pests

  • 51. Final Comments Living Machines can process any kind of waste water. • After building and maintaining a living machine for 6 years I can say that with a balanced ecology: – It smells good – It always looks beautiful & supports wildlife – It needs a constant water source to process – It is basically self supporting and requires minimal maintenance • Occasional weeding • Occasional cleaning of the pipe system from algae growth – Like a roto-rooter clean out – It’s not a problem if periodic clean out traps are placed along the pipes
