1 Gary Ferrante, P.E. Greeley and Hansen, LLC Kevin Higginson, P.E. Greeley and Hansen, LLC Tom Welch - Schwing Bioset Eva Deyo Immokalee Water & Sewer District

2 Small unincorporated rural community located in Collier County Permanent Population of 24,000 (2010 Census) One WWTP, recently expanded from 2.5 MGD to 4.0 MGD

3 Class B biosolids 6 Land Application Sites Pending FDEP Regulation Changes Expected to limit land application of Class B biosolids IWSD directed their consultant to look at biosolids disposal alternatives that would satisfy pending regulations

4 2007 Alternatives Evaluation compared several alternatives FDEP regulations pending Recommended piggybacking onto sludge dewatering & hauling contract with Synagro

5 Florida Biosolids regulation, Chapter , F.A.C., became effective on August 29, 2010 Watershed Basins Most sites, if not all sites, are expected to end land application by 2014 About half of the original sites are now Inactive Decreasing volume

6 $60.00 Cost per 1,000 Gallons $50.00 $40.00 $30.00 $20.00 $10.00 $

14 Schwing Bioset Screw Press

15 Totally Enclosed Contains dust Contains odors Ideally suited to operate as a regional facility: Accommodate fluctuations in percent solids of the incoming wet cake Accommodate rapid increases and decreases in throughput Accommodates biosolids from any wastewater process (aerobic, anaerobic, etc) without any modifications to operations.

16 Fully automated Chemical feed rate adjusted based on reactor temperatures for Phase 1 Long-term product stability Regional facilities and fertilizer marketing operations require a product that is stable and can be stored for extended periods to span growing seasons and/or periods of unstable weather. Easy to Operate and Maintain Simple processes that do not require multiple shifts of operators or complicated and/or potentially dangerous operating conditions are generally preferred technologies.

17 Screw Press Low Power Consumption Low Wash Water Consumption High Throughput Wash cycles do not interrupt dewatering process Simple Start-up & Shut-down
