  1. Investigating methods for Preventing Cold Induced Freezing of Irrigation Sprinklers

    https://setll.osu.edu/node/150

    In order to have year-round dispersal, sprinklers needed to be protected from sub-freezing temperatures. The use of heating tape may lessen delays. ...

  2. Economic Analysis of Poorly Sited Septic Systems: A Hedonic Pricing Approach

    https://setll.osu.edu/node/149

    Untreated or partially treated wastewater could lead to adverse health effects along with a loss of property valuation. Properties that are deemed optimal for wastewater treatment are valued higher that those deemed sub-optimal. ...

  3. Effectiveness of Onsite Wastewater Reuse System in Reducing Bacterial Contaminants Measured with Human Specific IMS/ATP and qPCR

    https://setll.osu.edu/node/148

    To increase confidence in the interest of reusing reclaimed wastewater, fecal pollutants detection options needed to be researched. IMS/ATP is a way to detect fecal contaminants. ...

  4. Biodegradation of Vegetable Oils Using Fixed-Film Systems

    https://setll.osu.edu/node/147

    To determine the feasibility of using sand bioreactors to treat vegetable oil waste, a laboratory study was evaluated. Column bioreactors were constructed of a mixture of lipophilic isolates and sand.  The combination was able to remove 80% of biomaterial ...

  5. Removal of Butterfat COD and BOD5 in Inoculated Sand Columns

    https://setll.osu.edu/node/146

    While investigating the feasibility of the biodegradation of butterfat using sand bioreactors, the study found that there was a high degree of COD and BOD 5 removal. Measuring the ATP determined the accumulation of biomass in the sand bioreactors. When su ...

  6. High Fat Wastewater Remediation Using Layered Sand Filter Biofilm Systems

    https://setll.osu.edu/node/144

    To investigate the feasibility of sand bioreactors treating butterfat supplemented with detergent, three layer reactors and two layer reactors were compared. Both options showed great COD and BOD 5 removal. However, the two layer bioreactors became clogge ...

  7. Biological Treatment of Turkey Processing Wastewater with Coarse/Fine Sand Filtration

    https://setll.osu.edu/node/142

    This study researched how well organic mater and nutrients were removed by course/fine sand filtration systems. Ammonia and phosphorus were removed while the system was in operation. ...

  8. Transformations and Accumulations of Carbon in Gravel/Sand Filters Treating Cheese Processing Wastewater

    https://setll.osu.edu/node/141

    This study discovers that after carbon gets trapped in the gravel/sand filter, it converts from organic to inorganic.  ...

  9. Pretreatment of Animal Fat Through Course Sand Filters

    https://setll.osu.edu/node/139

    Due to slow decomposition, typically fat, oil, and grease in wastewater is hard to treat. This study investigated weather adding a pea gravel cap above the coarse sand would help with pre-treatment of the wastewater. The results indicate that the pre-trea ...

  10. Comparison of Applications Strategies for Fixed-Media Treatment of Turkey Processing Wastewater

    https://setll.osu.edu/node/132

    Demand-dosing and time-dosing were compared during this laboratory study. Both systems achieved >99% BOD 5 removal rates. There was no clogging observed in either system. The study concluded that there is no significant difference in systems. ...
