  1. Model for Success in Onsite Wastewater Managment

    https://setll.osu.edu/node/154

    A panel of experts discusses the elements for success in onsite wastewater management. It was recommended to be creative, empathic, and dependable. ...

  2. Design of Delivery Device for Chlorine Dioxide Disinfection

    https://setll.osu.edu/node/153

    If wastewater is dispersed through irrigation without being disinfected, serious health effects could take place. Avantec Technologies has created an alternative to traditional disinfection services. Carbon dioxide gas is used to disinfect, which kills vi ...

  3. The Effects of Year-Round Irrigation of Landscape Plant Quality and Health in Ohio

    https://setll.osu.edu/node/152

    Only 6.4% of Ohio’s land area is suitable for traditional septic systems. Almost half of Ohio’s land area has shallow depth soil. In these areas, irrigation as a dispersal method could improve landscape plant quality. 33% of plants died in the non-irrigat ...

  4. 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. ...

  5. 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. ...

  6. 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 ...

  7. 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 ...

  8. Biological Treatment of Cheese-Processing Effluent with Gravel/Sand Filtration

    https://setll.osu.edu/node/145

    This laboratory study assessed the feasibility of sand/gravel bioreactors to treat cheese-processing wastewater. Within 210 days, the BOD 5 had a removal rate of >99% and the COD has a removal rate of 85%. There were no clogging issues during the study ...

  9. 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 ...

  10. 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. ...
