  1. Treatment of Turkey Processing Wastewater Using Sand and Sand/Textile Bioreactors

    In order to effectively treat wastewater with sand bioreactors, slow degrading objects must be removed. This study compared coarse sand and pea gravel to textile chips in order to discover which option was a better pretreatment. To view full text, click h ...

  2. Pretreatment of Turkey Fat in Wastewater in Sand Bioreactors

    Due to slow decomposition, typically fat, oil, and grease in wastewater is hard to treat. In this study, two types of sand bioreactors were set up to treat the wastewater. One set had varying depth of coarse sand while the other had varying depth of pea g ...

  3. A Case Study of the Lake Panorama Management District

    An on-site wastewater management district was formed in Iowa in 1980. Quickly the committee started formulating rules and regulations. Failing systems were corrected. Using this district as an example can form other districts. ...

  4. Empirical Models for Effectiveness of Single Pass Sand Filters for Wastewater Treatment

    Two empirical models for effectiveness of single pass sand filters for wastewater treatment were developed. Sand size and depth were found to be the two most important factors when it comes to the performance of the sand filters. ...

  5. Onsite Wastewater Management: A Model for Success

    An expert panel identified elements for success in wastewater management. Two important elements are forming and sustaining a management entity. ...

  6. Twenty Years of Success in Septic System Management

    Since 1980, the amount of homes has doubled around Lake Panorama. Inspections of wastewater systems began in 1986. The malfunction rate is only 1%.  ...

  7. Water Augmentation Through Onsite Wastewater Management

    In 1972, the Colorado legislature allowed for water augmentation plans. Augmentation plans can be used to maximize the use of water. The Crystal Lakes Development Company developed the first water augmentation plan. In 1974, water was limited for benefici ...

  8. Design of Delivery Device for Chlorine Dioxide Disinfection

    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 ...

  10. Biodegradation of Vegetable Oils Using Fixed-Film Systems

    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 ...
