  • Advanced Enviro - Septic™ Wastewater Treatment System Septic Tank Effluent Filters and Charco al (Odor) Filters NOT Recommended

    Abstract: Effluent filters are installed in the outlet from the septic tank with the intended purpose of retaining solids inside the tank, preventing them from entering the treatment system and/or dispersal field. The concern is that if solids escape from the septic tank, they could cause clogging of the system components or the soil interface. While this may be a legitimate concern for some ...

  • Algae Enumeration and Identification

    Algae Enumeration and Identification Algae are ubiquitous in virtually all aquatic environments and are important bioindicators of water quality. They are frequently used to assess and monitor the health of aquatic systems. On the other hand, they are also responsible for imparting undesirable flavors to potable water supplies and pose potential health threats, particularly during algal blooms. ...

  • Elimination of NH3 and odor from composting by biotrickling filter and preliminary exploration on molecular biology

    A biotrickling filter was focused on treatment of odorous NH3 gas, along with volatile organic compounds (VOCs) and other odorous gases during cattle manure composting. The biotrickling filter could treat NH3, the main composition, with removal efficiencies of close to 100% because NH4+ was bio-oxidized in the biofilm to NO3− resulting final NO3− concentrations of about 1000 mg/L. Results of ...

  • Application of Biotrickling Filter for Odor Control at The Morris Forman Wastewater Treatment Plant

    Pilot-scale study of a biotrickling filter using synthetic, high surface area media was undertaken by MSD Louisville, with the intention of saving the high cost of operating thermal oxidizers. Currently, two recuperative thermal oxidizers are used to treat odorous emissions from various sources. The pilot study showed that it is possible to treat hydrogen sulfide and organic sulfur compounds at ...

  • Significant Improvements in Biofilter Performance for H2S and VOC Removal Using Biotrickling/Bioscrubber Technology in the Aeration Distribution Plenum System

    ABSTRACT Biofilters can handle the removal challenge of a diverse mix of complex odors and VOCs. However, there are significant limitations in handling levels of hydrogen sulfide (H2S) loadings above 10 ppm. High levels of H2S loading in biofilters will create an increase in the acidithiobacillus colony causing an overproduction of acid. This will destroy all other biodegrading ...
