  • Transport and transformations of nitrogen compounds in effluent from sand filter-septic system draintile fields

    Creator:
    Bushman, Jennifer L.
    Abstract:
    A total of 44 intermittent sand filter-septic systems, in five counties of Western Oregon, were sampled over a three-month period during the summer of 1995. The sand filter systems varied in age from 36 months up to 167 months (3 to 13.9 years). Liquid samples were taken from the septic...

  • An ammonia stripping and recovery system for animal wastewaters

    Crown, Julia K.
    Abstract:
    Traditionally, livestock operations were small and combined with cropping operations. This allowed farms to be self-sustaining because nutrients were constantly recycled on the farm. Since the Haber-Bosch chemical process was patented, crop farmers turn to industrial fertilizers when soils nutrients are depleted. Animal and plant operations diverged, functionally separated, and...

  • Potential of a fungus, Acremonium sp., to decolorize pulp mill effluent

    Creator:
    Lesley, Dawn
    Abstract:
    This project explored the feasibility of using fungi in a constructed wetland for the treatment of pulp mill effluent. The effluent is high in dissolved lignins (some of which are chlorinated), which have proven very difficult to degrade biologically. Mindful of work done with the (terrestrial) white rot fungi, especially...
