  • Treatment of activated sludge process effluent by carbon adsorption

    Creator:
    Davis, Stewart Lee
    Abstract:
    An evaluation of the service time of an activated carbon adsorption column and the organic carbon removal efficiency treating activated sludge process effluent was completed at aerator detention times of three, five, and ten hours. Parameters used for evaluation of treatment were biochemical oxygen demand, chemical oxygen demand, total organic...

  • A torsional investigation of a concrete I grider

    Creator:
    Martin, Roy Charles
    Abstract:
    This paper investigates a particular bridge construction technique which could result in a significant torsional moment. The structural member under consideration is a prestressed concrete girder for which no torsional consideration is made. Torsional shear stresses can be adequately approximated for an I-shaped girder. Laboratory model tests were performed to...

  • Aircraft washrack wastes : their characteristics and treatment

    Creator:
    Evans, David Roland
    Abstract:
    Oils, greases, and grit which collect on an aircraft during flight are removed on the U. S. Air Force washracks using an alkaline, water-base cleaner. Waste-flows from these washracks may include in addition to free oils, emulsified oils, and alkaline, water-base cleaners several other constituents such as acid skin brightners,...

  • A method of seismic design for prestressed concrete highway bridge girders

    Creator:
    Lam, Kwok To
    Abstract:
    The effects of vertical ground motion are particularly significant in the design of highway bridge girders. Conventional codes do not recommend methods for solving the problem. The intent of this work is to suggest an approach for such design. A set of curves for velocity spectra which are the average...
