Modeling estuary pollution by computer simulation

Creator:: Grenney, William J.
Abstract:: A digital computer model was developed to simulate the time and space distribution of a dissolved pollutant in an estuary. The program is basically a one-dimensional finite-difference model, but two dimensions can be represented by attaching together several one-dimensional channels. The influence of convection, dispersion and decay are included in...

An evaluation of the oxygen resources in the lower Willamette River during a critical low flow period

Creator:: Kari, Earl Nyhus
Abstract:: The lower Willamette River, located between river mile 4.0 and 26.5, is the most seriously polluted section of the Willamette River Basin. Low dissolved oxygen concentrations of 2.0 to 3.0 mg/1 are observed annually in this section of the river due to the pollutional loads discharged into it. Waste discharges...

Removal of dieldrin from water by granular-activated carbon

Creator:: Hardman, Michael Harvey
Abstract:: A 9.0 ppb solution of dieldrin in water was passed through a granular-activated carbon bed at the rate of 4 gpm/sq. ft. The performance of the carbon was monitored from sampling ports at bed depths of 2-1/4 and 8-1/4 inches. Isotherm tests were also run with a 9.0 ppb dieldrin...

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,...

Factors affecting slime accumulation in fiberboard mill process water

Creator:: Minelli, Michael Philip
Abstract:: The objectives for this study were to determine the causes of slime formation in activated sludge treatment and to recommend possible control measures. The primary problem was a seasonal filamentous bulking which was caused by the mold, Geotrichum candidum. During the winter, mycelial fibers appeared and formed a free floating...

The fate of specific organisms in a receiving stream

Creator:: Henshaw, Thomas Lamond
Abstract:: One of the major items in any program of municipal sanitation is the double problem of water supply and waste water disposal. Since streams are the general source of water supply and also the final receptacle for sewage, this dual use of the stream often leads to complications. Sewage and...
