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,...

Alum coagulation in conjunction with the activated sludge treatment of corn processing waste water

Creator:: Jensen, Harold LeRoy, III
Abstract:: The treatment of waste water from a corn freezing process by activated sludge with the aid of alum coagulation was investigated. Both high and low energy level systems were observed with good flocculation occurring at the low energy level. Because poor flocculation occurs at high energy level conditions, alum was...

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...

Persulfate oxidizable carbon as an index of organic pollution in wastewater

Creator:: Purkerson, L. Lee
Abstract:: Methods for the detection and measurement of waste materials in water have lagged far behind the many complex problems facing workers in the water pollution field. The present study introduces a new method for the detection and measurement of organic pollution in water. This new method, the persulfate oxidation, is...

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...

Specific indicator organisms can define the magnitude and origins of non-point pollution in rural environments

Creator:: Lamka, Karla Gail
Abstract:: A comprehensive study was made on the impact to surface and ground water pollution by a recently populated rural neighborhood located in the foothills of western Oregon. A stream originating in a limited access forest and flowing through a modern zoned housing development was routinely monitored. Sampling was performed during...

The effects of engineered coatings and natural organic matter on nanoparticle aggregation

Creator:: McDowell, Shannon A.
Abstract:: In order to better predict the aggregation state of nanomaterials, the factors that influence aggregation must be understood. The combined effects of natural and engineered coatings have been shown to factor into nanoparticle aggregation behavior in preliminary research. In this study, aggregation behaviors of gold nanoparticles with two different engineered...

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...
