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...

The characterization and physical-chemical treatability of log pond waters

Creator:: Blanton, Guy Ivan
Abstract:: The treatability of waters from four log ponds in Oregon by physical and chemical treatment methods was investigated. Treatment processes included sand filtration, activated carbon contact and coagulation with aluminum sulfate. Preliminary studies were made at each log pond to determine the homogeneity of the pond water for sampling purposes...

Excretion of viable salmonellae by Salmonella-fed, chlorine-treated nematodes

Creator:: Smerda, Susan Mae
Abstract:: The role of nematodes (Diplogaster lheritieri Maupas 1919) as excretors of pathogenic organisms was studied. Salmonella typhi and Salmonella wichita were fed to nematodes for two days. The nematodes were surface sterilized with free chlorine. The activity of the chlorine was stopped by the addition of sodium thiosulfate followed by...

Kinetics of biological contact beds

Creator:: Seaders, John
Abstract:: The influence of media size upon the effective removal of organic waste from a liquid substrate was studied by the use of three experimental trickling filters under a set of uniform operating conditions. The range of experiments involved hydraulic loadings of increasing magnitude and of constant organic strength. The trickling...

An evaluation of variables affecting the virus removal capabilities of the coagulation-filtration process

Creator:: Chapman, Robert Lyle
Abstract:: The capabilities of the coagulation-filtration process for virus removal were evaluated by constructing and operating a one step, 2 gpm coagulation-filtration pilot plant. Multi-media filters were used without pre-coagulation and sedimentation. A T2 bacteriophage was used as the indicator organism. The plant was operated under a variety of conditions in...

The character and biological treatability of log pond waters

Creator:: Hoffbuhr, Jack Wayne
Abstract:: A study was conducted to determine the chemical nature and the biological treatability of log pond water. Various analyses including total solids, volatile solids, suspended solids, dissolved oxygen, pH, COD, BOD₅, BOD₂₀, total Kjeldahl nitrogen, nitrate nitrogen, phosphate, and PBI were performed on water samples from each of the four...
