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...

The effect of elevated pressure on the activated sludge process

Creator:: Godsil, Patrick James
Abstract:: A study of the effect of elevated pressure on the activated sludge waste treatment process is presented. The method of study involved a comparison of two laboratory, batch type, activated sludge units. One unit was operated at atmospheric pressure as a base control and the other operated at elevated pressures...

The effect of elevated pressure and high shear on oxygen uptake rates in activated sludge

Creator:: Streebin, Leale E.
Abstract:: The purification capacity of an activated sludge process is highly dependent of the rate of oxygen transfer from the air to the microorganisms. This rate can be increased in an air diffusion system by subjecting the culture to high shear and high pressure. A study of the effects of high...

Flow characteristics of constructed wetlands : tracer studies of the hydraulic regime

Creator:: Stairs, Darrin B.
Abstract:: Treatment efficiency in a constructed wetland is related in part to the amount of time that a wastewater remains in the system. Current design methods idealize the system as a plug flow reactor and use a "residence time" based solely on the volume of the cell and the flow rate....

Effect of plant surface area on organic carbon removal in wetlands

Creator:: Kuehn, Elaine Jinx
Abstract:: This study investigated the effect of plant surface area (plant density) on the efficiency of organic carbon removal in a bench-scale constructed wetland. Constructed wetlands are commonly assumed to be biofilm reactors in which organic carbon removal occurs primarily through sedimentation and aerobic degradation by attached microbial biofilms. In conventional...

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...

Startup and performance of a gas-permeable-membrane-supported (GPMS) biofilm system using a mixed culture of methylotrophs to degrade methylene chloride, chloroform, and carbon tetrachloride

Creator:: Ely, Roger L.
Abstract:: The methane monooxygenase (MMO) enzyme, used by methylotrophs to oxidize methane, has been shown to possess quite broad substrate specificity, being able to oxidize many organic compounds including n-alkanes, n-alkenes, ethers, and aromatic, alicyclic, and heterocyclic compounds. In this research, it was sought to determine whether a gas-permeable-membrane-supported (GPMS) biofilm...
