Simple Model for Ocean Outfall Plumes
We have shown that a power law model provides a simple technique for predicting the dilution as a function of depth, for depths characteristic of most outfall systems. In particular, we...

Removal of Cadmium (II) by Activated Carbon Adsorption
The adsorption of cadmium (II) from a dilute aqueous solution onto an activated carbon surface is investigated. The type and dose of activated carbon, the total concentration of cadmium...

Ozonation of Dilute, Low-Temperature Wastewater

Mean Behavior of Buoyant Jets in a Crossflow
A general theory to predict time-average trajectories and dilutions for turbulent buoyant jets in a crossflow is presented. The flow is analyzed by presenting simplified descriptions of...

Wastewater Disposal by Submerged Manifolds
Jet mixing from submerged manifolds for wastewater disposal has been studied by means of hydraulic model experiments. The experimental results show that the dilution and flow pattern of...

Population Balance Use in Dilute Impurity Problems
The application of population balance and kinetic analysis to problems concerning removal of dilute amounts of impurities from liquids is demonstrated. The technique is applied to data...

Hydraulic Collection and Disposal of Refuse
A concept for residential refuse management is examined that calls for individual household refuse grinders, dilute slurry transport of ground refuse in the existing sanitary sewer system,...

Role of Nitrogen in Activated Sludge Process
Study of the effect of nitrogen limitation on metabolic activities of activated sludge has been conducted by using a completely mixed continuous flow bench-scale activated sludge unit....

Nutrient Transformations in Mass Cultures of Marine Algae
Two mass cultures of marine algae were maintained for 24 continuous weeks on mixtures of secondarily treated wastewater and seawater. Nitrogen removal and algal growth were related to...

Use of Jet Pumps in Marine Waste Disposal
The prime objective of a marine waste disposal installation is to maximize the physical dilution of wastewater with seawater. Very often the formation of a submerged plume is desirable....

Enhanced Dispersion in Drag Reducing Open Channel Flow
Results are presented concerning the effect of high polymer drag reducing additives on turbulent dispersion in open channel flow. Theoretical analysis shows that the dispersion coefficient...

Relative Diffusion in Nonisotropic Turbulence
Based on knowledge of those turbulent water-flow conditions, which establish the minimum rate of turbulent surface diffusion, a simple relation is derived for the estimation of the rate...

Prediction of Mixing Lengths for River Flow Gaging
An analytical solution of the diffusion equation is used to determine criteria for use in river flow gaging by the dilution method. The method advanced in this paper allows the mixing...

Coagulation of Iron Oxide with Alum
Coagulation of dilute iron-oxide suspensions with alum has been studied at different pH values and coagulant concentrations. Measurements of pH, mobility, and particle concentrations in...

Dilution of Buoyant Two-Dimensional Surface Discharges
The flow of heated water from an open channel into a reservoir containing colder and essentially stagnant water has been studied in a laboratory flume. The basic mechanisms which produce...

Radioisotopes and Turbine Flow Measurement
Radioisotope techniques and equipment were developed at program completion to measure flow rates with a 2 σ error estimated to be ± 1.5%. In the five phase program, studies were made of...

Model Study of Dense Jet in Flowing Fluid
Investigations were conducted in a 1:20-scale model to determine the geometry and mixing characteristics of a dense jet discharged vertically into a uniform cross-current. The resulting...

Spread And Dilution Of Three-Dimensional Rectilinear Heated Water Surface Jets

Design of Browns Ferry Chimney
