Biogenic Sediment Stabilization

3D Numerical Modeling of Cohesive Sediments

The Role of Macroflocs in Estuarine Sediment Dynamics and its Numerical Modeling

Automatic Control of Flocculation Processes
A control system for flocculation, used in water and wastewater treatment operations is being developed. The approach is based on detailed particle size distribution measurements of influent...

Studies on Herbal Desalination
India has a rich background traditional technologies. Varahamihira, an omni talented scientist of A.D 505–587 in his treatise entitled Brihatsamhita, suggested the use of five herbs for...

Application of an Optical Monitor in Automatic Control of Coagulation Dosing in Water Treatment Operations
The feasibility of applying an optical monitor in the automatic control of coagulation was assessed in this study. Prior to simulation testing, a series of batch tests was performed to...

Effect of Mixing on Flocculation Kinetics of Kaolin Clay Suspension at Cold Temperature Using Fe(III) Coagulant

Flocculation Kinetics Using Fe(III) Coagulant to Coagulate Kaolin Clay in Water: Effects of Temperature
Flocculation kinetics using ferric nitrate as a coagulant to coagulate kaolin clay in water was examined using several experimental factors. Both the particle size distribution data obtained...

Flocculation Techniques Used for Dredging Operations

Polyacrylamide Decreases Furrow Erosion
Erosion from furrow irrigated land is a serious problem in southern Idaho and several other areas. Polyacrylamide, a very long chain polymer, increases aggregate stability and flocculates...

Determining Velocity Gradient in a Flocculation Basin—A Case Study

Evaluation of THM-Formation Potential from Pilot Processes

Mine Tailings, Dispersants, and Flocculants

Development of an Automated Harbor Shoaling Monitor: Part I—Laboratory Testing

Direct Filtration of High Turbidity Water Using Contact Flocculation
It is shown that the system of bed contact flocculation followed by standard dual media filters provides a viable alternative to both conventional as well as direct filtration, particularly...

Aggregation and Consolidation of Phosphatic Clays
The consolidation behavior of aggregated phosphatic clays has been investigated using a bench scale centrifuge. It was determined that aggregation of the clays with phosphogypsum, a waste...

Particle Sizes in Flocculation and Sedimentation: Models and Experiments
D. F. Lawler et al. developed a model for flocculation, sedimentation, and filtration and predicted the effects of particle size distribution and concentration of the influent in water...

Innovative Engineering Completes Dredge Spoil Disposal Facility
A large dredge spoil facility was completed for the Fort McHenry Tunnel that received 3.5 million cu yds of dredged material, and was constructed so that it could be converted into a port...

Systems for Reducing Sedimentation in Berthing Facilities
Five systems are described which can be used to reduce sedimentation in harbor berthing areas. These systems, which are alternatives to conventional dredging, are based on either the resuspension...
