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...
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...
Effects of Flocculation on Particle Transport
On the basis of previous experimental and theoretical work on flocculation rates and the settling speeds of flocs, an accurate and computationally efficient model of the aggregation and...
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...
Fractal Dimension of Aggregated Sediments
Cohesive sediment dynamics in estuarine systems are strongly affected by particle aggregation and flocculation. These processes are mainly controlled by the Brownian motion, flow turbulence...
Modifications for Extending the Treatment Capacity
An approach for minimizing influences of increasing raw wastewater flow rates is proposed, based on modifying existing primary sedimentation units, by transforming them to flocculation...
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...
Upgrading Water Filtration Plants
Adding or improving mixing, flocculation, and sedimentation devices, and changing filter media can significantly increase water filtration plant capacity. Water quality can often be improved...
