Proposed Models of Colloid-Facilitated Transport for Total-System Performance Assessment
Sorption of Radionuclides at Tracer Level on Mineral Colloids
Detachment of Humics-Coated Colloids from Fluidized Beds
Colloid-Facilitated Transport of Hydrophobic Compounds in Sandy Soils
Colloidal Fouling of Reverse Osmosis Membranes
Experiments on the fouling of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Fouling was significant at high ionic strengths,...
Size Characteristics of Debris Flow Deposition
The size distribution of debris flow deposition is extremely wide which may contain nearly all particles from clay and colloid to boulder. Particle size and composition have very important...
Movement of Colloids Under Hydraulic Gradients
A model was developed for analyzing the movement of colloidal clay particles in laboratory soil columns. The physical mechanisms of detachment of particles from the soil matrix, their...
NCASI Experiment Related to Validation of Equilibrium Partitioning (EP) Theory
A review of NCASI's technical studies related to evaluating equilibrium partitioning (EP) theory as it is commonly applied in regulatory setting is presented. Although interim results...
Modelling Colloidal Transport of Radionuclides Through Porous Media
General acknowledgement of the potential role of colloids in enhancing radionuclide transport has prompted the preliminary development of a mechanistic colloid transport model as part...
Are Colloids Important for Transport Rate Assessment of Radionuclides? A Microscopic Modeling Approach
Understanding the transport phenomena of radionuclides migrating through weakly-permeable rocks forms an essential part of far-field safety assessment studies. Colloidal matter can be...
Quantitative Comparison Between Colloidal and Solute Transport
Radiocolloid Transport in Saturated and Unsaturated Fractures
Studies have shown that radionuclides and toxic materials can attach to colloidal particles in groundwater or are themselves colloids. Since these contaminated particles can migrate several...
Characteristics of Colloids in Landfill Leachate
Leachate was collected from a municipal landfill which has been closed for about 15 years. The sample was collected (under a N2 atmosphere) only...
