Effect of anionic and nonionic surfactants on the biodegradation of solubilized n-decane
Developing an improved understanding of enhanced biodegradation is of great importance in remediation of contaminated soils and aquifers and in cleanup of oil spills. The effect of several nonionic and anionic surfactants ...
Formation and morphology of colloidal deposits in porous media
The effects of physical parameters such as fluid velocity, particle size and influent particle concentration on the morphology of colloidal deposits, removal efficiency and head loss development in porous media are ...
Laboratory development of the surfactant/foam process for aquifer remediation
The research presented was used to develop the surfactant/foam process for aquifer remediation. The surfactant/foam method was designed to address the problem of removing dense non-aqueous phase liquids (DNAPLs) spread ...
Investigation of membrane filtration in a rotating disk geometry: Use of computational fluid dynamics and laboratory evaluation
The feasibility, fluid dynamics and particle transport mechanics of rotary membrane filtration were investigated. The hypothesis tested was that, by rotating a disk membrane filter, a significant back-transport of suspended ...
Simulation of viscous fingering during miscible displacement in nonuniform porous media
Numerical simulation is used to study the effect of different factors on unstable miscible displacement and to clarify the mechanisms of finger growth and interaction. The two-dimensional equations of miscible displacement ...
Laminar fluid flow, particle transport and permeate flux behavior in crossflow membrane filters
Similarity solutions for axial and lateral velocity profiles, pressure gradients and wall skin friction are derived for the laminar, isothermal single phase flow of incompressible fluids in channels having porous boundaries. ...
