Abstract: The behavior of two spheres settling in a low Reynolds' number region is described from the hydrodynamic equations developed by others. Even when they are not close enough to form a floe, neighboring particles increase ...

Abstract: On Cape Cod, eco-toilets could help mitigate an existing pollution problem, but observed adoption rates have been extremely low. A household survey was used to examine primarily nonmonetary factors affecting homeowners’ ...

Abstract: The dynamics of particle capture and head-loss development were studied in laboratory filters over extended periods. Particle-size distributions and pressures were measured above the sand media and at three depths. Conditions ...

Abstract: Sphere drag data from throughout the twentieth century are available in tabular form. However, much of the data arose from experiments in small diameter cylindrical vessels, where the results might have been influenced by ...

Abstract: A population balance model was developed to simulate simultaneous precipitation and flocculation during precipitative softening. Rate coefficients for nucleation, crystal growth, and flocculation were extracted from ...

Abstract: The goal of this research was to compare the pollutant removal effectiveness of biofiltration systems containing different media and plant species. A laboratory column study was conducted by using three media and two plant ...

Abstract: As regulatory limits for contaminants in air and water become increasingly stringent, interest in steam stripping to remove synthetic organic compounds (SOCs) from industrial waters has increased. To identify situations ...

Abstract: Municipal and industrial sewers may be localized sources of volatile organic compound (VOC) emissions to the ambient atmosphere. Previous studies of VOC emissions from sewers have focused on sewers with large diameters ...
