BACKGROUND In order to meet the International Maritime Organization (IMO) objectives, the main purpose of this study was using the cheap and practical wastewater treatment system for low-strength bilge water of Caspian Sea ships; therefore, the low-strength bilge water of the Caspian Sea ships has been treated by up-flow anaerobic sludge fixed film (UASFF) reactor at the ambient temperature. ...

In this study, a Computational Fluid Dynamics (CFD) model was developed to evaluate ultraviolet disinfection applesauce reactor. To simulate UV reactors, three sets of equations, including hydrodynamics, radiation and species mass conservation were solved simultaneously. The Realizable k-e turbulence model and the discrete ordinate method were used to find the UV radiation profile through the r...

The aim of the present study was to design a solar reactor and analyze its performance for removal of methyl violet dye (MV) from water with titanium dioxide as the photocatalyst. The solar reactor was made up of a flat-plate colorless glass of dimensions 1000 x 750 x 4 mm. The base of the reactor was made of aluminum. Various operating parameters were studied to investigate the behavior of the...

A rotary reactor and a fluidized bed reactor (both laboratory-scale and operated in batch mode) are used for the treatment of granulates containing SSA and CaCl ) and treating this mixture (possible after granulation) in a rotary kiln at 1000±100°C leads to the formation of volatile heavy metal compounds which evaporate and to Pphases with a high bio-availability. Due to economical and ecologic...

A multi-institutional team led by McDonnell Douglas has undertaken a study which includes the design of both a laser-driven (KrF) and heavy-ion-driven (HI) commercial fusion power reactor. A more general paper describing the overall reactor designs can be found in this proceedings [l]. The cavity, which is the subject of this paper, involves the components surrounding the pellet reaction chambe...
