Abstract: The recovery of ethylenediaminetetraacetic acid (EDTA) from washing effluents is essential to reduce the cost of EDTA-enhanced soil washing and the production of wastewater. This study evaluated a recovery method, in which ...

Abstract: Einstein's bed load transport equation was modified for laminar overland flow under rainfall conditions. The modifications consisted of using a laminar velocity profile and a lift force calculated from the fluid drag force. ...

Abstract: The effects of the operating conditions, the initial concentrations of heavy metals in soils, and the competition among heavy metals during ethylenediaminetetraacetic acid (EDTA)-enhanced soil washing were extensively ...

Abstract: The effects of the operating conditions, the initial concentrations of marine diesel fuel (MDF) and the coexisting Pb in the soil, and the ethylene diamine tetra acetic salt (EDTA) in solution on MDF removal by sodium ...

Abstract: Secondary clarifiers are a vital component of the activated sludge process. Previous studies have showed that operation factors such as surface overflow rate (SOR) and solids loading rate have an essential impact on secondary ...

Abstract: Based on a problem decomposition strategy and a symbolic kinematic loop pattern matching technique, a new method for planar mechanism kinematic analysis has been uncovered. Since this approach ...

Abstract: Automatic mechanism sketching can be considered to be a computational approach for converting the graph representation of a mechanism into its skeleton diagram representation, subject to the ...

Abstract: This paper presents a design for a new tuned gyroscope framework consisting of a heavy rotor supported by a heli-flex suspension. Inherently free of 2ω drift-error, the gyro can be precisely ...

Abstract: In a paper-based paradigm, whether construction information is presented in structured or unstructured format is not a critical issue because human beings are good at processing both types of information. However, the ...
