Parametric Analysis and Breakthrough Modeling of Phosphorus from Al-Oxide Filter Media
Publisher: American Society of Civil Engineers
Abstract: Adsorptive filtration is becoming a common unit operation/process following a primary unit operation such as volumetric clarification of urban drainage flows and particulate matter. In this study, axial columns packed with ...
Parametric Evaluation of Batch Equilibria for Storm-Water Phosphorus Adsorption on Aluminum Oxide Media
Publisher: American Society of Civil Engineers
Abstract: Elevated and variable aqueous and granulometric concentrations of phosphate species (P) are commonly observed in urban rainfall runoff. Though physical operations such as sedimentation can potentially separate particulate ...
A Dynamic Model of an Electropneumatic Valve Actuator for Internal Combustion Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a detailed model of a novel electropneumatic valve actuator for both engine intake and exhaust valves. The valve actuator’s main function is to provide variable valve timing ...
Transport and Distribution of Particulate Matter Phosphorus Fractions in Rainfall-Runoff from Roadway Source Areas
Publisher: American Society of Civil Engineers
Abstract: During runoff transport, phosphorus (P) partitions between dissolved and particulate matter (PM) phases. PM-based P distributes across the particle-size distribution (PSD). This study investigates the transport and ...
Orthophosphate Adsorption Equilibrium and Breakthrough on Filtration Media for Storm-Water Runoff Treatment
Publisher: American Society of Civil Engineers
Abstract: Total phosphorus (TP) in storm-water runoff is a common regulatory target for maintaining the quality of receiving surface water. Previous storm-water treatment studies show that it is difficult to consistently achieve TP ...
Design of Three-Phalange Underactuated End Tool for the Chinese Space Station
Publisher: American Society of Civil Engineers
Abstract: Creating an effective terminal operation tool for in-orbit space station services is challenging, especially when dealing with limited spaces and intricate manipulations. Debate has long surrounded the use of anthropomorphic ...
