Biosurfactant‐assisted recovery and remediation of hydrocarbons from oily sludge using a mobile aerated washing system

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The oil industry generates oily sludge, the accumulation of which poses a serious environmental problem. Conventional methods require high costs, specialized equipment, and qualified personnel. This waste can be treated using biosurfactants.

Enhanced Electro-Dewatering of Sludge Through Inorganic Coagulant Pre-Conditioning

Separations
Sludge electro-dewatering technology is an attractive dewatering technology, but its application is limited by high energy consumption and filter cloth clogging caused by the dissolution of extracellular polymeric substances (EPSs). Thus, the addition of

Experimental investigation of sludge dewatering for single- and double-drainage conditions with a vacuum negative pressure load at the bottom.

PLoS ONE, 2021
The moisture content of municipal sludge is relatively high, which increases the cost of sludge transportation and treatment. To reduce the volume of the sludge, sludge dewatering is needed.

Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

A Functional Flows Framework for the Terminal Great Salt Lake Basin: Can We Have Our Lake and Drink It Too?

River Research and Applications, EarlyView.
ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...
