Microbial fuel cells (MFCs) with hydrophilic poly(vinyl alcohol) (PVA) separators showed higher Coulombic efficiencies (94%) and power densities (1220 mW m(-2)) than cells with porous glass fiber separators or reactors without a separator after 32 days of operation. These remarkable increases in both the coublomic efficiency and the power production of the microbial fuel cells were made possibl...

Themembrane separator is a key component in a liquid-electrolyte battery for electrically separating the cathode and the anode, meanwhile ensuring ionic transport between them. Besides these basic requirements, endowing the separator with specific beneficial functions is now being paid great attention because it provides an important alternative approach for the development of batteries, partic...

This study evaluated the separation efficiency and developed a pressure drop model for a multicyclone separator used for natural gas purification. The collection and grade efficiencies of a multicyclone separator with 15 single cyclone separators were evaluated at inlet velocities of 6–24 m/s and particle concentrations of 30–2000 mg/m at atmospheric pressure and room temperature. The experimen...

INTRODUCTION This study assessed the air exhaustion control of corrugated plate interceptor (CPI) oil separators in a refinery wastewater treatment plant for biodegradation of volatile organic compounds (VOCs) by deep activated sludge aeration systems. Three approaches were used to derive VOC emission factors: * (a) Calculating using the aeration rate and VOC gas-liquid equilibrium concentratio...
