  • Immobilization of horseradish peroxidase on silane-modified ceramics and their properties: potential for oily wastewater treatment

    Horseradish peroxidase (HRP) is proved being effective in eliminating oil from aqueous solutions, but the elimination is expensive because free HRP can not be reused. In present work, HRP was successfully immobilized on cordierite porous ceramics support with a novel method of N-β-aminoethyl-γ-aminopropyl-trimethoxysilane modification and glutaraldehyde activation. Under the optimized immobilized ...

  • Investigation of surface and filtration properties of TiO2 coated ultrafiltration polyacrylonitrile membranes

    In the present work, the surface and filtration properties of TiO2 coated polyacrylonitrile ultrafiltration membranes were investigated. The membranes were coated using the physical deposition method. The appropriate TiO2 coverage proved to be 0.3 mg/cm2, which formed a hydrophilic cake layer on the membrane surface. The cleanability without chemicals and the retention of the ...

  • Monitoring Hydrocarbons in Bilge Water

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as garbage may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited ...

  • The flocculation mechanism and treatment of oily wastewater by flocculation

    In the present study, the performance of compound flocculants composed of different concentrations of polyaluminum chloride (PAC) and cationic polyacrylamide (CPAM), the influencing mechanism of the flocculation process and the effects of temperature, settling time, and speed and time of stirring were investigated. The results show that the poor water quality with high concentrations of oil, ...
