  • The preparation characteristics of hydrogen permselective membranes for higher performance in nuclear hydrogen production

    The thermochemical water-splitting method has been proposed as a clean method for hydrogen production. The IS (iodine–sulphur) process is one of the thermochemical water-splitting processes. The silica membrane to apply in membrane reactor for the HI decomposition reaction improvement of the IS process was prepared by sol-gel and thermal CVD (chemical vapour deposition) methods. In the prepared ...

  • Dynamic Mathematical Modeling of Membrane Fouling in Submerged Membrane Bioreactors

    ABSTRACTA mathematical model is developed that accounts for internal fouling of membranes due to soluble microbial products during subcritical flux operation, and for supercritical flux fouling due to cake formation and compression.. The model takes into account the filtration effect generated by the cake. A set of differential equations is derived and solved numerically to obtain a description ...

  • Treating Industrial Water with Membrane Technology

    A variety of industries are finding that it makes sense to reevaluate the way they treat industrial process water, both to improve the quality of their products and increase the efficiency of their processes. Purification systems utilizing crossflow membrane filtration, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF) can be a good alternative to traditional filtration ...
