  • RE: Reproducibility?

    This paper states the benefit of using hollow fiber form of membrane which has potential for "large scale" application, all the experiments were tested in single fiber module. Wondering about the reproducibility of experiments, seems no error bar for any of the permeation experiments.
    Also, there is a need to clarify the definition of reverse osmosis. It looks like a pressure driven reverse osmosis process when doing the separation tests of xylene. It is not convincing enough. If the experiments were run in forward osmosis mode with different composition of mixture, would the results follow as the normal water forward osmosis mode experiments?
