Webregion, where flux-dependent high fouling rates can be observed. Critical and threshold fluxes were measured by adopting the pressure cycle protocol [25]. Once the critical and threshold flux values were obtained, this data was used as input for a batch membrane process optimization method developed previously by Stoller et al. [26–35]. 2. Web30 de ago. de 2013 · The obtained results are satisfactory, since many times the authors reported that without any pretreatment, that is, at values higher than 44000% mg L −1, almost instantaneous zero flux conditions are met.Moreover, the value of is confirmed by the author’s personal experience: the process can hold on approximately 96 h before …
