background: leachatecontaining high levels of organic pollution with ammonia, halogenatedhydrocarbons, heavy metals and inorganic salts. among the various methods fortreating leachate, has been developed membrane processes so that a morebiological process of membrane processes is used for separation of solid -liquid. the aimof this study was to evaluate the efficiency of membrane bioreactor eff...

In this study, a lab-scale fixed-film bio-media process was developed and operated to evaluate nitrogen removal from domestic sewage treatment plants. For removal, the applied in series with anaerobic, anoxic, aerobic units three separate reactors that were continuously at same loading rates hydraulic retention time. A biofilm separation bioreactor for on-site wastewater employed synthetic fibe...

in this paper, the fuzzy system has been used for fault detection and diagnosis of a yeast fermentation bioreactor based on measurements corrupted by noise. in one case, parameters of membership functions are selected in a conventional manner. in another case, using certainty factors between normal and faulty conditions the optimal values of these parameters have been obtained through the genet...

Mesenchymal stromal cell (MSC)-derived products, such as trophic factors (MTFs), have anti-inflammatory properties that make them attractive for cell-free treatment. Three-dimensional (3D) culture can enhance these properties, and large-scale expansion using a bioreactor reduce manufacturing costs. Three lots of MTFs were obtained from umbilical cord MSCs produced by either monolayer (Monol MTF...

Heavy metals are necessary at low concentration for biological activity, but they often toxic microorganisms high concentrations. Amplicon sequencing of 16S rRNA and 18S was used to investigate changes in the bacterial microeukaryotic communities an activated sludge bioreactor incrementally contaminated with nickel (Ni), copper (Cu), zinc (Zn) IC 50 value ranging from 0% 100%, as previously det...

This data article shows how the recombinant Chinese Hamster Ovary (CHO) cells are located in the interstices of the matrix fibers of a CellTank bioreactor after completion of a perfusion culture, supporting the article entitled "Very high cell density perfusion of CHO cells anchored in a non-woven matrix-based bioreactor" by Zhang et al. [1]. It provides a visualization of the cell distribution...
