For a glucose-fed bio-hydrogen producing bioreactor, we have fitted the model parameters of a known model using experimental data obtained from a pilot laboratory-scale bioreactor. We use this fitted model to design an output-feedback controller based on the super-twisting algorithm, which uses only the on-line measurements of the hydrogen production rate and maximizes this variable by manipula...

The process characteristics of a pilot-scale trickling filter system were quantified by means of a measurement campaign with the use of off-gas analysis. A load shift experiment was conducted in which the influent load to the trickling filter system was suddenly decreased. To model the biodegradation in the filters, the model developed by Rauch et al. (1999) was used. This model was extended wi...

Membrane distillation is a process that utilizes differences in vapor pressure to permeate water through a macro-porous membrane and reject other non-volatile constituents present in the influent water. This review considers the fundamental heat and mass transfer processes in membrane distillation, recent advances in membrane technology, module configurations, and the applications and economics...

We define and analyze a goal-oriented procedure for model calibration in Computational Mechanics. In this procedure, priority is given in the updating to parameters which are the most influent to predict a given quantity of interest. The strategy uses the constitutive relation error framework as well as duality and adjoint techniques. The objective is thus to perform a partial model validation ...

The late 19th century was a golden period of the Brain Psychiatry, with its German movement and influent members, such as Wilhelm Griesinger (1817–1868), and Theodor Hermann Meynert (1833–1892), as seen in Fig 1, who was the most arduous defender of a strong organic basis for Psychiatry1. Griesinger asserted in his 1845 “Pathologie und Therapie der psychischen Krankheiten” the primacy of brain ...

Municipal leachate was treated in an experimental unit of constructed wetlands of subsurface flow type. The parameters studied were organics (BOD and COD), solids and heavy metals (Zn, Ni, Cu, Cr and Pb). Using two types of emergent plants of Scirpus globulosus and Eriocaulon sexangulare, more than 80% removal was achieved for all the parameters. E. sexangulare removed organics and heavy metals...

The present status of antimicrobial-resistant bacteria (AMRB) and antimicrobial-susceptible (AMSB) in hospital effluent, sewage treatment plant (STP) influent, STP secondary effluent (chlorination), (ozonation), river water were analyzed an urban Japan by a 2-year monitoring survey. results revealed the existence multiple AMRB grouped into six classes whose numbers at 19 to 2,800 CFU/mL, influe...

Assamra wastewater treatment plant (WWTP) is the largest facility in Jordan. Treated discharged into Zarqa River (ZR) and used to irrigate fodder vegetables. ZR also includes surface runoff, stormwater, raw illegally river. This study examined pharmaceutically active compounds (PhAC) water resources basin. Samples of WWTP influent effluent river from four sites along were collected. Concentrati...

Multicell constructed wetlands (MCWs) on lakeshores are a prospective treatment technique. However, the factors affecting nutrient removal performance of lakeshore MCWs at field scale unclear. This study chose field-scale MCW with highest mass efficiency (approximately 49,175.12 mg m−2 day−1) for total nitrogen in wet season to investigate response and microbial distribution seasonal shock nutr...
