Membrane bioreactors are advanced treatment technologies that, compared to conventional processes, expected reduce antibiotic resistance spread in the environment due their superior biomass retention. In this study, metagenomic sequencing was used assess response of microbial community and profile an aerobic membrane bioreactor (AeMBR) anaerobic (AnMBR) operated parallel, treating identical syn...

Winery wastewater (WWW) handling strategies often include co-treatment at municipal treatment plants (WWTPs). Despite this, definitive information regarding oxidation kinetics and process performance impacts due to is lacking. A combined Michaelis–Menten–University of Cape Town kinetic model has been found best describe the pH-inhibited aerobic biological WWW by heterotrophs in activated sludge...

one of the most important concerns in tehran municipal landfill is the production of leachate and its potential for water resources pollution, this study was undertaken to examine feasibility of biological and physico/chemical treating of high-strength landfill leachate that was collected from tehran municipal landfill. average cod of the leachate in aerobic submerged membrane bioreactor is 680...

Inhomogeneities in key cultivation variables (e.g., substrate and oxygen concentrations) have been shown to affect process metrics large-scale bioreactors. Being able understand these gradients is hence of interest from both an industrial academic perspective. One the main shortcomings current modelling approaches that volume change not considered. Volume increase a feature fed-batch fermentati...

This preliminary study was aimed at evaluating the feasibility to produce biopolymers (BP) from citrus wastewater by mixed microbial culture in an anaerobic/aerobic membrane bioreactor (A/O-MBR). The activated sludge of A/O-MBR successfully enriched microorganisms having a good capacity producing intracellular biopolymers. production BP found be about 0.55 mgCOD mgCOD−1 using pure acetate conce...

The effects of polyurethane sponge size and type on the performance of an up-flow sponge bioreactor were studied using different sponge cube sizes (1 x 1 x 1 cm, 2 x 2 x 2 cm and 3 x 3 x 3 cm) and types of sponge (S28-30/45R, S28-30/60R, S28-30/80R and S28-30/90R). The reactors were operated under anaerobic conditions in an early stage and an aerobic condition in a latter stage. The results ind...
