The current study investigated the performance of a moving bed biofilm reactor (MBBR), when adding 3D-printed biocarriers fabricated with 13X and bentonite (MBBR 3D), using K1 commercial K1) not at all (control MBBR). For evaluation MBBR efficiency, various physicochemical parameters were measured, while extracted from was evaluated. findings suggest that there is an optimal biodegradation orga...

In this study, we designed a microbial electrochemical fluidized bed reactor (ME-FBR), with an electroconductive anodic bed made of activated carbon particles for treating a brewery wastewater. Under a batch operating mode, acetate and propionate consumption rates were 13-fold and 2.4-fold higher, respectively, when the fluidized anode was polarized (0.2 V) with respect to open circuit conditio...

Two labscale aerobic moving bed biofilm reactor (MBBR) systems, with a different type of biocarrier in each (K3 and Mutag BioChip), were operated parallel for the treatment real saline bilge water. During operation, stress conditions applied order to evaluate performance systems: organic/hydraulic load shock (chemical oxygen demand (COD): 9 g L−1; hydraulic retention time (HRT): 48–72 h) salini...

The goal of this study is to investigate the performance of a pilot-scale trickle-bed air biofilter (TBAB) for treating volatile organic compounds (VOCs) emitted from a manufacturer of optoelectronic apparatus. Different empty-bed residence times (EBRTs) of 90, 60, 30, 20 and 15 s were evaluated. Greater than 90% VOC removal efficiencies were achieved at EBRTs longer than 20 s. EBRTs of 20-30s ...

Anaerobic digestion for biomethane production is an important tool regarding sustainable energy production. The objective of this study was to investigate the effects substrate composition and operating parameters on during anaerobic digestion, focusing use flotates slaughterhouse waste as substrates with a high organic content. A novelty here moving bed biofilm reactor (MBBR) circulation pump ...

In a previous work, a hybrid system consisting of an advanced oxidation process (AOP) named Photo-Fenton (Ph-F) and a fixed bed biological treatment operating as a sequencing batch biofilm reactor (SBBR) was started-up and optimized to treat 200 mg ·L of 4-chlorophenol (4-CP) as a model compound. In this work, studies of reactor stability and control as well as microbial population determinatio...

A novel process configuration was designed to increase biofilm growth in tertiary moving bed reactors (MBBRs) by providing additional substrate from primary treated wastewater a sidestream reactor under different redox conditions order improve micropollutant removal MBBRs with low availability. This recirculating MBBR operated on pilot scale for 13 months, and systematic seen the biomass concen...

Natural or engineered microbial populations often show variations over time. These variations may be due to environmental fluctuations or intrinsic factors. Thus, studying the dynamics of microbial diversity for different communities living in a spatially homogeneous landscape is of interest. As a model ecosystem, nitrifying biofilm communities were grown in a two litre inverse turbulent bed re...
