Comparative analysis of the bacterial diversity in a lab-scale moving bed biofilm reactor (MBBR) applied to treat urban wastewater under different operational conditions

Simultaneous nitrogen and carbon removal from wastewater at different operating conditions in a moving bed biofilm reactor (MBBR): Process modeling and optimization

“…Adverse environmental impacts and enactment of more stringent legislation force the wastewater producers to treat wastewater before discharging to the environment [1][2][3]. Ammonium and nitrate concentrations in water environment persuade eutrophication and deplete dissolved oxygen due to activity of the ammonia oxidizing bacteria [4][5][6][7]. Therefore, removal of such substances from wastewaters in order to reduce their harm to the environment is of very much importance.…”

Study of moving bed biofilm reactor in diethyl phthalate and diallyl phthalate removal from synthetic wastewater

“…(3), Eq. and slope of drawing linear graph, respectively.Second order substrate removal equation proposed byGrau (1975) is expressed in Eq (5). and by integrating and linearizing that equation, second order equation can be summarized as Eq.…”

Nitrogen removal in a moving bed membrane bioreactor for municipal sewage treatment: Community differentiation in attached biofilm and suspended biomass

“…Several studies have shown the influence of these variables on the removal of C and N, biofilm morphology and composition, as well as on the diversity of total Bacteria and nitrifying bacteria communities developed in the biofilm [35][36][37][38]. In reference to the influence of the CFR, previous studies [35,37] have confirmed that this is one of the main factors explaining the variations in diversity and composition of biofilm total bacteria community and biofilm nitrifying bacteria. According to Wang et al [36], an increase in CFR promotes the increase of particle-particle and particle-wall collisions, which made the biofilm denser and thinner.…”
