Simultaneous nitritation and p-nitrophenol removal using aerobic granular biomass in a continuous airlift reactor.
The chemical and petrochemical industries produce wastewaters containing ammonium and phenolic compounds. Biological treatment of these wastewaters could be problematic due to the possible inhibitory effects exerted by phenolic compounds. The feasibility of performing simultaneous nitritation and p-nitrophenol (PNP) biodegradation using a continuous aerobic granular reactor was evaluated. A nit...
متن کاملBiological removal of p-cresol, phenol, p-hydroxybenzoate and ammonium using a nitrifying continuous-flow reactor.
Phenolic compounds biodegradation and its effect on the nitrification process were studied. A continuous stirrer tank reactor was operated in four stages, and phenolic compounds were fed as sequential way. In the first stage, at loading rate of 220 mg NH(4)(+)-N/Ld, the consumption efficiency was of 91%, being the product, nitrate. After that, p-cresol was fed at 53 mg C/Ld, reaching removal ef...
متن کاملSequencing batch reactor (SBR) and sequencing batch airlift reactor (SBAR) with the formation of aerobic granules
This research examined novel configuration of SBAR in lab-scale for industrial wastewater treatment. To evaluate COD removal efficiency and granules formation of the novel reactor (R1), SBAR system (R2) was operated under similar conditions during the experimental period. R1 and R2 with working volume of 3.6 and 4.5 L were used to cultivate aerobic granules. Both reactors were operated for 4 hr...
متن کاملNon-Linear Data Reconciliation for a Partial Nitritation (SHARON) Reactor
This work demonstrates the usefulness of non-linear data reconciliation to evaluate available measurements and estimate unmeasured variables for a full-scale partial nitritation (SHARON) reactor for the treatment of wastewater with high ammonium concentrations. Despite a lack of measured data, the bilinear approach of formulating system constraints allowed to satisfy the requirements for data r...
متن کاملInfluence of biomass production and detachment forces on biofilm structures in a biofilm airlift suspension reactor
The influence of process conditions (substrate loading rate and detachment force) on the structure of biofilms grown on basalt particles in a Biofilm Airlift Suspension (BAS) reactor was studied. The structure of the biofilms (density, surface shape, and thickness) and microbial characteristics (biomass yield) were investigated at substrate loading rates of 5, 10, 15, and 20 kg COD/m3. day with...
