This study investigated the effect of chlorinating an anaerobic reactor effluent with a high dosage electroactivated water (EAW) and using breakpoint strategy. The resulting quality was evaluated based on resolutions Brazilian Environmental Council. Disinfection by-products (DBPs) formation measured as total trihalomethane (THM4), i.e. sum chloroform (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), bromoform (TBM), which are four major THM4 species. results for were 217, 171...
N2O-production was investigated during nitrogen removal using aerobic granular sludge (AGS) technology. A pilot sequencing batch reactor (SBR) with AGS achieved an effluent in accordance national discharge limits, although presented a nitrite accumulation rate of 95.79% no simultaneous nitrification-denitrification. N2O production 2.06 mg L-1 the anoxic phase, emission air pulses and aeration phase 1.6% loading rate. Batch tests from verified that at greatest COD/N ratio (1.55), (1.08...
The assessment of nitrous oxide (N2O) and carbon dioxide (CO2) emissions from wastewater treatment processes using aerobic granular biomass is still scarce most them deal with synthetic in well-controlled conditions. Also, the greenhouse gases footprint process has been poorly described despite a strong impact on climate change. This work quantified analyzed N2O CO2 emissions, as well efficiency pilot-scale sequencing batch reactor sludge (AGS) fed real domestic wastewater. operational...
As estimativas de redução das reservas minerais aumentaram a demanda atual por novas fontes fósforo. Paralelamente, tecnologias buscam formas eficientes remover esse nutriente do meio aquático devido sua interferência na qualidade dos recursos hídricos. Neste sentido, e englobando os conceitos economia circular aplicados às biorrefinarias em estações tratamento efluentes, este estudo propõe recuperação um biopolímero presente no lodo granular aeróbio (LGA). O ALE (alginate-like exopolymer),...
Aerobic granular sludge (AGS) is currently considered one of the most promising technologies for biological wastewater treatment. This fact mainly due to combined removal organic matter and nutrients in same reactor, eliminating secondary settlers, making it compact technology on market. However, there are several reports problems, including: (i) instability biomass; (ii) long start-up periods slow granule formation, especially when using sewage with a low concentration matter; (iii)...
