A key step toward energy-positive sewage treatment is the development of mainstream partial nitritation/anammox, a nitrogen removal technology where aerobic ammonium-oxidizing bacteria (AerAOB) are desired, while nitrite-oxidizing (NOB) not. To suppress NOB, novel return-sludge was investigated. Single and combined effects sulfide (0-600 mg S L-1), anaerobic starvation (0-8 days), free ammonia (FA) shock (30 FA-N L-1 for 1 h) were tested immediate long-term recovery. AerAOB NOB inhibited...
Abstract The development of carbon dioxide removal methods, coupled with decreased CO 2 emissions, is fundamental to achieving the targets outlined in Paris Agreement limiting global warming 1.5 °C. Here we are investigating importance organic feedstock support silicate mineral weathering small-scale flow through bioreactors and subsequent sequestration. Here, combine two bacteria fungi, widely reported for their potential, simple (columns) consisting forsterite available, cheap sources...
<ns3:p>Background The optimization of enhanced mineral weathering as a carbon dioxide removal technology requires comprehensive understanding what drives weathering. These drivers can be abiotic and biotic interact with each other. Therefore, in this study, an extensive 8-week column experiment was set up to investigate 29 potential simultaneously. Methods setup included various combinations types surface areas, irrigation settings, biochar organic amendments, along biota products such...
Nitrite oxidizing bacteria (NOB) and nitrous oxide (N2O) hinder the development of mainstream partial nitritation/anammox. To overcome these, endogenous free ammonia (FA) acid (FNA), which can be produced in sidestream, were used for return-sludge treatment two integrated-film activated sludge reactors containing biomass flocs on carriers. The repeated exposure from one reactor to FA shocks had a limited impact NOB suppression but inhibited anammox (AnAOB). In other reactor, FNA separated...
Enhanced weathering (EW) is an emerging carbon dioxide (CO2) removal technology that can contribute to climate change mitigation. This relies on accelerating the natural process of mineral in soils by manipulating abiotic variables govern this process, particular grain size and exposure acids dissolved water. EW mainly aims at reducing atmospheric CO2 concentrations enhancing inorganic sequestration. Until now, knowledge has been gained through experiments focused known for stimulating...
Unique pilot design and innovative control strategies enabled mainstream nitrogen removal with a low COD to N ratio at both summer winter conditions.
