Removal of crystal violet from wastewater using synthesized graphene quantum dots as adsorbents: kinetic approach
Aromatic triarylmethane dyes residues cause serious water pollution in environment. Adsorbents, such as graphene oxide (GO), have great potential for using them for removal of dyes such as crystal violet (CV) ...

The selective salinity and hydrazine parameters for the start-up of non-anammox-specific biomass SBR
The presence of ammonium (NH4+) in wastewater above the permissible limits leads to undesirable ecological impact and public health concerns. In this study, the anaerobic ammonium oxidizing (anammox) bacteria-med...

Methane Production in a Temperate Freshwater Lake during an Intense Cyanobacterial Bloom
Seasonal cyanobacterial blooms have a negative impact on freshwater ecosystems. The role of cyanobacteria in methane production and their relationship with methanogenic archaea are not yet well understood. The...

Methane Cycle in a Littoral Site of a Temperate Freshwater Lake
Eutrophication of lakes results in the intensification of anaerobic processes, including methanogenesis, and therefore in enhanced emission of methane. A littoral area with its variable oxygen regime is the fi...

Enhancement of anoxic phosphorus uptake of denitrifying phosphorus removal process by biomass adaption
Economical and efficient phosphorus (PO4-P) removal technologies with low oxygen and organic carbon demand are needed to avoid eutrophication and reduce wastewater treatment costs. A sequencing batch reactor (SBR...

Inoculum-free start-up of biofilm- and sludge-based deammonification systems in pilot scale
Undiluted reject water from the dewatering of anaerobic sludge with an average total nitrogen content of 718 ± 117 mg L−1 (n = 63) was used to start-up autotrophic nitrogen removal in three different pilot-scale...

Ameliorating nitrite inhibition in a low-temperature nitritation–anammox MBBR using bacterial intermediate nitric oxide
The long-term sustainability of an anaerobic ammonium oxidation (anammox) process in a moving bed biofilm reactor (MBBR) treating highly concentrated (mean of 740 mg NH4 +-N L−1) wastewate...
