Recirculating aquaculture systems (RAS) are operated as outdoor or indoor systems. Due to
the intensive mode of fish production in many of these systems, waste treatment within the …

Wetland assessment tools are being developed and employed in wetland monitoring and
conservation based on physical, chemical and biological characterization. In wetland …

Nitrification activities and microbial populations of ammonium oxidizing bacteria (AOB) and
nitrite oxidizing bacteria (NOB) were investigated in 10 full-scale biological nutrient removal …

Landfill disposal has been considered as a very economically viable management practice
for municipal solid waste in mainland China. However, insufficient knowledge of the …

Heavy metals contamination in sediment poses serious threats to bacterial communities that
play critical roles in sediment biogeochemical processes. However, the physicochemical …

Ammonia-oxidizing organisms play an important role in wetland water purification and
nitrogen cycling. We determined soil nitrification rates and investigated the seasonal and …

This study investigates the effects of temperature on ammonia oxidizing bacteria activity in a
partial nitritation (PN) sequencing batch reactor. Stable PN was achieved in a 250L SBR …

With annual increases in the generation and use of saline wastewater, the need to avoid
environmental problems such as eutrophication is critical. A previous study identified ways …

Background Biological WWTPs must be functionally stable to continuously and steadily
remove contaminants which rely upon the activity of complex microbial communities …

Nitrogen removal in wastewater treatment systems such as constructed wetlands mainly
relies on autotrophic nitrification followed by heterotrophic denitrification. Two major …
