Leachate, which refers to dark-colored toxic wastewater generated from landfills, has
become an issue of environmental concern, posing a threat to soil, surface water, and …

Landfill leachate contains a large amount of organic matter and ammoniacal nitrogen. As
such, it has become a complex and difficult issue within the water treatment industry. The …

Bacillus methylotrophicus strain L7, exhibited efficient heterotrophic nitrification–aerobic

Rotating biological contactors (RBCs) for wastewater treatment began in the 1970s.
Removal of organic matter has been targeted within organic loading rates of up to 120 gm …

In this work, a pilot-scale low dissolved oxygen (DO) composite biological system (LDOCBS)
composed of an anoxic rotating biological contactor (RBC) and four aeration tanks with …

In order to solve nitrogen pollution in environmental water, two heterotrophic nitrifying and
aerobic denitrifying strains isolated from acid paddy soil were identified as Achromobacter …

The bacterial strain F6 was isolated from a biological aerated filter that is used for purifying
recirculating water in a marine aquaculture system and was identified as Marinobacter sp …

Landfill leachate comprises highly toxic and hazardous compounds posing adverse health
effects to the ecosystem and human populations. These leachates must be subjected to …

A 60 L membrane aerated biofilm reactor (MABR) was successfully employed to treat landfill
leachate, which contained very high concentrations of refractory chemical oxygen demand …
