A new type of biofilm reactor adapted to Brazilian conditions and using polyurethane foam to lower costs can reduce the amount of nitrogen compounds in wastewater by as much as 70%, according to an article in Environmental Technology. The researchers who conducted the study developed a mathematical model to analyze and predict the nitrogen removal mechanism. The biofilm comprised bacteria that converted nitrogen compounds into nitrogen gas, which is environmentally harmless.
