Before wastewater reaches recipient waters, nutrients must be removed in order to avoid eutrophication and large algal blooms, which may result in serious damage to animal and plant life. Robert Almstrand at the Depertment of Chemistry and Molecular Biology at the University of Gothenburg, Sweden, has shown in his thesis that better removal of nitrogen from wastewater can be achieved by providing the bacteria that purify the water with alternating high and low levels of nutrients.
