Biological phosphorus removal during high-rate, low-temperature, anaerobic digestion of wastewater [PDF]

Frontiers in Microbiology, 2016
We report, for the first time, extensive biologically-mediated phosphate removal from wastewater during high-rate anaerobic digestion (AD). A hybrid sludge bed/fixed-film (packed pumice stone) reactor was employed for low-temperature (12°C) anaerobic ...
