Biological Nutrient Removal Processes
Historical Context of Phosphorus Removal • In 1960’s and 1970’s several plants reported removal of phosphorus above 80 percent • What they had in common: – Plug flow or compartmentalized aeration tank – Inadequate aeration at head of aeration tank provided low D.O. – High dissolved oxygen after low D.O. section
