Description:
This report discusses a survey of phosphorus treatment approaches and accomplishments for all lower Great Lakes basin plants with flows greater than 1 mgd; field operation monitoring studies to evaluate the performance of four municipal treatment plants practicing phosphorus removal, including a determination of the bioavailability of the wastewater phosphours; and an analysis of costs at each of four plants monitored, including incremental costs to achieve a 0.5 mg/l standard. Of the 229 plants in this survey, 52 percent are achieving an effluent total phosphorus concentration of 1.0 mg/l, while only 8.3 percent (19 plants) are meeting a 0.5 mg/l standard.
