Wastewater Treatment Plants Enhanced Nutrient Removal Upgrade

Sixty-seven major facilities have been targeted to be upgraded with enhanced nutrient removal (ENR) technologies to achieve annual average nutrient goals of wastewater effluent quality of Total Nitrogen (TN) at 3 mg/l and Total Phosphorus (TP) at 0.3 mg/l.

Upgrading the 67 major plants will allow for nutrient reductions of 7.5 million pounds of nitrogen per year and 0.26 million pounds of phosphorus below the year 2000 levels (roughly 1/3 of Maryland’s commitment under the Chesapeake Bay 2000 Agreement).
