Nutrient Removal is Topic at New Hampshire and Maine Conferences

New Hampshire Joint Water and Watershed Conference

The 2009 New Hampshire Joint Water and Watershed Conference was recently held in Concord. The two day event, 2020 Vision, was designed to address environmental topics related to lakes, rivers, groundwater, and watersheds throughout the state of New Hampshire. Wright-Pierce engineers were among the invited presenters.

Wastewater Engineers Bill Brown, P.E., and Pete Atherton, PE, addressed the issue of nutrient removal in their presentation, "Nitrogen - The 21st Century Coastal Watershed Challenge." They discussed the various chemical, biological and secondary treatment technologies and related filtration technologies for addressing high nitrogen levels from effluent streams into watershed regions along the New Hampshire coast. The presentation also addressed the phosphorus levels from inland tributary rivers which eventually end up in our watersheds.

Bill Brown, P.E. also presented at the 2009 winter conference for the Maine Rural Water Association. His presentation "Wastewater Nutrient Removal - An overview of phosphorus and nitrogen removal strategies" outlined nutrient criteria for phosphorus and nitrogen and discussed removal strategies using Wright-Pierce projects in Jaffrey, NH; Smithfiled, RI; Sanford, ME and Falmouth, MA as case studies.
