UU trials enhanced phosphorus removal at Grasmere

摘要

United Utilities is upgrading its phosphorus removal capability at a wastewater treatment plant in Grasmere, Cumbria, in a 12-month trial. The discharge of phosphorus - a nutrient that can stimulate the growth of algal blooms which reduce oxygen in rivers and lakes - is being more tightly restricted under the Water Framework Directive because of the negative impact it can have on aquatic life.
