About Nereda® Wastewater Treatment Works in Kendal, UK
Kendal is a market town in the South Lakeland District of Cumbria, England, which lies in the valley of the River Kent.
Population increases meant that Kendal WWTP was required to treat a population equivalent of 103,000. This meant that United Utilities (UU) needed a solution to improve its wastewater treatment quality at Kendal WWTP, to enable it to achieve regulatory compliance, while reducing its operational cost.
UU selected LiMA to deliver the project and work closely with Nereda technology provider Royal HaskoningDHV. Kendal WWTP was UU’s first full-scale application of Nereda technology, following an intensive review period. The application of the Nereda technology is part of its drive to reduce operational costs across its wastewater operations.
Kendal WWTP was operational and already achieving exceptional performance prior to UU’s March 2019 compliance date. Nereda offers a number of advantages over conventional activated sludge, due to the nature of the granules. Contrary to conventional processes, bacteria concentrate into a compact granular structure with excellent settling characteristics. The compact structure also leads to the formation of different zones which provides the optimum conditions for simultaneous nitrification and denitrification as well biological phosphorus removal.
