Every Challenge Has a Backstory
A large waste service provider in North America runs a landfill in the northeast that sends pretreated water to a city wastewater treatment plant before discharge into a local river. Due to a planned landfill expansion to support regional community and disposal needs, the waste service provider needed to upgrade its treatment system to expand its leachate treatment capacity from 80,000 to 300,000 gallons per day.
In addition, as more treatment municipalities are working to control the release of disinfection byproducts to help protect the environment, upgrading from chlorine to ultraviolet (UV) disinfection has become a preferred practice. As the city recently made this upgrade, the service provider also needed to improve UV transmittance of its leachate to mitigate impacts on the city’s new wastewater disinfection capabilities and ultimately improve the quality of water discharged to the river with respect to nitrogen-based nutrients.
