Solid Waste Webinar: Leachate Management and Treatment
August 9, 2022 @ 1:00 pm - 2:00 pm EDT
Leachate and other landfill-generated liquids (gas condensate and dewatering liquids) can be some of the most challenging industrial wastewaters to manage and treat. Typically, elevated organics and ammonia are the drivers for treatment selection. However, leachate is comprised of compounds from a combination of sources that need to be evaluated for permit- or performance-driven reasons. Less predominant or non-regulated leachate compounds need to be considered that may cause process inhibition or foul treatment processes. Effluent limitations on other non-biodegradable or persistent compounds may drive the need for alternative treatment methods. The very nature of leachate does not lend itself to conventional application of treatment methods to meet typical effluent limitations.
We will explore the different technologies employed solely or collectively in leachate treatment to remove solids, biodegradable organics, nutrients, oil & grease, VOCs, refractory and persistent compounds, metals, and dissolved inorganics. The discussion will include a breakdown of how each technology can be utilized and its limitations. Case studies will be presented on how simple and complex treatment process schemes have been employed to achieve the owner’s objectives.
