A FRESH ENGINEERING EVALUATION OF LEACHATE TREATMENT OPTIONS
Abstract:Millennium Science & Engineering Inc. and their UK associate MSE Ltd., conducted a feasibility study on behalf of a UK waste management company to examine and help define:
Site water balance for leachate generation quantities and site leachate quality
Review of treatment options and initial definition of a suitable option with order of magnitude costs
Commissioning of Pilot Plant and operation of a full-scale treatment trial
The Hydrologic Evaluation of Landfill Practices (HELP) model was used to determine the water balance for the site. A review was conducted of the typical leachate treatment methodologies and a selection analysis was undertaken. The methodology appropriate from technological and commercial grounds was determined to be a moving bed biological reactor (MBBR).
The subsequent pilot trial had to be undertaken at an alternative site, one with a significantly different leachate quality, containing a much higher concentration of non-biodegradable COD. Despite the change in leachate characteristics and quality, the MBBR technology treated the biologically degradable COD to the required concentration.
