Details

The turnover of the nitrogenous components of landfilled refuse was studied and reviewed in a former Department of the Environment-funded study, ‘Nitrogen Balances in Landfills,’ available as two publications in the CWM series. In the light of these laboratory studies, suggestions were made of a possible method for managing landfill sites likely to lead to the rapid and permanent reduction of leachate ammonia. This involved a strategy of ammonia treatment and recirculation of nitrified leachate. The aim of this research was to use laboratory studies to formulate a leachate pre-treatment and recycling strategy, and to demonstrate, at the Auchencarroch test cell facility, the efficacy of this in reducing leachate ammonia concentrations and accelerating site stabilisation.
