Case study of Shin-Oyama 0.3 MLD Leachate Treatment Plant

The Shin-Oyama Leachate Treatment Plant is one of the leachate treatment plants that exist in Yokkaichi City, Mie Prefecture to treat leachate generated from final disposal sites under the Mie Prefecture Environmental Conservation Agency. This leachate treatment facility was commissioned in 2012 based on IFAS technology and designed for the following parameters:
