Testing of leachate treatment plant


In these days the testing activities of the new leachate treatment plant serving the landfill area of ​​ Grotte San Giorgio district in the municipalities of Catania and Lentini (SR) have being carried out. The process consists of a first phase of ultrafiltration followed by three different stages of reverse osmosis. This technology guarantees the variation of the qualitative and quantitative characteristics of the incoming leachate and of the outgoing permeate, satisfying the most restrictive regulatory standards (tab.3 of Annex 5 to Part III of Legislative Decree 152/06). The pictures of the permeate samples obtained respectively from both the ultrafiltration phase and the first reverse osmosis stage are reported below.
