Advanced Leachate Treatment with Membrane Bio- logy and Nanofiltration-Operating Results from the Luneburg Central Dump

摘要

The leachate from the central dump at Luneburg is treated by a combination of membrane biology, nanofiltration, and ad- sorptive treatment of concentrate so that it can be directly discharged afterwards. While leachates with low pollution loads can be treated at Low costs with the biology plus activated carbon adsorption Process and are then ready for direct discharge, the incor- Poration of nanofiltration also allows the treatment of waste- Waters with higher pollution loads that must meet stricter Treatment standards.
