Multi-Barrier Treatments

These treatment processes consist of several barriers to ensure sufficient reduction of the various materials that need to be controlled and to allow for normal variations in the performance of each barrier. As in all treatment processes, monitoring is important in order to check that the processes are working properly and efficiently. Membrane filtration, reverse osmosis, advanced oxidation, riverbank filtration, and constructed wetlands may be parts of a multi-barrier treatment process. Not all of the processes are needed in all situations.
