Ceramic membranes represent the most important innovation achieved by the research in nanotechnologies applied to water treatment.
In plants with ceramic membranes the purification process is characterised by two phases: the first is the oxidation phase where, in the presence of oxygen, the bacteria degrade the incoming wastewater.
During the second phase, separation occurs by filtering the water, deprived of the muddy particles, through microporous membrane modules (0.2 micron) submerged in the tank. This process replaces the traditional sedimentation process.
