The Post-Treatment phase (Secondary treatment):The Post-Treatment phase (Secondary treatment):The water leaves the biological purification phase into the secondary treatment The water leaves the biological purification phase into the secondary treatment chamber called the Post-Clarifier Tank. This phase serves for the separation of the chamber called the Post-Clarifier Tank. This phase serves for the separation of the biologically cleaned water from the surplus biomass. The Post-Clarifier Tank has a biologically cleaned water from the surplus biomass.
