Secondary Treatment


Wastewater secondary treatment

Secondary treatments work generally with biological process (both aerobic and anaerobic) and they are installed downstream a primary treatment that can be mechanical or both mechanical and biological (usually anaerobic). They remove dissolved organic matter. This is achieved by microbes that use for their own growth and reproduction organic matter, converting into carbon dioxide, water, and energy. Most of the pollutions (eg. suspended solids and BOD) can be removed by a wastewater plants composed by a primary and secondary treatment units.
Secondary treatment technologies include all forms of treatment which use biological activity to break down organic matter.
