Secondary Treatment

Secondary treatment is designed to substantially degrade the biological content of wastewater. The majority of municipal plants treat the settled sewage liquor using aerobic biological processes. To be effective, the biota require both oxygen and food to live. The bacteria and protozoa consume biodegradable soluble organic contaminants (e.g. sugars, fats, organic short-chain carbon molecules, etc.) and bind much of the less soluble fractions into floc. Secondary treatment systems are classified as: fixed-film, and suspended-growth. Advanced treatment options include: Membrane Bio-Reactors (MBR’s), and Moving Bed Bio-Reactors (MBBR’s)
