as these systems have tremendous
flexibility to change treatment options. However,
part of the economic advantage of the SBR process
is lost when advanced treatment processes must be
added downstream since intermediate equalization
is normally required.
Oxidation ditches
Oxidation ditches are suitable for facilities that
require nutrient removal, have limitations due to the
nature of the site, or want a biological system that
saves energy with limited use of chemicals unless
required for further treatment. Oxidation ditch
technology can be used to treat any type of
wastewater that is responsive to aerobic
degradation. In addition, systems can be designed
for denitrification and phosphorous removal.
