SBRs are also suited for sites that need minimal
operator attendance and that have a wide range of
inflow and/or organic loadings.
Industries with high BOD loadings, such as
chemical or food processing plants, will find SBRs
useful for treating wastewater. These systems are
also suitable for facilities requiring nitrification,
denitrification, and phosphorous removal. Most
significantly, SBRs are applicable for areas where
effluent requirements can change frequently and
become stricter, 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.
