The BCFS process (Biological-chemical phosphorus and nitrogen removal) has been developed to achieve low nutrient effluent concentrations at relatively low BOD/N and BOD/P ratio's in the influent.. In combination with optimal operating conditions for biological nitrogen removal, chemical precipitation of phosphorus is used to ensure compliance with effluent standards regarding phosphorus. For the stripping of phosphorus-rich water from the biological treatment an in-line stripping construction can be used.
