Denitrification/dephosphorization process
Dephosphorization and Denitrification Process
Seshin Clean’s dephosphorization and denitrification is a one-step higher level process that minimizes operating costs by reducing electricity costs and carbon sources as this process generates ANAMOX and SURAMOX reactions along with the existing nitrification and denitrification simultaneously.
