Flexible A2/O and 5 Stage BardenphoProcess

•

• The process has the following operational flexibilities:•

• It can work as a 5 Stage Bardenpho Process (Dual Anoxic Zones)• (The Bardenpho Process is capable of achieving TN removals < 3

mg/L. )• It can also work as 3 – Stage Bardenpho= A2O Process or Single

Anoxic Zone• (The total nitrogen concentrations less than 8 mg/L can not be

consistently obtained using single anoxic zone processes without methanol supplement )

• Simultaneous denitrification• Cascade DN-N, DN-N process
