Does Biological Phosphorus Removal Process Make Sense When Anaerobic Digestion is Used? – An Analysis With Mass Balance Approach
Phosphorus is associated with algal bloom in the water bodies worldwide and innovative design approaches have been adopted to remove phosphorus from the wastewater. The phosphorus removal processes are based on the two main approaches – chemical phosphorus removal and biological phosphorus removal. Among the two, chemical phosphorus removal is considered more stable and is used when significantly high phosphorus removal is desired, but it also has high operation cost associated. This paper investigates current design approaches which are used for phosphorus removal in the wastewater facilities. This study shows that combined biological-chemical phosphorus removal process require overall 15% to 25% less chemicals and produce approximately 10% less sludge.
