Combined Phosphorus Removal and Recovery
The paper presents directions for a new system technology for municipal wastewater treatment, in order to consider both phosphorus removal and recovery. The system technology is proposed in a way to use as much as possible existing investments for the treatment and focus on modification of the operational mode. The process is based on removal followed by phosphorus recovery as calcium phosphate...
