Electrochemical Recovery of Phosphorus from Acidic Cheese ...

The recovery of phosphorus (P) from high-strength acidic waste streams with high salinity and organic loads is challenging. Here, we addressed this challenge with a recently developed electrochemical approach and compared it with the chemical precipitation method via NaOH dosing. The electrochemical process recovers nearly 90% of P (∼820 mg/L) from cheese ,wastewater, in 48 h at 300 mA with an ...
