Leveraging iron sulphide destruction via ORP-controlled microareation to improve phosphate recovery

Vivianite (Fe₃(PO₄)₂·8H₂O) is an attractive product for phosphorus recovery and can form in digested sludge, sediments, and manure when sufficient Fe(II) is available. In wastewater treatment, however, iron sulphides typically outcompete vivianite under anaerobic conditions. To reduce the iron dosag... View More
