Innovative methods for removing phosphorus from wastewaters

, : Innovative methods for removing phosphorus from wastewaters. Annali di Chimica 91(3-4): 145-149

Wastewater containing a mixture of hypophosphites and phosphites was treated in order to assess the possibility of attaining high levels of phosphorus oxidation to phosphate. An initial series of tests based on chemical oxidation by means of Fenton's reagent demonstrated the feasibility of this process for solutions containing 250-750 mg/l of phosphorus. Removal yields of up to 98% were attained at pH 3.5 by using variable ratios of (H2O2)/(Fe2+). The second series involved the electrolytic generation of Fenton's reagent at pH 2-2.5 through cathodic oxygen reduction. This demonstrated the possibility of obtaining quantitative yields for solutions containing 80-160 mg/l P with a constant (H2O2)/(Fe2+) ratio of 3.94. Economic comparison of the two processes showed that the operative cost of the electrochemical treatment is comparable to that of the chemical process.
