Chemical phosphorus removal from wastewater and/or CEPT removal from wastewater using hydrogen peroxide regenerated iron. When applied to plant influents, hydrogen peroxide destroys dissolved and/or total sulfide that otherwise scavenges Fe³⁺ added for CEPT and/or chemical phosphorus removal from wastewater. The foundational aspect of this PRI-TECH application is that one lb of total sulfide theoretically consumes 3.5 lbs Fe³⁺ and thus represents an additional cost of $2 - 3 per lb influent sulfide.

When applied to primary settled solids (prior to thickening/digestion), the effect of the PRI technology is two-fold:
