Hydrogen Peroxide Plus (HPP) is a newly developed, stabilized-H2O2-based compound. This study was aimed at determining the disinfection efficiency of HPP in greywater (GW), assessing HPP dose requirements and evaluating the feasibility of its use in small-scale GW-treatment systems. Fecal coliforms were the most sensitive to treatment, followed by somatic coliphages and F+ bacteriophages. The calculated HPP dose required to reduce fecal coliform counts by 99% was 125 mg H2O2 L-1, with a contact time of 35 min. The use of HPP was found feasible and comparable to the use of chlorine for small systems with a flow rate of 5 m3 d-1. HPP is suggested as an alternative for GW disinfection in small communities and private houses.
