Greywater disinfection with the environmentally friendly Hydrogen Peroxide Plus (HPP).
Hydrogen Peroxide Plus (HPP) is a newly developed, stabilized-H(2)O(2)-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 125mg H(2)O(2)L(-1), with a contact time of 35min. The use of HPP was found feasible and comparable to the use of chlorine for small systems with a flow rate of 5m(3)d(-1). HPP is suggested as an alternative for GW disinfection in small communities and private houses.
