Title: Efficacy and environmental effects of peracetic acid as a sewage disinfectant (231/6/SW)
Author: National Rivers Authority
Document Type: Monograph
Consultants in Environmental Sciences Ltd was commissioned by the National Rivers Authority to conduct a comprehensive review of the programme of largely independent laboratory and field work that has been carried out on the use of peracetic acid (PAA) as a disinfectant for sewage discharges. The economic aspects of PAA treatment were not included in the terms of reference, since they are now reasonably well defined.The objectives of this Study were to review the efficacy of PAA as a sewage disinfectant and the environmental effects of the use of PAA. Evidence has been reviewed from eleven field trials and published literature. PAA for use in sewage disinfection is supplied by Interox Chemicals Ltd as an equilibrium mixture of peracetic acid, acetic acid, hydrogen peroxide and water, marketed under the product name of Oxymaster. As PAA itself is consumed in reaction the equilibrium tends to shift generating more PAA and acetic acid, and depleting the peroxide.
